In that setting, the first flood water to arrive is depleted as it wets the sandy stream bed. The leading edge of the flood thus advances more slowly than later and higher flows.
As a result, the rising limb of the hydrograph becomes ever quicker as the flood moves downstream, until the flow rate is so great that the depletion by wetting soil becomes insignificant.
Flooding in estuaries is commonly caused by a combination of storm surges caused by winds and low barometric pressure and large waves meeting high upstream river flows.
Coastal areas may be flooded by storm surges combining with high tides and large wave events at sea, resulting in waves over-topping flood defenses or in severe cases by tsunami or tropical cyclones.
A storm surge , from either a tropical cyclone or an extratropical cyclone , falls within this category. Research from the NHC National Hurricane Center explains: "Storm surge is an additional rise of water generated by a storm, over and above the predicted astronomical tides.
Storm surge should not be confused with storm tide, which is defined as the water level rise due to the combination of storm surge and the astronomical tide.
This rise in water level can cause extreme flooding in coastal areas particularly when storm surge coincides with spring tide, resulting in storm tides reaching up to 20 feet or more in some cases.
Urban flooding is the inundation of land or property in a built environment , particularly in more densely populated areas, caused by rainfall overwhelming the capacity of drainage systems, such as storm sewers.
Although sometimes triggered by events such as flash flooding or snowmelt , urban flooding is a condition, characterized by its repetitive and systemic impacts on communities, that can happen regardless of whether or not affected communities are located within designated floodplains or near any body of water.
In urban areas, flood effects can be exacerbated by existing paved streets and roads, which increase the speed of flowing water. Impervious surfaces prevent rainfall from infiltrating into the ground, thereby causing a higher surface run-off that may be in excess of local drainage capacity.
The flood flow in urbanized areas constitutes a hazard to both the population and infrastructure. Flood flows in urban environments have been studied relatively recently despite many centuries of flood events.
Catastrophic riverine flooding is usually associated with major infrastructure failures such as the collapse of a dam, but they may also be caused by drainage channel modification from a landslide , earthquake or volcanic eruption.
Examples include outburst floods and lahars. Tsunamis can cause catastrophic coastal flooding, most commonly resulting from undersea earthquakes.
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 percent for warm rain on accumulated snow.
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 the duration 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.
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.
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. Water flowing downhill ultimately encounters downstream conditions slowing movement.
The final limitation in coastal flooding lands is often the ocean or some coastal flooding bars which form natural lakes. In flooding low lands, elevation changes such as tidal fluctuations are significant determinants of coastal and estuarine flooding.
Less predictable events like tsunamis 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 and, especially, by depth of channel, speed of flow and amount of sediments in it  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.
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 beaver dams.
Recent field measurements during the —11 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.
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.
The primary effects of flooding include loss of life and damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals.
Floods also frequently damage power transmission and sometimes power generation , which then has knock-on effects caused by the loss of power.
This includes loss of drinking water treatment and water supply, which may result in loss of drinking water or severe water contamination.
It may also cause the loss of sewage disposal facilities. Lack of clean water combined with human sewage in the flood waters raises the risk of waterborne diseases , which can include typhoid , giardia , cryptosporidium , cholera and many other diseases depending upon the location of the flood.
Damage to roads and transport infrastructure may make it difficult to mobilize aid to those affected or to provide emergency health treatment.
Flood waters typically inundate farm land, making the land unworkable and preventing crops from being planted or harvested, which can lead to shortages of food both for humans and farm animals.
Entire harvests for a country can be lost in extreme flood circumstances. Some tree species may not survive prolonged flooding of their root systems.
Economic hardship due to a temporary decline in tourism, rebuilding costs, or food shortages leading to price increases is a common after-effect of severe flooding.
The impact on those affected may cause psychological damage to those affected, in particular where deaths, serious injuries and loss of property occur.
Urban flooding can cause chronically wet houses, leading to the growth of indoor mold and resulting in adverse health effects, particularly respiratory symptoms.
In the United States , industry experts estimate that wet basements can lower property values by 10—25 percent and are cited among the top reasons for not purchasing a home.
Federal Emergency Management Agency FEMA , almost 40 percent of small businesses never reopen their doors following a flooding disaster.
Floods in particular more frequent or smaller floods can also bring many benefits, such as recharging ground water , making soil more fertile and increasing nutrients in some soils.
Flood waters provide much needed water resources in arid and semi-arid regions where precipitation can be very unevenly distributed throughout the year and kills pests in the farming land.
Freshwater floods particularly play an important role in maintaining ecosystems in river corridors and are a key factor in maintaining floodplain biodiversity.
For some fish species, an inundated floodplain may form a highly suitable location for spawning with few predators and enhanced levels of nutrients or food.
Bird populations may also profit from the boost in food production caused by flooding. Periodic flooding was essential to the well-being of ancient communities along the Tigris-Euphrates Rivers, the Nile River , the Indus River , the Ganges and the Yellow River among others.
The viability of hydropower , a renewable source of energy, is also higher in flood prone regions. In the United States, the National Weather Service gives out the advice "Turn Around, Don't Drown" for floods; that is, it recommends that people get out of the area of a flood, rather than trying to cross it.
At the most basic level, the best defense against floods is to seek higher ground for high-value uses while balancing the foreseeable risks with the benefits of occupying flood hazard zones.
Structures, such as bridges, that must unavoidably be in flood hazard areas should be designed to withstand flooding. Areas most at risk for flooding could be put to valuable uses that could be abandoned temporarily as people retreat to safer areas when a flood is imminent.
Each topic presents distinct yet related questions with varying scope and scale in time, space, and the people involved. Attempts to understand and manage the mechanisms at work in floodplains have been made for at least six millennia.
In the United States, the Association of State Floodplain Managers works to promote education, policies, and activities that mitigate current and future losses, costs, and human suffering caused by flooding and to protect the natural and beneficial functions of floodplains — all without causing adverse impacts.
In many countries around the world, waterways prone to floods are often carefully managed. Defenses such as detention basins , levees ,  bunds , reservoirs , and weirs are used to prevent waterways from overflowing their banks.
When these defenses fail, emergency measures such as sandbags or portable inflatable tubes are often used to try to stem flooding. Coastal flooding has been addressed in portions of Europe and the Americas with coastal defenses , such as sea walls , beach nourishment , and barrier islands.
In the riparian zone near rivers and streams, erosion control measures can be taken to try to slow down or reverse the natural forces that cause many waterways to meander over long periods of time.
Flood controls, such as dams, can be built and maintained over time to try to reduce the occurrence and severity of floods as well.
In the United States, the U. Army Corps of Engineers maintains a network of such flood control dams.
In areas prone to urban flooding, one solution is the repair and expansion of man-made sewer systems and stormwater infrastructure. Another strategy is to reduce impervious surfaces in streets, parking lots and buildings through natural drainage channels, porous paving , and wetlands collectively known as green infrastructure or sustainable urban drainage systems SUDS.
Areas identified as flood-prone can be converted into parks and playgrounds that can tolerate occasional flooding.
Ordinances can be adopted to require developers to retain stormwater on site and require buildings to be elevated, protected by floodwalls and levees , or designed to withstand temporary inundation.
Property owners can also invest in solutions themselves, such as re-landscaping their property to take the flow of water away from their building and installing rain barrels , sump pumps , and check valves.
A series of annual maximum flow rates in a stream reach can be analyzed statistically to estimate the year flood and floods of other recurrence intervals there.
Similar estimates from many sites in a hydrologically similar region can be related to measurable characteristics of each drainage basin to allow indirect estimation of flood recurrence intervals for stream reaches without sufficient data for direct analysis.
Physical process models of channel reaches are generally well understood and will calculate the depth and area of inundation for given channel conditions and a specified flow rate, such as for use in floodplain mapping and flood insurance.
Conversely, given the observed inundation area of a recent flood and the channel conditions, a model can calculate the flow rate. Applied to various potential channel configurations and flow rates, a reach model can contribute to selecting an optimum design for a modified channel.
Various reach models are available as of , either 1D models flood levels measured in the channel or 2D models variable flood depths measured across the extent of a floodplain.
Physical process models of complete drainage basins are even more complex. Although many processes are well understood at a point or for a small area, others are poorly understood at all scales, and process interactions under normal or extreme climatic conditions may be unknown.
Basin models typically combine land-surface process components to estimate how much rainfall or snowmelt reaches a channel with a series of reach models.
For example, a basin model can calculate the runoff hydrograph that might result from a year storm, although the recurrence interval of a storm is rarely equal to that of the associated flood.
Basin models are commonly used in flood forecasting and warning, as well as in analysis of the effects of land use change and climate change.
Anticipating floods before they occur allows for precautions to be taken and people to be warned  so that they can be prepared in advance for flooding conditions.
Flood defences offer only a short-term and local answer and may actually increase the long-term risks. He specifically mentions the massive limestone blocks that reinforce the flood defences.
There were a number of uses for the cut wood, including firewood, fences, thatching spars, furniture and flood defences. It generally is applied to defensive towns walls but can also refer to flood defences and sea walls.
The report found that damage was reduced by flood defences and by timely warnings and evacuations where the defences could not hold back the water.
Examples include building better flood defences and avoiding the building of residential areas near low-lying, flood-prone areas.
The amount of water in the rivers exceeded the capacity of the flood defences and the natural river banks. The existing flood defences were improved as part of an 18 million scheme that was completed in Parts of a fifteenth-century bridge were rediscovered in during excavations for new flood defences.
As of , the flood defences consisted of a concrete seawall, flood sirens and an internal surface storm water drainage system. The improvements have restricted navigation in the lower south-western area, but greatly improved flood defences.
Flood defences which were built in the s to protect the area have been breached to allow water to reclaim the land at high tide and in times of flooding.
A 15 million, year-old proposed flood defence scheme was seen as unlikely to have prevented the flood, but new means of flood defences are being discussed.
They built embankments of sand and earth as look-outs and flood defences known as "cerritos", which can still be seen rising above the dense vegetation which characterises the river delta.
