Explicit vs. Implicit Time Integration of Saint-Venant Equations for Flood Wave Propagation

The main motivation for this paper arises from the intention to develop a one-dimensional numerical framework which should approximately predict the geometrical and mechanical features, e.g. volume and momentum, of rigid fragments transported by a flow along an open channel. For this purpose a one-dimensional phenomenological constitutive law will be used. Apart from initial and boundary condition for the water flow, appropriate initial and boundary conditions should also be specified for the flow of fragments. Those numerical and mechanical considerations are still in development. However, since the transport process will be mainly affected by the velocity of the flow and the water depth, spatial distribution of both variables should be obtained in advance.
