Hypsometrical Approach as a Decision Tool for Rational Management and Planning of Watersheds to Meet Sustainable Development

Abstract

Holistic watershed management strategies are needed to allow making rational development within an entire watershed. This study reports on an integrated watershed approach based on hypsometrical distribution of different quantifiable indicators. The upper part of Ziz watershed at Foum Tillicht gauging station in Morocco is the experimental site for this case study. The research approach used allows an in-depth analysis of future situations; it allows making forecasts based on different socio-economical evolution scenarios. The basic data that needed for this approach include high resolution watershed characterization, e.g., geometry, morphology, geology, soil, and land cover/use. In addition, this work details the field experimental activities conducted within the watershed of interest. There is detailed description of the watershed resources mainly watershed equipment, watershed network for the observation of climate and water resources, hydrology, human activities (agriculture, industry, and urbanization), social and economical aspects, environmental considerations, fauna and flora. Results presented are very useful as a pilot integrated methodology for Morocco.
