Filter Strip

A linear strip of land maintained to slow the velocity of runoff and filter sediment.

Filtration

The mechanical process which removes particulate matter by separating water from solid material, usually by passing it through sand. .

Flooding

Occurs when the total volume of surface water runoff and baseflow entering a stream channel exceeds the capacity of the channel resulting in out-of-bank flow.

Floodplain

That portion of a stream valley adjacent to the channel that is created by erosion and sediment deposited from the stream and covered with water when the stream overflows its banks at flood stage. Also, the nearly level land situated on either side of a channel that is subject to overflow flooding.
