Flash Floods: It's More Than a Bunch of Rain

Matt Kelsch - UCAR/COMET, Boulder, Colorado 


"Flash Floods are one of the deadliest of all weather phenomena. Flash floods are not purely meteorological event. They involve important components of both meteorology and hydrology, which makes them hydrometeorology events. Rainfall amounts, and in particular the rainfall rates, are the important meteorological contributors to flash floods.  Then what happens to all the rainwater once it is on the ground--the hydrology--is equally important.

This talk will examine the key characteristics of the rainfall and the hydrologic response that affects the locations, timing and severity of flash floods. We will talk about short-term bursts of intense rainfall and the importance of ground surface conditions, including conditions such as soil saturation, steep drainages, urban development, and forecast fires.
