5.7 Land use

Figure 37 provides an overview of the Land use tab. Settings in the Land use tab affect the calculation of the potential evapotranspiration. In this tab the user has to select a land use map and a lookup table containing crop coefficients for each land use class.

The land use map is a nominal map with land use classes which can be selected and added to the map canvas by clicking the Select map button. An example of a land use map that has been selected and added to the canvas is shown in Figure 38.

A table with a crop coefficient for each land use class defined in the land use map can be added to the GUI by clicking the Select table button. After clicking this button you will be asked to select a *.tbl file inside the Input folder. Figure 39 shows an example of the format of a crop coefficients lookup table that corresponds with the land use map of Figure 38.

After completion of the settings in the Land use tab the user can continue with the next tab: Glaciers.
