- Résumé :
This study estimates water volume variations in the Fontaine des Gazelles Dam in the province of Biskra using high-, medium-, and low-resolution digital elevation models (DEMs). The water surface was extracted using NDWI, and the volume of storage was obtained using the water elevation and spatial analysis. The results obtained in comparison with Peng equation show that there exists a significant change in the water surface. This represents a decrease of more than 29 hm3 between 2005 and 2020, on which precipitations were found to be the main factor of these changes. For validation purposes, NRMSE and MAPE were used. Respectively, with values of 1.30% and 1.50% for Alos Palsar, 8.10% and 8.70% for SRTM1, and 8.20% and 10.10% for SRTM3, it is clear that Alos Palsar performs much better results. This leads us to conclude that Alos Palsar is the most reliable to be adopted in studies related to water volume variations.
