Abstract Groundwater availability is one of the key anxieties in most semi-arid regions Ethiopia. The purpose this study was to investigate groundwater potential zone map alluvial plain Gambela. applied analytic hierarchy process (AHP) models with four different machine learning algorithms: random forest classifier (RFC), gradient boosting (GBC), decision tree (DTC), and K-neighbor (KNC). featu...

Conventional wisdom holds that the southern Appalachian Mountains have not experienced a significant phase of tectonic forcing for >200 myr; yet, they share many characteristics with tectonically active settings, including locally high topographic relief, steep slopes, incised river gorges, and frequent mass-wasting events. Two competing hypotheses are commonly used to explain their modern topo...

Landscapes are sometimes argued to be scale-invariant or random surfaces, yet qualitative observations suggest that they contain characteristic spatial scales. We quantitatively investigate the existence of characteristic landscape scales by analyzing two-dimensional Fourier power spectra derived from high-resolution topographic maps of two landscapes in northern California. In both cases, we f...

The Sowie Mountains in the central part of Sudetes range are an under-researched area terms geomorphology, despite their potential representativeness for a large number terrains within Bohemian Massif, built metamorphic bedrock. Apart from providing overview past work, paper summarizes main topographic features massif using visualizations digital terrain model, and outlines wide anthropogenic i...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...
