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 220.127.116.11 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
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.
