The availability, accessibility and quality of data are significant obstacles to hydrological modelling. Estimating the initial values model´’ ’s parameters is a laborious determining task requiring much attention. Geographic information systems (GIS) spatial remote sensing prometting tools for processing collecting data. In this work, we use an innovative approach estimate HEC-HMS model from s...

Soil degradation is a global phenomenon affecting the productivity of agricultural land. Due to low vegetation cover and aggressive climate, Morocco presents significant case soil through erosion desertification. The Ouergha catchment highly vulnerable this scourge. objective study was assess sensitivity land in area. MEDALUS approach, widely used Mediterranean region, soils degradation/deserti...

Understanding the spatiotemporal distribution of past and future climate change impact is essential for effective water resource management. This study aims to reveal temperature precipitation on hydrological streamflow Ouergha watershed inflow regime Al Wahda dam. Initially, historical trend was assessed using Mann Kendall tests Sen’s slope. Then, regional Climate Models (Cordex-Africa) were u...

The objective of this study is the elaboration a rainfall-runoff model capable predicting future floods resulting from extreme rainfall events in rugged Moroccan Mediterranean basin with marly lands. integration deterministic hydrological modelling system, Hydrologic Engineering Center-Hydrologic Modelling System, Geographic Information System was employed to construct model. calibration and va...

In this paper, we attempted to review the erosion in Ouergha watershed by applying two spatial approaches. The has an area of around 7300 km² representing approximately 18.2% Sebou basin which it is main tributary. order develop map using SWAT model, was important prepare a large database describing proprieties, furthermore, daily hydro-climatic data. This model integrates MUSLE equation for es...

The objective of this work is the realization of a map spatialising proposals of management and planning of lands, with a view to their rational management within the framework of a sustainable development. It was based on a diagnosis of the natural environment that allowed the analysis and identification of constraints to the development of the watershed of Ouergha (North of MOROCCO). The meth...
