Abstract

The prioritization of watersheds has increasingly become an optimal and relevant approach for the management and planning against natural hazards. This approach is based on the morphometric analysis of the watersheds according to some parameters and indicators. In this study, we adopted this approach using Geographic Information System (GIS) techniques to identify the priority sub-watersheds of the Inaouene River upstream of the Idris I dam. This watershed, which is part of the Sebou watershed with an area of approximately 3608.2 km², is made of up 38 sub-watersheds and an area of gulleys. The results showed that 57.89% of the Inaouene River’s sub-watersheds have high to very high priority. The most important ones are Lahdar, El Melah 1, Gherghab, Larbaâ, and Mezwarou watersheds. By unveiling the distinctive morphometric characteristics of the watershed, this study enhances our understanding of its hydrological behavior, while providing crucial data to support soil and water conservation measures. This ensures sustainable agriculture, preserves water quality, and prevents sedimentation in the Idris I dam.

利用地理信息系统（GIS）技术对伊德里斯一号大坝上游的伊纳乌内河分流域进行形态分析和优先排序

确定流域的优先次序已日益成为管理和规划自然灾害的最佳和相关方法。这种方法的基础是根据一些参数和指标对流域进行形态分析。在本研究中，我们采用了这种方法，利用地理信息系统（GIS）技术来确定伊德里斯一号大坝上游伊纳乌内河的优先次级流域。该流域是塞布流域的一部分，面积约 3608.2 平方公里，由 38 个子流域和一片沟谷组成。调查结果显示，伊纳乌内河 57.89% 的次级流域具有高度或极高度优先性。其中最重要的是 Lahdar、El Melah 1、Gherghab、Larbaâ 和 Mezwarou 流域。这项研究通过揭示流域的独特形态特征，加深了我们对其水文行为的了解，同时为支持水土保持措施提供了重要数据。这确保了农业的可持续发展，保护了水质，并防止了伊德里斯一号大坝的沉积。

期刊介绍： Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences. The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
