The Universal Soil Loss Equation (USLE) and revised USLE (RUSLE) are often used to estimate soil erosion at regional landscape scales, however a major limitation is the difficulty in extracting the LS factor. The geographic information system-based (GIS-based) methods which have been developed for estimating the LS factor for USLE and RUSLE also have limitations. The unit contributing area-base...

nesar anticline is located in west of country and in north of kermanshah province. pattern of drainage network at each district is under the effect of various factors which has intensive anomaly in nesar anticline in spite of its low area and this in turn reflects different lithology, tectonic effects and slope changes in anticline. the goal of this research is the recognition of influential fa...

[1] We investigate numerically the evolution of crustal and lithospheric thickness, thermal structure, topography, and strain rate of the Tibetan Plateau through time, using the thin viscous sheet approach. We show that lithospheric mantle must have been removed from beneath Tibet to explain the present surface elevation and lack of regional surface slope. In the absence of this removal, the mo...

While topography can infer erosion potential, the practice of conventional agronomic management trigger accelerated and pose major threats to soil assets such as biodiversity. The majority farmlands in Upper-Eastern Ghana are moderately hilly highly susceptible erosion. This study pioneered comparative interactive effects versus conservation agriculture practices (reduced tillage, main crop cov...

[1] Slope streaks on Mars represent a currently active geological process. Various theories for slope streak formation have suggested that slope streaks form by disturbing only a thin surface veneer, or by staining of the surface, preserving pre-existing topography within the streak. Theories also vary as to whether the formation mechanism requires the presence of water or another liquid. We pr...

Introduction: Mars Orbiter Laser Altimeter (MOLA) onboard Mars Global Surveyor (MGS) spacecraft produced a large homogeneous data set of precise elevation measurements along MGS tracks [1]. We have used this data set to map and study statistical characteristics of kilometerand subkilometer-scale topography [e.g., 2, 3]. In the present work we use MOLA data set to map and study slope asymmetry o...

Near the continental shelf break in the southern Weddell Sea, Warm Deep Water and Western Shelf Water meet. Mixing mechanisms, such as internal tides, have the potential to mix these water masses and form Antarctic Bottom Water. A modified version of the Princeton Ocean Model was utilized to investigate the internal tidal fields generated by the interaction of the M2 barotropic tide with topogr...

Topographic decorrelation due to the local surface slope has been an obstacle to interferometric synthetic aperture radar (InSAR) applications. A modified spatial decorrelation function is derived as a function of the baseline and topography. This function explains the origin of the total topographic decorrelation phenomenon on the slopes directly facing radar illumination and layover, which ma...
