UNSAT-H

Recharge Estimation

UNSAT-H is a FORTRAN computer code used to simulate the one-dimensional flow of water, vapor, and heat in soils. The code addresses the processes of precipitation, evaporation, plant transpiration, storage, and deep drainage. The UNSAT-H computer code is used to understand the movement of water, heat, and vapor in soils so better decisions can be made about land use, waste disposal, and climate change. Example Tests and Typical Applications include studies of the water balance behavior of surface covers over shallow land burial waste sites and studies of land disturbance effects on recharge rates.

The UNSAT-H computer code is managed by the Hydrology Group at the Pacific Northwest National Laboratory (PNNL). PNNL is a U.S. Department of Energy (DOE) multipurpose laboratory, operated for DOE by Battelle Memorial Institute.
