The plate of phosphate is a geographical zone distributed between three basins slopes: The catchment area of Oum Rbia, the catchment area of Mallah Wadi and the basins slopes of Chaouia. These basins slopes are located in Morocco power station. They are thus exposed to disturbed oceanic flows coming from North and of Western North. The basins slopes of Chaouia and particularly those of the plate of Settat-Ben Ahmed are characterized by a little developed hydrographic network. It is hardly made up by the ends down streams of the wad is going down from the plate. These water ways, not having a discharge system towards the sea, they cross the plain of Berrechid on about ten kilometers before atrophying itself there. They are with temporary flow, their water arrive on the plain, they are then evaporated or percolate towards the tablecloth, therefore one speaks about a endoreic hydrography.
Author Keywords: flash floods, Semi-arid, Watershed area.

Abstract
The plate of phosphate is a geographical zone distributed between three basins slopes: The catchment area of Oum Rbia, the catchment area of Mallah Wadi and the basins slopes of Chaouia. These basins slopes are located in Morocco power station. They are thus exposed to disturbed oceanic flows coming from North and of Western North. The basins slopes of Chaouia and particularly those of the plate of Settat-Ben Ahmed are characterized by a little developed hydrographic network. It is hardly made up by the ends down streams of the wad is going down from the plate. These water ways, not having a discharge system towards the sea, they cross the plain of Berrechid on about ten kilometers before atrophying itself there. They are with temporary flow, their water arrive on the plain, they are then evaporated or percolate towards the tablecloth, therefore one speaks about a endoreic hydrography.

Abstract: (french)
Le plateau du phosphate est une zone répartie géographiquement sur trois bassins versants : le bassin versant d'Oum Rbia, le bassin versant d'Oued Mallah et les bassins versants de Chaouia. Ces bassins versants sont situés dans le Maroc centrale. Ils sont donc exposés aux flux océaniques perturbés en provenance du Nord et du Nord Ouest. Les bassins versants de Chaouia et particulièrement ceux du plateau de Settat-Ben Ahmed sont caractérisés par un réseau hydrographique peu développé. Il est à peine constitué des bouts avals des oueds descendants du plateau. Ces cours d'eau, n'ayant pas d'exutoire vers la mer, ils traversent la plaine de Berrechid sur une dizaine de kilomètres avant de s'y atrophier. Ils sont à écoulement temporaire, leurs eaux arrivent sur la plaine, ils sont ensuite évaporés ou percolent vers la nappe. D'où le fonctionnement endoréique de ce réseau dont la gestion peut contribuer à la recharge du bassin hydrogéologique de la plaine de Berrechid et également limiter les inondations qui touchent de temps en temps la zone situé à l'aval de ce réseau.
Author Keywords: crues, semi-aride, bassin versant.
