SPATIAL AGRO-HYDRO-SALINITY MODEL
Description of Principles, User Manual,
and Examples of Application
Sahysmod is a computer program for the simulation and prediction of the salinity
of soil moisture, groundwater and drainage water, the depth of the water-table
and the drain discharge in irrigated agricultural lands under different geo-
hydrologic conditions, varying water management options, including the re-use
of groundwater for irrigation by pumping from wells (conjunctive use),and
several cropping/irrigation rotation schedules, whereby the spatial variations
are accounted for through a network of polygons.
The mathematical model also calculates actual from potential evaporation
(evapotranspiration), capillary rise, deep percolation, and groundwater flow.
Optionally, farmers' responses to irrigation and agriculture can be simulated.
Sahysmod combines the agro-hydro-salinity model SaltMod and the polygonal
ground water model SGMP of my colleague Dr.J.Boonstra.
It allows for the introduction of semi confined aquifers.
