Streamflow
… in the public eye -> the most important aspect of flooding and hydrology.
… flooding from streams and rivers have the greatest potential to impact human property and lives; although overland flow flooding, mudslides, and landslides are often just as devastating.
… Subsurface flow also enters the stream; although in some instances and regions, stream channels lose water to the groundwater table - regardless, this must be accounted for in the modeling of the stream channel.
… Channels also offer a storage mechanism and the resulting effect is most often an attenuation of the flood hydrograph.
