The amount, location, and timing of water reaching a drainage channel from natural precipitation and controlled or uncontrolled reservoir releases determines the flow at downstream locations. Some precipitation evaporates, some slowly percolates through soil, some may be temporarily sequestered as snow or ice, and some may produce rapid runoff from surfaces including rock, pavement, roofs, and saturated or frozen ground. The fraction of incident precipitation promptly reaching a drainage channel has been observed from nil for light rain on dry, level ground to as high as 170 percent for warm rain on accumulated snow.[9]

Most precipitation records are based on a measured depth of water received within a fixed time interval. Frequency of a precipitation threshold of interest may be determined from the number of measurements exceeding that threshold value within the total time period for which observations are available. Individual data points are converted to intensity by dividing each measured depth by the period of time between observations. This intensity will be less than the actual peak intensity if theduration of the rainfall event was less than the fixed time interval for which measurements are reported. Convective precipitation events (thunderstorms) tend to produce shorter duration storm events than orographic precipitation. Duration, intensity, and frequency of rainfall events are important to flood prediction. Short duration precipitation is more significant to flooding within small drainage basins.[10]

The most important upslope factor in determining flood magnitude is the land area of the watershed upstream of the area of interest. Rainfall intensity is the second most important factor for watersheds of less than approximately 30 square miles or 80 square kilometres. The main channel slope is the second most important factor for larger watersheds. Channel slope and rainfall intensity become the third most important factors for small and large watersheds, respectively.[11]

Time of Concentration is the time required for runoff from the most distant point of the upstream drainage area to reach the point of the drainage channel controlling flooding of the area of interest. The time of concentration defines the critical duration of peak rainfall for the area of interest.[12] The critical duration of intense rainfall might be only a few minutes for roof and parking lot drainage structures, while cumulative rainfall over several days would be critical for river basins.

Downslope factors

Water flowing downhill ultimately encounters downstream conditions slowing movement. The final limitation is often the ocean or a natural or artificial lake. Elevation changes such as tidal fluctuations are significant determinants of coastal and estuarine flooding. Less predictable events liketsunamis and storm surges may also cause elevation changes in large bodies of water. Elevation of flowing water is controlled by the geometry of the flow channel.[11] Flow channel restrictions like bridges and canyons tend to control water elevation above the restriction. The actual control point for any given reach of the drainage may change with changing water elevation, so a closer point may control for lower water levels until a more distant point controls at higher water levels.

Effective flood channel geometry may be changed by growth of vegetation, accumulation of ice or debris, or construction of bridges, buildings, or levees within the flood channel.

Coincidence
San Francisco Water Damage.
Extreme flood events often result from coincidence such as unusually intense, warm rainfall melting heavy snow pack, producing channel obstructions from floating ice, and releasing small impoundments like beaverdams.[13] Coincident events may cause extensive flooding to be more frequent than anticipated from simplistic statistical prediction models considering only precipitation runoff flowing within unobstructed drainage channels.[14] Debris modification of channel geometry is common when heavy flows move uprooted woody vegetation and flood-damaged structures and vehicles, including boats and railwayequipment. Recent field measurements during the 2010–2011 Queensland floods showed that any criterion solely based upon the flow velocity, water depth or specific momentum cannot account for the hazards caused by velocity and water depth fluctuations.[7] These considerations ignore further the risks associated with large debris entrained by the flow motion.[8]
Damage Restoration Company San Francisco.
Some researchers have mentioned the storage effect in urban areas with transportation corridors created by cut and fill. Culverted fills may be converted to impoundments if the culverts become blocked by debris, and flow may be diverted along streets. Several studies have looked into the flow patterns and redistribution in streets during storm events and the implication on flood modelling.[15]

Hurricanes, good thing they don't come around San Francisco

We should be very happy that Floods and Water Damage situations do not come around in San Francisco , California.
That are associated with Hurricanes.

Hurricanes are giant, spiraling tropical storms that can pack wind speeds of over 160 miles (257 kilometers) an hour and unleash more than 2.4 trillion gallons (9 trillion liters) of rain a day. These same tropical storms are known as cyclones in the northern Indian Ocean and Bay of Bengal, and as typhoons in the western Pacific Ocean.
San Francisco Water Damage Restoration Company 800-980-8003
The Atlantic Ocean’s hurricane season peaks from mid-August to late October and averages five to six hurricanes per year.
Water Damage Repair San Francisco
Hurricanes begin as tropical disturbances in warm ocean waters with surface temperatures of at least 80 degrees Fahrenheit (26.5 degrees Celsius). These low pressure systems are fed by energy from the warm seas. If a storm achieves wind speeds of 38 miles (61 kilometers) an hour, it becomes known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles (63 kilometers) an hour. When a storm’s sustained wind speeds reach 74 miles (119 kilometers) an hour it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.

Hurricanes are enormous heat engines that generate energy on a staggering scale. They draw heat from warm, moist ocean air and release it through condensation of water vapor in thunderstorms.

Hurricanes spin around a low-pressure center known as the “eye.” Sinking air makes this 20- to 30-mile-wide (32- to 48-kilometer-wide) area notoriously calm. But the eye is surrounded by a circular “eye wall” that hosts the storm’s strongest winds and rain.

These storms bring destruction ashore in many different ways. When a hurricane makes landfall it often produces a devastating storm surge that can reach 20 feet (6 meters) high and extend nearly 100 miles (161 kilometers). Ninety percent of all hurricane deaths result from storm surges.

A hurricane’s high winds are also destructive and may spawn tornadoes. Torrential rains cause further damage by spawning floods and landslides, which may occur many miles inland.

The best defense against a hurricane is an accurate forecast that gives people time to get out of its way. The National Hurricane Center issues hurricane watches for storms that may endanger communities, and hurricane warnings for storms that will make landfall within 24 hours.

Flood Damage preparedness San Francisco

Here are some safety tips to prepare for rising water—and what to do once a flood has begun.
Get Ready for El NiƱo conditions,  San Francisco, California.
Safety Tips

Before a Flood

Avoid building in a floodplain.Construct barriers (levees, beams, floodwalls) to stop floodwater from entering your home.Seal walls in basements with waterproofing compounds to avoid seepage.If a flood is likely in your area, listen to the radio or television for information.Know the difference between a flood watch and aflood warning. A watch means flooding is possible. A warning meansflooding is occurring or will occur soon.
San Francisco Water Damage Restoration Company 415-861-8003
When a Flood is Imminent

Be prepared! Pack a bag with important items in case you need to evacuate. Don't forget to include needed medications.If advised to evacuate your home, do so immediately.If there is any possibility of a flash flood, move immediately to higher ground.If possible, bring in outdoor furniture and move essential items to an upper floor.Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances.

During a Flood
In San Francisco, Bay Area.
Do not walk through moving water. As little as 6 inches (15 centimeters) of moving water can make you fall.If you have to walk in water, wherever possible, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely.Do not touch electrical equipment if you are wet or standing in water.

After a Flood
San Francisco, California
Listen for news reports to learn whether the community's water supply is safe to drink.Avoid floodwaters; water may be contaminated by oil, gasoline, or raw sewage. Water may also be electrically charged from underground or downed power lines.Avoid moving water.Be aware of areas where floodwaters have receded. Roads may have weakened and could collapse under the weight of a car.Stay away from downed power lines, and report them to the power company.Return home only when authorities indicate it is safe.Stay out of any building if it is surrounded by floodwaters.Service damaged septic tanks, cesspools, pits, and leaching systems as soon as possible. Damaged sewage systems are serious health hazards.Clean and disinfect everything that got wet. Mud left from floodwater can contain sewage and chemicals.

Restoration tips when you experience Water Damage at your San Francisco home.

Protecting your home from water damage in San Francisco, California
We provide immediate assistance 24 / 7,  in San Francisco we have Response time 30 to 40 minutes.

The first signs of water damage might seem trivial. But warnings like water stains on the ceilings or a leak under the kitchen sink can lead to real problems, like a weakened roof or rotten floorboards. A burst pipe can even damage your furniture and other personal possessions. Why take a chance? Learn where your home is most likely to suffer water damage, and what you can do to help prevent it.

Inside your home in San Francisco

Kitchen

Dishwasher – Periodically check for leaks under the sink where the hose connects to the water supply. Look around the base of the dishwasher for evidence of leaks, such as discolored, warped, or soft flooring materials, or water damage to nearby cabinets.Refrigerator – If your refrigerator has an icemaker, make sure the hose connection is securely attached to the water supply line. Also, a wet spot on the floor may be a sign of a crimped icemaker line about to burst.Sink – Replace deteriorated caulk around sinks, and check the pipes under the sink for leaks. A slow-draining pipe may indicate a partially blocked drain that needs cleaning.

Bathroom

Showers and bathtubs – Remove and replace deteriorated or cracked caulk and grout. Water can leak through these damaged sealants, causing stains or soft areas around nearby walls and floors.Sinks – Check under the sink for leaks from water supply lines or drainpipes.Toilets – Clogs can result from too much toilet paper or objects such as hanging bowl deodorants. Also, some chlorine tablet cleaners may corrode internal plastic or rubber parts, leading to a leak.

Basement, Laundry or Utility room at your San Francisco property

Washing machine – Check hoses regularly for bulging, cracking, fraying, and leaks around hose ends. Replace the hose if a problem is found or every three to five years as part of a proactive maintenance program. To help make sure the hose doesn’t kink, leave at least four inches (or 11 centimeters) between the water connection and the back of the washing machine.Water heater – Most water heaters last eight to 15 years. Wet spots on the floor or a rusted tank may signal a leak. Water heaters should be installed on the lowest level of the home, next to a floor drain, or inside a drain pan piped to the floor drain.Sump pump – Battery-operated back-up sump pumps can help protect against power failure or failure of the primary pump. Test the sump pump before the start of each wet season. Sump pumps are not intended to last more than 10 years and must have some components replaced or serviced within those 10 years.

Since water may still come through an overflowing drain or cracks in the foundation walls, make sure items stored in the basement are kept off the floor. Furniture should be on casters or shims and arranged away from floor drains.
Stopping leaks at the source

Check for hidden leaks. First, turn off faucets and all water-using appliances, and don’t flush toilets for one hour. Then, record the water meter reading. If the flow indicator (triangular or diamond-shaped rotating button) is spinning or the meter reading has changed while no water is being used, a leaking pipe may exist.Make sure everyone in your household knows where the water shutoff valve is and how to open and close it. Check it frequently for problems, and shut off the water if you will be away from your home for several days or longer.Outside Your Home

Roof leaks in San Francisco are very common, especially when comes to old Victorian style homes.

Keep the roof free from leaves, twigs, and other litter to allow for proper drainage.Make sure air can flow freely through all soffit and roof vents. This will reduce the buildup of heat and moisture and help extend the life of the roof.Consult a professional on using a preservative or cleaner (depending on the type of roof you have) to help limit the weathering effects of moisture and retard growth of molds and mosses.Keep trees trimmed to prevent them from rubbing against the roof or providing excessive shade.Replace missing, curling, cupping, broken, or cracked shingles.Watch for damage in valley areas of the roof, and around the flashing at chimneys, vents, and other junctions.Check your attic around flues, plumbing vents, and chimneys for roof leaks, especially if you’ve noticed water stains on the ceiling.

From the gutters to the ground

Clean debris from your gutters and downspouts, and inspect them regularly. Think about installing gutter shields if your gutters frequently fill with debris.Place splash blocks at the end of downspouts to carry water away from the foundation, or add an extra length of downspout if necessary.Every spring, have the air conditioning (A/C) system serviced by a qualified contractor. Make sure their service includes inspecting and cleaning the A/C condensation pan drain line. Change the air filters on a regular basis.Before winter starts, disconnect garden hoses from all spigots and turn off each spigot’s water supply.Replace any damaged caulk around windows or doors.Repaint wood siding as needed.Fill in any low spots next to the house to help water drain away from the foundation.Hardware that can help

Even after taking the preventions we’ve discussed here, check frequently around the house for signs of leaks. It’s important to find them before they cause serious damage. Of course, it’s impossible to keep watch for signs of trouble 24 hours a day. Fortunately there are water leak detection systems that can help.

Water alarms are now available in San Francisco

These systems are usually battery-operated, stand-alone units. The moisture sensor on the device will sound an alarm when it senses moisture.Water alarms are inexpensive and easy to install. They can be placed on the floor or mounted on a wall. They should be located in high-risk areas such as under sinks and near appliances and equipment that use water.This device can help only if someone is inside the home, hears the alarm, and takes action.

Individual appliance systems

These systems are installed on a specific appliance and will automatically shut off the water supply in case of a leak.Depending on the type of device, you may be able to install this system without any special tools. However, in some cases, a qualified plumber may be needed.

Whole-house systems

These systems feature a shut-off valve that is installed on the main water supply pipe. When a leak is detected, the system will automatically shut off the entire water supply.If you travel often, this type of system could help you rest assured while you are away from home.Whole-house systems typically take between four and six hours to install and a qualified plumber is normally required.

Water-borne risks 
Flood waters and water damage from this emergency will pose special problems for the thousands of people with existing lung disease and may increase the likelihood of the development of lung disease. Water damage from rains associated with a hurricane can pose risks to the public well outside of the floodwater area.

Standing water remaining from any flood is a breeding ground for microorganisms. Bacteria, viruses, and mold can become airborne and be inhaled, putting people at risk for lung disease. With the reports of sewage and toxins in the water, the floodwaters here will likely exacerbate the growth of microorganisms.  Even when the flooding is due to a fairly clean source, such as rain water, the growth of these microorganisms can cause allergic reactions in sensitive individuals.The greatest health risk for the general public in this emergency may come from water-borne microorganisms and toxins.  However, even after the water recedes, the contaminants, bacteria, viruses and mold left behind pose a risk to those with preexisting lung disease.  Exposure to these microorganisms and toxins may increase the risk of developing lung disease. In addition, the time spent in large group housing may increase the risk of spread of infectious diseases, such as influenza, pneumonia, and tuberculosis. Damp buildings and furnishings promote the growth of microorganisms, dust mites, cockroaches and mold, which can aggravate asthma and allergies and may cause the development of asthma, wheeze, cough and hypersensitivity pneumonitis in susceptible persons.After this emergency, contaminants and microorganisms may be inhaled during clean up efforts, which also add to lung disease complications. Clean up efforts will need to protect the workers and occupants from exposure to airborne particles and gases.The physical stress of dealing with the flood may also put a strain on people who are already ill or the elderly, providing an opportunity for respiratory infections and other sicknesses to arise. Much of the damaged materials and furnishings in homes and buildings will have to be discarded because of the spread of contaminated water. Simply drying out the water will not remove the contaminants or the microorganisms.After the flood or water damage, cleaning up is imperative. Materials which can be cleaned must be cleaned thoroughly. Materials which cannot be cleaned or are damaged beyond use must be discarded. Excess moisture indoors poses an indoor air quality concern for the following reasons: Areas with this high level humidity and moist materials provide an ideal environment for the growth of microorganisms, which could result in continued or additional health hazards such as allergic reactions.Coming into contact with air or water that contains these microorganisms can make a person sick.Long-term high levels of humidity can foster growth of dust mites, which can cause asthma and trigger allergic reactions and asthma attacks.Although the clean up process can take a long time, it is necessary to protect health.  These are tasks that must be done:Stop the water intrusions first.Identify and protect vulnerable populations, which include children, the elderly and anyone with chronic diseases or a suppressed immune system.Identify the extent of the contamination. Be sure to trace the pathways of the water to find where damage has spread.Plan and carry out the clean up.  The clean up plan should include these steps:Contain the damaged materials and furnishings and protect workers and occupants from exposure to them.Clean and dry out materials that can be completely dried.Remove damaged materials that cannot be completely dried, including any materials that cannot be thoroughly cleaned and dried in 24 to 48 hours.Evaluate whether the space has been successfully cleaned.Repair and reconstruct the spaces to prevent or limit the possibility of recurrence.There are no accepted standards for airborne biological contaminants, including mold.  There are no accepted standards for interpreting sampling of the air to determine extent of a problem or clean up. Air cleaning devices can help remove some indoor air pollution, but won’t solve the problems alone.  Cleaning up the water, the contaminants, and the damaged furnishings and material are essential steps and nothing can substitute for them.  Avoid using air cleaning devices that emit ozone. Ozone has not been found to clean indoor air, including mold problems. Ozone can harm lung health, especially for children, the elderly, and people with asthma and chronic lung diseases.For more help on cleaning up after a flood or water damage, contact the American Lung Association Help Line at 1-800-LUNGUSA.

Emergency power risks
Without electricity, people may turn to portable gasoline- or diesel-powered generators, gas stoves, charcoal stoves, grills, portable camping stoves and other devices to cook indoors.  Carbon monoxide is produced whenever any fuel such as gas, oil, kerosene, wood, or charcoal is burned. Exposure to carbon monoxide reduces the blood's ability to carry oxygen and can lead to death.

Do not use ovens and gas ranges to heat your home.Do not burn charcoal or propane inside a home, cabin, recreational vehicle or camper.Do not operate gasoline-powered or diesel-powered engines indoors.
