Integrated watershed management

Main components of a watershed

PRECIPITATION: The ultimate source of water to the watershed

CONTINUOUS RIDGELINE: determines the boundary line between adjacent watersheds

CATCHMENT AREA: include all of the land surface area within the surrounding ridgeline

STREAM NETWORK: The primary water body and its tributaries serve as drainage system to collect and drain water from watershed

GROUNDWATER AQUIFER: water stored in underlying soil and rock units that contribute to stream throughout the year

OUTLET: lowest point of watershed, where it discharge to another water body
