Grid input files

Grid input files are those files that are read during the calculation process of the core model.

These are the grid files

hssoil.grd, hssoil.grd and flatland.grd

which are all stored in the system/model directory as defined in the configuration.

While flatland.grd has been prepared from GIS as basic grid file, the other two files containing the curve numbers for surface runoff and deep infiltration are produced by a model interface.

Furthermore, a grid file SY_correct.grd is required for adjusting groundwater recharge into groundwater safe yield. Use and modification of this file is done in the post-processing.
