Abstract
The Kenitra city located in western of Morocco. It is a port on the Sbu river, has a population in 2014 of 431,282. This city has known a rapid growth in the number of inhabitants due to the migration of the surrounding villages, as well as the growth of a group of industrial activities, as this city is the third economic city in Morocco, as it contains the third industrial zone in Morocco, this region follows the activity of car factories. Given its social and economic importance, protecting it from flood risks is a priority for decision-makers. In this paper, we developed a hydrological model using HEC-HMS tools for the purpose of protecting human life and economic activities from the risk of floods. The forecast model has been used in order to identify and regions at risk from flooding and to take other precautions to protect life. Additionally, a forecast can provide the basis for preparing critical infrastructure for floods in order to minimize damage.
Highlights
The mathematical model in hydrology can give a set of responses that can be submitted for observation as a representation of the phenomenon being examined
Experts [15] have advocated for a shift from structural flood protection to non-structural flood protection measures in flood-prone areas that are already occupied, such as land use management and flood forecasting, among other things
The delimitation of the Kenitra watershed, the calculation of its geometric and topographic properties, the orientation of the slopes and the altitude ranges, as well as the hydrographic network are extracted from a model. digital terrain (DEM)
Summary
The mathematical model in hydrology can give a set of responses that can be submitted for observation as a representation of the phenomenon being examined. Experts [15] have advocated for a shift from structural flood protection to non-structural flood protection measures in flood-prone areas that are already occupied, such as land use management and flood forecasting, among other things This paradigm change is inextricably linked to advances in atmospheric and earth surface instruments and remote sensing, as well as natural disaster predictions. The purpose of this study is flood modeling in the zone, the work makes it possible to deal with the risk of flooding, a hydrological study with the aim of intervening at different levels It allows the evaluation of structural measures which consist in the realization of the installations and works of protection against the floods. For each of the processes that may be involved in the formation of floods at the outlet of a given watershed, it is a matter of making a choice of model adapted to the specific runoff conditions of the area studied
