Predicting runoff and erosion from watersheds burned by wildfires requires an understanding of the spatial structure of both hillslope and channel drainage networks. We investigate the small-scale and large-scale structures of drainage networks using field studies and computer analysis of 30-m digital elevation model. Topologic variables were derived from a composite 30-m DEM, which included 14...

In recent years, as the frequency of debris flow outbreak in strong earthquake areas has increased and scale been expanding, order to explore erosion characteristics flow, a lateral flume model experimental device designed, 18 groups incomplete orthogonal experiments have carried out, with unit weight 1.6~2.0 g/cm3, content fine particles accumulation 0~28.82%, longitudinal slope gradient gully...

The study and mapping of evidences soil piping using non-destructive techniques is a key issue in quantitative geomorphology. This paper attempts to combine Aerial systems (Unmanned Vehicles (UAV)), physical chemical attributes, near-surface geophysical survey tools (ground penetrating radar electrical resistivity tomography) provide comprehensive understanding geometric features arid semi-arid...

Gully erosion is the most important water erosion which causes land degradation and imbalance in lands. Land degradation, broken ecological balance of landscapes and sensitive condition of biological resources are among reasons of gully erosion study. This study performed with the goal of determining the topographical threshold of gully erosion and expansion and also predicting sensitive areas ...

The formation process for Martian gullies is a critical unknown understanding recent climate conditions. Leading hypotheses include by snowmelt in past climate, or via currently active CO2 frost processes. This paper presents an expanded catalog of >300 flows gullies. results indicate that sediment transport current gully moves the full range materials needed formation. New are more likely to b...

This study aims at the detection of gully-affected areas by applying object-based image analysis in the region of Taroudannt, Morocco, which is highly affected by gully erosion while simultaneously representing a major region of agro-industry with a high demand of arable land. As high-resolution optical satellite data are readily available from various sensors and with a much better temporal re...

A gully is an excavation cut in the immediate footwall or hangingwall of the reef for the purpose of enabling the removal of rock from the face or providing access to the face for mining personnel or material1. The gully sidewalls and hangingwall often pose a serious stability problem in the gold and platinum mines in South Africa, since records of fatal rock-related injuries show that they are...
