Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Continental, Regional-Scale
Model domain	Terrestrial, Hydrology
One-line model description	DHSVM is a distributed hydrologic model that explicitly represents the effects of topography and vegetation on water fluxes through the landscape.
Extended model description	DHSVM is a distributed hydrology model that was developed at the University of Washington more than ten years ago. It has been applied both operationally, for streamflow prediction, and in a research capacity, to examine the effects of forest management on peak streamflow, among other things.
