Two packages for meteorological data processing and runoff simulation for personal computers

This paper presents two packages designed to solve some of the most common problems involved in the analysis of a river catchment on a personal computer. The main operations performed concern pre-processing of raw meteorological data (to obtain time series of rainfall, snowfall and daily mean temperatures at different elevations), and simulation of the daily runoff from the catchment. Both packages have been developed at the Laboratorio di Informatica Ambientale e Territoriale (LITA) of the Politecnico di Milano, Italy.
