Fluid Flow on Vegetated Hillslope (2006.14367v1)

Abstract: In this paper, we present a deduction of swallow water equations in the presence of vegetation based on spatial averaging techniques starting from the general principles of conservation of mass and momentum. For this purpose, we worked in the hydrostatic approximation of the pressure field and we considered certain hypotheses of kinematic and topographical nature and assumptions on the structure of the vegetation. Some elements of differential geometry necessary to facilitate the reading of the paper can be found in the Appendix.
