Elaboration et validation d'un modèle simple de mélange des eaux enestuaire. Application au Bou Regreg (Côte atlantique marocaine)

Abstract

Using morphological data and salinity measurements, a numerical model describing the mixing of water along theBou Regreg estuary was developed. The estuary has been divided into 23 sections, each 1 km in length. The model can be used to calculate the temporal changes of the average salinity for each section at midtide. During the study period the exchanges between the 23 sections were largely governed by dispersion. The model reproduces correctly the salinity variations after a major release of fresh water from an upstream reservoir and also in other situations. © Gauthier-Villars, 1993.
