This study used the GIS and RS-based approach for a reservoir analysis, a case of the Maibalyk water reservoir in Nur-Sultan, the capital city of the
Republic of Kazakhstan, to investigate the geomorphological characteristics of the reservoir and their potential to flood events. The reservoir is one of the potential recreational sites in Nur-Sultan. The Storage Capacity tool in conjunction with Digital Elevation Model (DEM) was used to compute water-surface elevations and corresponding storage capacities in the ArcGIS 10.5 software package. The input boundary polygon was extracted using Google Earth Pro images. The state of land use/land cover around the reservoir was also successfully derived from Landsat images. More low-lying areas (flood zones) were observed in the North and West of the reservoir compared to the South and East of the reservoir.
