Distributed Hydrology Soil Vegetation Model (DHSVM)

Tool Website: http://www.hydro.washington.edu/Lettenmaier/Models/DHSVM/index.shtml

Description

Fully distributed land surface scheme hydrology model that simulates the energy and water balances at each grid cell then route the surface and subsurface flow at each time step. The model also typically has three soil layers and the same snow model as in VIC. It also uses a mosaic of vegetation covers. It typically runs at 150 meter spatial resolution. This is a small scale hydrology model. Typical indicators are: simulated flow ( cfs or cms) - flow conditions; snow water equivalent - water storage (mm) on March 1 or April 1.

Geographic Location

There is a set up at 150 meter spatial resolution over the Puget Sound region and the Olympics. No set up over the Deschutes, OR.

Inputs

daily meteorological dataset pre-processed via VIC for deriving solar radiation and relative humidity. A 1/16th degree gridded meteorological forcing ( 1915-2005) is presently available. The model requires daily precipitation, incoming solar radiation, incoming long wave, relative humidity and wind.

Outputs

3-hourly flow discharge time series at specified locations. Daily maps of snow water equivalent and soil moisture in the total soil column and by soil layers, ( can be customized with all water and energy balance variables) on specified dates only. Basin

Linkage to Other Models

MASS 1 coupled to DHSVM (Richmond and Wigmosta)

Level of Effort

Set up of GIS files ( stream network, road network, vegetation and soil maps), meteorological stations and calibration. Minimum Time: 1 month if using a GIS specialist.
