| Zusammenfassung |
| The present paper introduces an analytical approach for the
description of the soil water balance and runoff production within
a schematic river basin. The model is based on a stochastic
differential equation where the rainfall is interpreted as an
additive noise in the soil water balance and is assumed uniform
over the basin, the basin heterogeneity is characterized by a
parabolic distribution of the soil water storage capacity and the
runoff production occurs for saturation excess. The model allowed
to derive the probability density function of the produced surface
runoff highlighting the role played by climate and physical
characteristics of a basin on runoff dynamics. Finally, the model
have been tested over a humid basin of Southern Italy proposing
also a strategy for the parameters estimation. |
