The table of contents of the manual can be seen on-line.
Also, the introduction of the SahysMod manual can be viewed on line as a .PDF document.
In addition, a PowerPoint slide show can be viewed on-line or downloaded.

The required data per polygon are polygonal
characteristics, hydraulic conductivity and soil
Further data needed are leaching efficiency, parameters of the drainage system, and capillary rise factors.
Seasonal data encompass rainfall, irrigation and evaporation.
The depth of the watertable can be seen in the output
in a row of nodes at a certain time, or in one node
over the whole time period.
The same holds for the soil salinity in the different soil layers, the amount of groundwater flow and the irrigation efficiency.
There are many more output data.
Output graphs can be seen for polygons at a certain
time as well as for period of time in a certain
This graph shows the fluctuation in time of various components of groundwater flow in one of the polygons.
|The soil salinity in the irrigated alluvial fan of Garmsar (Iran) was simulated with SahysMod using a nodal network and an example of results is shown here for Cr4 being the soil salinity of, from year to year, fully rotated cropped areas.|
|The depth of the water table in the irrigated alluvial fan of Garmsar (Iran) was simulated with SahysMod using 89 polygons and an example of results is shown here.|
