Abstract: Dam site selection and stability assessment are critical steps in water resource management and infrastructure development. The integration of remote sensing technologies provides a non-invasive, efficient, and comprehensive approach to identify suitable dam locations and evaluate their geological and environmental stability. This paper reviews various remote sensing techniques, including multispectral and hyperspectral satellite imagery, Digital Elevation Models (DEM), Synthetic Aperture Radar (SAR), and Geographic Information Systems (GIS), utilized in the assessment of dam sites. The methodologies incorporate land use/land cover analysis, terrain slope evaluation, geological fault detection, soil moisture assessment, and sedimentation monitoring. A case study example is provided to illustrate the application of these techniques. A detailed table summarizes the key parameters analyzed through remote sensing for dam site evaluation. Limitations and future prospects of remote sensing in dam engineering are also discussed. The findings highlight how remote sensing enhances traditional geotechnical methods, supporting sustainable and safe dam construction.
