Abstract

The main focus of this thesis has been to apply and to develop the storage routing model. The storage routing model is a method of hydraulic numer- ical calculation. It is based on the Saint-Venant equations and works under the quasi steady dynamic wave assumption. It rst creates HPGs and VPGs (respectively upstream water surface elevation and storage as function of the discharge and the downstream water surface elevation) and uses the inter- polations of these graphs at each step of the calculation. This model has been developed for systems composed of circular conduits. In this thesis, at rst the accuracy of the model has been checked for systems with circular pipes, the Wallingford research station and some theoretical models from Matthew A. Hoys thesis [1]. Then the model has been adapted to river sys- tems that include non-prismatic channels with input HPGs/VPGs and has been applied to the Belo Monte canal and the Main Stem Chicago river. The comparison with eld data or with other models results is satisfying, the error (max(abs((xmodel-xdata)/xdata))) is less than 10 % in all the cases. In the last part, a study is made on how the spacing used for the numerical calculation criteria can a ect the accuracy.
