Hello,

You can use the Porous Media tool to construct the necessary information. To do that, go to Toolbox -> MOHID Land -> Porous Media.

Porous Media tool creates data files with relevant information in case you want to simulate groundwater. These files are (i) soil depth, (ii) bottom digital terrain model, (iii) slope and (iv) initial ground water level.

The Soil Depth tool requires a depression free Digital Terrain Model, which should be selected in the "Select Digital Terrain" box. The parameter to construct soil depth can be set in the "Select Parameter" box. The "Min Depth" and "Max Depth" parameter indicate the minimum and maximum soil depths, respectively. The "Max Slope" parameter indicates the maximum slope which the tool should consider. From these parameters the soil depth is linearly interpolated considering that grid cells with zero slopes will have maximum soil depth and grid cell with slope greater or equal to the maximum slope will have minimum soil depth.

The water depth (water table) parameter indicates the percentage of the initial water depth, in function to the total soil depth. A value of 0% indicates that the initial water table is close to the bottom, a value of 50% indicates that the initial water table is at half soil depth and a value of 100% indicates that the initial water table is closed to the top (fully saturated soil).

Once the parameters are set, click "Press to save all files".

Then in the Porous Media input data file, you can set the water table with the following commands: 

<beginwaterlevel>
NAME                                     : waterlevel
!INITIALIZATION_METHOD   : ASCII_FILE
DEFAULTVALUE                     : 2
REMAIN_CONSTANT             : 0
FILENAME                              : ..\General Data\Digital Terrain\WaterTable.dat
<endwaterlevel>

Please let me know if you require any additional information.

Kind regards,
Luis

Thanks a lot sir.
