Abstract

The field of study occupies a strategic position in northern Morocco, where it has become an economic and social hub, working on developing natural and human qualifications, revitalizing the economy, facilitating foreign trade, due to its hosting of huge economic projects represented in the Mediterranean ports.Due to its considerable capacities of hosting huge economic projects represented in the Mediterranean ports, the field of study occupies a strategic position in northern Morocco. it has also become an economic and social hub, working on developing natural and human qualifications, revitalizing the economy, and facilitating foreign trade as well.Because of the connection of these Mediterranean ports to the water drainage networks in the region, the morphometric study of the region's basins is of great importance. It enables us to give an image of the shape of the basins and highlight the relationship between their morphological, morphometric, and hydrological characteristics.In order to diagnose this study, geographic information systems were used to calculate a set of morphometric data based on the application of mathematical laws for morphometric analysis.The area of the river basins was 146 km² which is a large extension capable of receiving and collecting large amounts of precipitation. The results showed a variation in the number, lengths, and ranks of the channels, with first and second order channels reaching about 95% of the total number of tributaries. As for the topographic characteristics, the studied river basins were characterized by a weak ruggedness that did not exceed 0.06%.
