Die Modellierung erfolgt in zwei Schritten. Zum einen gibt es die Langzeitsimulationen zur Abbildung der langfristigen Prozesse und zur Einstellung des langzeitlichen Wasserhaushaltes und zum anderen die Kurzzeitsimulation zur möglichst genauen Abbildung von einzelnen Ereignissen auf Grundlage der Langzeitberechnungen. Die hierfür benötigten Daten beschränken sich auf die diskreten Messdaten wie den Niederschlag, die Verdunstung  und den Abflüssen bzw. Wasserständen selbst.

Pre Processing of Time Series

The modelling is carried out in two steps. Firstly, there are the long-term simulations to map the long-term processes and compute the long temporal water balance. On the other hand, the short-term simulation is used for giving an accurate computation of individual events on the basis of long-term calculations. The data required for this are limited to the discrete measurement data such as precipitation, evaporation and run off and the water levels.

Finally, the discrete precipitation data are distributed on the area of the sub catchments. In KalypsoHydrology, own precipitation, temperature and evaporation characteristics are assigned to each sub area. There are different methods to determine the precipitation in a particular area; for example: The Thiessen Polygon Method.
