SaltMod :   agro-hydro-salinity model for drainage, leaching of salts, and land rehabilitation
Totally free download of software

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 modeling (modelling) of reclamation (remediation, rehabilitation, restoration) of saline soils.

The updated version of 5 November 2008 is called SaltMod, previous versions carried the name SaltModW. In March 2012, the auxiliary Fortran programs were eliminated and the contents were integrated into the Delphi program.
Optionally, farmers' responses can be simulated adjusting agriculture and irrigation to waterlogging (water logging) and soil salinity.
A new version of SaltMod was issued on 19 September 2011 which gives the possibility to include the type of crop rotation in the farmers' responses so that, for example, unirrigated (fallow) land can be included in the rotation pattern provided it is not salinized. Further, on 6 February 2012, the farmers' responses were extended with the option to set the maximum soil salinity allowed by them before they begin abandoning part of the land.

The model calculates the actual evaporation from the potential evapotranspiration, the capillary rise and the 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 may consult the publication "Surface Irrigation Software, SURDEV" by M.JurriŽns, 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 and look for publication 59. View here the table of contents. Contact Kselik at ILRI for a copy of Surdev software.

On 3 August 2011, through correspondence with Mrs. Shabnam Alinejad, a bug was detected in the SaltMod model and it was quickly removed. On 24 September the input interface, in some cases, was given a multiple choice box instead of an edit box.

That gives a bitter taste 


A version with a modernized user interface for the input can be made available on request.
On 6 October 2012, thanks to comments made by Jason Keller and Jacob Scherberg, a simpler version of SaltMod was introduced by the name of SaltCalc. It lacks the crop rotation and farmers' response options, but it permits the calculation of monthly instead of seasonal water and salt balances.
