Resumo

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 testing case of a basin with variable slope is used for validations and comparison with other methods.The effectiveness of the RPL is better evaluated in modeling the complex Vitória Bay estuary (Brazil) with its extensive mangrove areas.
