Abstract

The Saint-Venant equation of mass balance is used to derive a stochastics lumped model, describing the dynamics of a cross-sectional area in a river. The unknown parameters of the model are estimated by combining the physical equation with a set of data, a method known as grey box modelling. The data consists of water level measurements every minute, at two locations in the river, during a period of nine days. The data was sub sampled to the frequency of 15 minutes. A maximum likelihood method is used to estimate the parameters in the model.
