Identifying Suitable Dam Sites Using Geospatial Data and Machine Learning: A Case Study of the Katsina-Ala River in Benue State, Nigeria" explores the integration of geospatial data and machine learning techniques to locate optimal sites for dam construction along the Katsina-Ala River. # Identifying Suitable Dam Sites Using Geospatial Data and Machine Learning ## Overview This study presents a comprehensive approach to identifying optimal dam sites along the Katsina-Ala River in Benue State, Nigeria, by integrating **Geospatial Data** and **Machine Learning** with Multi-Criteria Decision Analysis (MCDA). The methodology combines advanced geospatial analysis tools, machine learning algorithms, and the Analytic Hierarchy Process (AHP) to determine suitable locations for dam infrastructure. ## Objective The primary goal of this study is to develop a **robust decision-making tool** for selecting suitable dam sites based on environmental, topographic, and hydrological criteria, ensuring sustainable water resource management and infrastructure development. --- ## Key Features - **Data Integration:** Utilization of diverse geospatial datasets: - **Shuttle Radar Topography Mission (SRTM) DEM** for elevation and slope data. - **Sentinel-2 Imagery** for land use/land cover classification. - **General Bathymetric Chart of the Oceans (GEBCO)** for bathymetric insights. - **Historical Rainfall Data** for hydrological analysis. - **Multi-Criteria Decision Analysis (MCDA):** Assigning weights to suitability criteria using the **Analytic Hierarchy Process (AHP)**. - **Machine Learning:** Validation of suitability results using the **Support Vector Machine (SVM)** classifier. - **Geospatial Analysis Tools:** Use of **ArcGIS 10.5** and Python-based machine learning algorithms. --- ## Methodology The approach integrates the following steps: 1. **Data Acquisition:** Collection of geospatial data (DEM, Sentinel-2 imagery, GEBCO, and rainfall data). 2. **Pre-Processing:** Preparing and analyzing datasets in ArcGIS and Python environments. 3. **Criteria Selection:** Identification of influencing factors: - **Elevation** - **Stream Order** - **Slope** - **Distance from Stream** - **Land Use/Land Cover (LULC)** - **Rainfall** - **Soil** - **Geology** 4. **Weight Ass …
