Description :
The AA. tried to determine the various elements of the water balance in a Swiss middleland typical water basin. To obtain this result they correlated pluviometry and elevation on a digitalized grid which elements are 50 m. This allows the elaboration of coordinated maps of the kind as proposed by Nordenson. This requires the establisment of precipitation and evaporation maps (the Turc formula or any can be used) and it also requires a knowledge of the runoff. To illustrate the possibilities of the models constructed, the AA. studied the various characteristics of the Mentue, a river located north of Lausanne (Switzerland).
