Mass and momentum conservation in the simplified flood routing models
W pracy wykazano, że uproszczone modele fal wezbraniowych w postaci fali kinematycznej reprezentują w przypadku liniowych zarówno zasadę zachowania masy jaki i pędu, natomiast w przypadku nieliniowym, reprezentują albo zasadę zachowania masy albo pędu, zależnie od postaci zachowawczej równania. Ponadto wykazano, iż nieliniowa fala dyfuzyjna nie spełnia ani całkowowej zasady zachowania masy ani pędu.

Simulation of unsteady flow over floodplain using the diffusive wave equation and the modified finite element method
We consider solution of 2D nonlinear diffusive wave equation in a domain temporarily covered by a layer of water. A modified finite element method with triangular elements and linear shape functions is used for spatial discretization. The proposed modification refers to the procedure of spatial integration and leads to a more general algorithm involving a weighting parameter. The standard finite element method and the finite difference...

One-Dimensional Modeling of Flows in Open Channels
In this chapter, modeling of the unsteady open channel flow using one-dimensional approach is considered. As this question belongs to the well-known and standard problems of open channel hydraulic engineering, comprehensively presented and described in many books and publications, our attention is focused on some selected aspects only. As far as the numerical solution of the governing equations is considered, one can find out that...
