A simple wetting and drying method for shallow water flow with application in the Vitória Bay estuary, Brazil

Abstract: This paper presents a simple and effective method to model wetting and drying processes in natural water bodies. The proposed method has been nicknamed "rough-porous layer", or RPL. It bears similarities with the so called marsh porosity method, but is simpler to implement, mass conserving and does not affect wave celerity in wet areas. The method can be easily implemented in finite element models, what makes it useful in numerical modeling of natural water bodies with intricate topographies. A standard testin… Show more
