Summary: SaltMod is a mathematical, numerical computer program for the simulation and prediction of the salinity of soil moisture, ground and drainage water, the depth of the watertable (water table), drain discharge and leaching of salts in irrigated agricultural lands under different geohydrologic conditions, varying watermanagement (water management) options, including the (re)use of groundwater (ground water) for irrigation by pumping from wells (conjunctive use), and several crop rotation schedules. It uses salt and waterbalances (water balance, budget).     The model aims at sustainable land use and environmentally sound optimal water management for sustainability and can be used for the reclamation (remediation, rehabilitation, restoration) of saline soils. Details: The latest version 1.0.1.0 of 5 November 2008 is called SaltMod, previous versions carried the name SaltModW . Optionally, farmers' responses can be simulated adjusting agriculture and irrigation to waterlogging (water logging) and soil salinity. The model calculates actual evaporation from potential evapotranspiration, capillary rise and deep percolation. Values of reference evapotranspiration needed in SaltMod can be found from the CropWat model and ClimWat data base that can be downloaded from the FAO website. For irrigation efficiencies used in SaltMod one may consult the publication "Surface Irrigation Software, SURDEV" by M.Jurriëns, D.Zerihun, J.Boonstra and R.A.L.Kselik. For free download of the scanned publication in PDF format go to the Alterra-ILRI download page. View here the table of contents. Contact Kselik at ILRI for a copy of Surdev software.   Start: The program starts clicking on Saltmod.Exe. More information is given in the program itself.
