A two-dimensional ® nite element drying-wetting shallow water model for rivers and estuaries

  title={A two-dimensional ® nite element drying-wetting shallow water model for rivers and estuaries},
  author={Mourad Heniche and Yves Secretan and Paul E. Boudreau and Michel Leclerc},
A new ®nite element model has been developed to simulate two-dimensional free surface ̄ow in rivers and estuaries. The variables of the model are the speci®c discharge and the water level. The algorithm takes into account the natural boundaries of the ̄ow, de®ned by the contour lines of zero depth, with a new approach that accepts positive and negative values for the water depth. In this way, we consider a wet or dry area when the water depth is positive or negative respectively. A 6-node… CONTINUE READING
