For the determination of hydraulic aquifer properties like hydraulic conductivity used in SahysMod one may consult the pumping test publication "Software for Aquifer Test Evaluation, SATEM" by J.Boonstra and R.A.L.Kselik. For free download of the scanned publication in PDF format go to the Alterra-ILRI download page. View here the table of contents.
For irrigation efficiencies used in SahysMod one may consult the publication "Surface Irrigation Software, SURDEV" by M.Jurriëns, 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. View here the table of contents.
Mail to Kselik at ILRI to obtain free copy of the Satem or Surdev software.
The model calculates actual from potential evaporation (evapotranspiration), capillary rise,deep percolation, and groundwater (ground water) flow. Values of reference evapotranspiration needed in SahysMod can be found from the CropWat model and ClimWat data base that can be downloaded from the FAO website.
