The objective of this study is to model the hydrology in the Sidi Jabeur basin, located in Bouregreg watershed at the north-central of Morocco, using the spatially distributed model (ATHYS) in order to understand and determine the different watershed hydrological processes. The study requires the collection of a series of data as inputs models namely rainfall data, water quantity, soil occupation, digital terrain model and requires also a calibration in order to evaluate the model in validation phase. The simulation results are obtained from the validation phase aim to replicate the operation of Sidi Jabeur watershed, and present a suitable adjustment perspective of the observed hydrograph. These results show that the objective is achieved and a model distributed like ATHYS plays an effective role in improving the efficiency and presents a high advantage in anticipation of runoff volume.

The article presents more specifically how the stormwater management builds the overall plan and the problems that can be encountered during the implementation of improvements. With the growing waterproofing of cities and activity zones, the long rains or heavy rain storms, causing downstream flooding problems (or locally) as well as any shortfall in groundwater recharge underlying and disrupt the capacity of treatment plants and exceeds that of unit drainage systems of water, sustainable drainage system are tested in different countries. Better management and control of urban discharges during rainy weather is necessary, designing a alternative and integrated management model based on ecological engineering techniques, themselves adding value to natural purification and water filtration capacity allows not having to continually increase the capacity of the sewer systems, pipes and retention ponds hard, which are sources of technical, property, financial, environmental, social, legal, security and future maintenance costs.
