ABSTRACT: Water management in
morocco faces significant challenges in both levels, quality and quantity, in
order to address these challenges and to secure the rational and efficient
management of water resources, it is necessary to try to understand the
different issues involved in the water cycle works! The large number of
hydrological studies and techniques used at the Sebou watershed are limited to
water quality, and the use of the simpler empirical models, that, do not permit
to take into consideration all the factors affecting flow and cycle of water.
In the purpose of using the hydrological model SWAT to study the hydrological
functioning of the Sebou watershed (Morocco) which faces many problems
regarding the management of its water resources like all the other watersheds
in our country, this study focuses on the creation, organization and generation
of input data (soil, soil occupation, climate…) using a GIS (ARCGIS) then, the
configuration and calibration of the model and after that, the evaluation of
the results. The main reason behind this work is to measure the adaptability of
this model to the selected area in order to generalize the model to the whole
Sebou watershed. The results are satisfying; they show that this model can
represent the overall hydrological regime of the pilot basin Bab-Merzouka. This
model can open up new perspectives regarding the effects of climate change, and
the changes caused by humans on water resources, in terms of both quantity and
quality.
