Planning, land acquisition, river channel maintenance, wetlands protection, and other regulations all help modify development on floodplains and watersheds to reduce their susceptibility to flood damage.

Watershed The total area drained by a river and its tributaries. Same as river basin. Watt A unit of power equal to one joule per second or 107 ergs per second. Wave pole A device for measuring sea-surface waves.

DivideIn hydrologic terms, the high ground that forms the boundary of a watershed. A divide is also called a ridge.

Catchment AreaIn hydrologic terms, an area having a common outlet for its surface runoff (also see Drainage Area or Basin, Watershed).

The magnitude of floods on major watersheds can be characterized in the same way. However, the measurement record on floods is just over 100 years.

drainage divide"The line following the ridges or summits that form the exterior boundary of a watershed, river basin, or catchment.

Response Time: The amount of time in which it will take a watershed to react to a given rainfall event.

Floods may ravish many parts of the globe -- often the result of human destruction of natural watersheds resulting in dramatically increased run-off rates -- but they also increase the circulation of life-giving nutrients within the biosphere.
