Goals of HSPF

HSPF is a comprehensive model to simulate the continuous event or the steady- state behavior of hydrologic and water quality processes on pervious/impervious land surface and in streams and well-mixed impoundments.

Applications of HSPF

Potential applications of HSPF contain:

Assess the effects of land-use change Reservoir operations Point or nonpoint source treatment alternatives Flow diversions Flood mapping Urban drainage studies River basin planning Studies of water erosion problems In-stream water quality planning

HSPF is accepted by the EPA as a tool for the development
