Search for the waterfalls in Ethiopia using remote sensing data

Waterfalls are specific hydrological and hydrobiological objects that often serve as the natural obstacles for spreading of aquatic animal species, resulting discontinuous range these species. rapids create special habitats riverine organisms cause microclimatic changes along coast. The areas largest waterfalls in Ethiopia, high-mountainous Jinbar Waterfall low-mountainous Blue Nile Falls (Tis Abay,Tis Issat), were considered model. Up-to-date remote sensing GIS processing storing satellite field data makes it possible to identify new rapids, correct supply existing literature cartographic data. ERS obtained from modern Sentinel-2, designed monitor state environment, well radar imagery (SRTM) used mainly. Based on results analysis materials data, localization a number large rivers Ethiopian Highlands was determined parameters selection established. Images with spatial resolution 10–15 m/pixel higher suitable detecting significant (more than 30-m wide). According present study, identifying waterfall zones by methods topographic maps at scale 1:200000 larger, is possible.
