Improved flood modeling. Flooding, whether from rivers overflowing their banks or in coastal regions, is among the most costly natural disasters. Altimetry data from the SWOT mission will make it possible to measure the 3-dimensional shape of flood waves, track floodwater levels, and improve measurements of local topographic details in floodplains.
Floods are caused by many factors or a combination of any of these generally prolonged heavy rainfall (locally concentrated or throughout a catchment area), highly accelerated snowmelt, severe winds over water, unusual high tides, tsunamis, or failure of dams, levees, retention ponds, or other structures that retained the water.

Landscaping to prevent water from damaging your home or flooding your basement is a smart strategy. Learn seven easy steps that everyone, from gardening newbies to seasoned pros, can try.
Flooding occurs when a watercourse is unable to convey the quantity of runoff flowing downstream. The frequency with which this occurs is described by a return period. Flooding is a natural process, which maintains ecosystem composition and processes, but it can also be altered by land use changes such as river engineering. Floods can be both ...
There are several types of urban flooding, each with a different cause. City planners distinguish pluvial flooding (flooding caused by heavy rain), fluvial flooding (caused by a nearby river overflowing its banks), or coastal flooding (often caused by storm surges). Urban flooding is a hazard to both the population and infrastructure.
A BAER plan is developed based on the risk assessments and burned area land management objectives. The BAER Plan identifies the most effective treatments to address the identified risks. Plan implementation timeframes are dictated primarily by anticipated future events (e.g., next significant rainstorm) which also influence treatment options.
