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 more informed 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.
