Abstract
This research aims at discovering the potential of Landsat imagery for obtaining geomorphological information and its relationship with drought phenomena. The method used for this study is quantitative through the interpretation and examination of aspects of morphometry and morpho-structure-passive interpretation. Concerning the Landsat imaging using composite methods, sharpening and using DEM. The results showed that Landsat 8 imagery was able to provide very detailed information by showing that composite imagery combined with HSV fusion affirmation provides an affirmation of the upper limit of appearance. Moreover, DEM information may contain topographic information and a morpho-passive structure state in the area. This combination is able to provide information on the appearance of landforms such as; structural landforms, solutional landforms, karst landforms, volcanic landforms, marine landforms, and fluvial landforms. Based on the results of the interpretation and field surveys, it can be concluded that areas with structural and karst landforms are experiencing faster drought than other areas in the Gerokgak sub-region.
