Climatic data
Daily values of the minimum and maximum temperature, humidity and wind speed come from the weather
station Brandis located within the Parthe watershed.
Data from 18 raingauges are used for precipitation. The precipitation data are linearly interpolated by SME. The map shows the location of the weather station Brandis (red) and the raingauges (blue). |

Elevation
For the elevation a Digital Elevation Model with a grid size of 200 m was used, which is based
on the Atkis-DEM 20 m x 20 from the Landesvermessungsamt Sachsen. The studyarea map, the flowdirection map and a slope
map are derived from the elevation map. The flowdirection map is needed to calculate the surface water runoff.
The slope influences the infiltration rate and the surface water runoff.

Landuse
The landuse data come from the federal state of Saxony and are are based on a classification of color infrared images. For the model, these data have been aggregated to the classes "open water", "forest", "agriculture" and "residential areas". Landuse dependent parameters were taken from the Patuxent Landscape Model, but sowing and harvesting data have been adjusted to regional values.

Soil
The soil data used in the model are based on the Thomas-Lauckner soil map. The soil hydraulic parameters hydraulic conductivity, porosity, field capacity were derived from the soil texture according to the Bodenkundliche Kartieranleitung (AG Boden, 1996).
