 The surface water supply is displayed as annual average available water runoff. Using the INVEST water yield model, the annual average quantity of water runoff from each subcatchment of the Alpine space is calculated. The model estimates the water runoff based on gridded information on climatic, soil, topographic and landcover characteristics.

 As most input data, were physically determined values, and hence are not to be changed. The calibration, after assessing the sensitivity was done with the annually average evapotranspiration coefficient. Therefore, comparing the dataset with the observation-based map of mean annual runoff from Beck (2012), step-wise adjustments of the KC- (Evapotranspiration coefficient table)values are made towards minimising the error to reach a threshold of max 10-15 % error rate. This was done in a semi-automatic calibration scheme in python and R environment.
