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
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
Polygonal input screen of SahysMod program:
