VCRat 2.6 (Dec. 2008)Ventura County Watershed Protection DistrictVentura County Watershed Protection District 

800 S. Victoria Ave., Ventura, CA 93009		The VCRat model is based on the Modified Rational Method (MRM) and calculates a hydrograph of runoff at all subarea collection points within the watershed, combines hydrographs from each subarea, and routes the combined hydrograph through the channel system.

Manual and the training materials are available from the District.

Only accepted for usage within the Ventura County, California area.
