Mathematical modelling of water flows processes in rivers and open channels for many years has been target of researches for hydrotechnics and hydrologists. For flows forecasting in open channels models based on one-dimensional equations are mostly used. This models are assuming that the main flow component is parallel to the channel axis is substantially larger than others, so it can ignore them. One of the most effective methods for solving de Saint-Venant equations is the finite difference method with using four-point Preissman Scheme. In this paper an analysis of the impact of Preissman weighting parameters on flows in the lower Odra river network.
