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 water table, drain discharge and leaching of salts in irrigated agricultural lands under different geohydrologic conditions, varying water management options, including the (re)use of groundwater for irrigation by pumping from wells (conjunctive use), and several crop rotation schedules. It uses salt and water balances (budgets).
    The model aims at sustainable land use and environmentally sound optimal water management for sustainability and can be used for the modeling of reclamation (remediation, rehabilitation, restoration) of saline soils.

Optionally, farmers' responses can be simulated adjusting agriculture and irrigation to waterlogging 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.

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.

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.
