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 18.104.22.168 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 Februari 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

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