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]

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.

Water Damage Restoration Company San Francisco, What to do when you have Water damage situation.

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.

Water Damage Restoration Guide

San Francisco Water Damage Restoration Guide. 415-861-8003
EPA presents strategies to respond to water damage within 24-48 hours. These guidelines are designed to help avoid the need for remediation of mold growth by taking quick action before growth starts. If mold growth is found on the materials listed in Table 1, refer to Table 2 for guidance on remediation. Depending on the size of the area involved and resources available, professional assistance may be needed to dry an area quickly and thoroughly.

Go to Table 2 | Go back to Investigating, Evaluating, and Remediating Moisture and Mold Problems

Water-Damaged Material †ActionsBooks and papersFor non-valuable items, discard books and papers.Photocopy valuable/important items, discard originals.Freeze (in frost-free freezer or meat locker) or freeze-dry.Carpet and backing - dry within 24-48 hours §Remove water with water extraction vacuum.Reduce ambient humidity levels with dehumidifier.Accelerate drying process with fans.Ceiling tilesDiscard and replace.Cellulose insulationDiscard and replace.Concrete or cinder block surfacesRemove water with water extraction vacuum.Accelerate drying process with dehumidifiers, fans, and/or heaters.Fiberglass insulationDiscard and replace.Hard surface, porous flooring §(Linoleum, ceramic tile, vinyl)Vacuum or damp wipe with water and mild detergent and allow to dry; scrub if necessary.Check to make sure underflooring is dry; dry underflooring if necessary.Non-porous, hard surfaces

Dryfast respond to Water Damage calls 24-hour 7 days a week serving all of San Francisco.

* If mold growth has occurred or materials have been wet for more than 48 hours, consult Table 2 guidelines. Even if materials are dried within 48 hours, mold growth may have occurred. Items may be tested by professionals if there is doubt. Note that mold growth will not always occur after 48 hours; this is only a guideline.

These guidelines are for damage caused by clean water. If you know or suspect that the water source is contaminated with sewage, or chemical or biological pollutants, then Personal Protective Equipment and containment are required by OSHA. An experienced professional should be consulted if you and/or your remediators do not have expertise remediating in contaminated water situations. Do not use fans before determining that the water is clean or sanitary.

† If a particular item(s) has high monetary or sentimental value, you may wish to consult a restoration/water damage specialist.

§ The subfloor under the carpet or other flooring material must also be cleaned and dried. See the appropriate section of this table for recommended actions depending on the composition of the subfloor.
