For the simulation of water flow in rivers presently a network approach is applied. This approach is based on coupled ld models and should be extended to 2d submodel elements. Special difficulties arise due to the free boundaries caused by the wetting and drying and the source terms accounting for the sloping river bed and friction.

A first order Roe scheme is adapted to these difficulties and is presented for a robust numerical solution method.
