Comparative morphometric analysis of Ermenek river basin and Gökçay basin in terms of basin prioritization
Abstract
In the study, the morphometric parameters of Ermenek River Basin (ERB) and Gökçay Basin (GB) have been analyzed, as comparatively aim to contribute to the prioritization of the watersheds in terms of natural resource management. In the study, 23 parameters, including linear, areal, and relief morphometries were calculated. The data infrastructure of the research was created by using the Digital Elevation Model (DEM) obtained from ALOS PALSAR (Advanced Land Observing Satellite-1, Phased Array type L-band Synthetic Aperture Radar Mission) satellite images with a resolution of 12.5 m in determining the stream streams used in the analysis, the Strahler method was taken into account, and the measurements were made using the ArcMap 10.4.1 program. According to the results based on parameter calculations, the ratio of ERB to GB; impermeable (Rb, RL, Fs, If, Re, Rn), circular (Lum, lo, T, Ff, Rc, Kg), high slope value (H, Rh, Rhp, Rn), geomorphologically closer to old age (Hc, Hi), and also indirectly determined to be a basin with high flood sensitivity and erosion susceptibility. According to the data obtained, it has been understood that ERB has a higher priority than GB in terms of natural resource management due to these potential problems in the soil and water resources.
