  abstract = {{O}ften considered as 'sentinel environments', estuarine zones are complex and fragile environments, on the front line of climate change impacts, particularly sea level rise. {T}he development of a conceptual operating model is a crucial first step toward the development of numerical tools for forecasting the consequences of medium- and long-term change. {T}his study, carried out on an estuary in the {M}editerranean climate of northern {M}orocco, aims to understand the main features of hydrosaline functioning, on the basis of classic physico-chemical parameters such as p{H}, electrical conductivity, redox potential and partial pressure in {O}2, spatialized in the water table and monitored in the wadi (temporary watercourse) during a tidal cycle. {T}he results highlight (1) the predominance of marine forces, with the water table and wadi over-salted (much higher {E}lectrical {C}onductivity) relative to the ocean. {T}hese conditions are maintained because of the low topographic gradient, with the over-salted water not reaching the outlet before the flood; (2) the low freshwater inflows controlled by the inclination of the geological strata, (3) the role of sediment texture on riparian exchanges and the dynamics of the water table, with the clay texture favoring endorheic flows toward piezometric depressions where salts accumulate between two tides because of climatic aridity. {A}ll the processes identified lead to a conceptual model of the estuarine hydrosaline system, explaining the main sources of spatial variability in soil salinity, in line with previous studies, and laying the foundations for numerical modeling aimed at predicting its medium- and long-term evolution under various constraints.},
