DPM Version 3 - A Deep Percolation Model for Estimating Ground-Water Recharge

DPM Version History

DPM Version 3.0 was released September 30, 2008. DPM Version 3.0 enhances DPM Version 2 by making it consistent with a modularized version of DPM included in the U.S. Geological Survey’s Modular Modeling System (Vaccaro, 2007). Revisions include the addition of new land-use/land-cover options, the simulation of snowmelt during rain-on-snow conditions as a function of windspeed, the estimation of incoming solar radiation if no solar radiation data are available, the option of applying irrigation above or below the vegetation canopy, the option of distributing precipitation areally using monthly instead of annual weighting factors, reading input and output file names externally to the program, and sizing arrays so it is less likely that users will need to recompile the program. DPM Version 3.0 fixes bugs in subroutines APPSCD, CRPCOF, SAGE, SPRGWT, WWAUTM, and WWSPRG. DPM Version 3.0 is backward compatible with datasets created for DPM Version 2.

DPM Version 2 was released in 1997 (Bauer and Mastin, 1997). In DPM Version 2, the requirement for a quadrilateral model-grid system was eliminated; the ability to allow the soils in the root or soil zone to saturate was added; the method used to calculate surface runoff in the model was changed to a combination of an approximation of Darcy flow for saturated soils and saturation excess; and the Priestly-Taylor potential evapotranspiration method was added for non-agricultural land-use/land-cover options. Agricultural land-use/land-cover options continued to use the original Jensen-Haise method of DPM Version 1. A revision to DPM Version 2 incorporated after 1997 included the option of specifying time-varying vertical hydraulic conductivities of soils.

DPM Version 1 was released in 1987 (Bauer and Vaccaro, 1987).
