Soil labile organic carbon (LOC) is a valuable and sensitive parameter of the changes in soil (C) pools further affects structural stability. However, influences soil-aggregate stability on LOC fractions under erosion conditions are still unclear, especially collapsing gully area south China. Soils five positions erosion, including upper catchment (UC), wall (CW), colluvial deposit (CD), scour ...

Introduction: The discovery of gullies on Mars [1,2] resulted in a wide variety of proposed candidate mechanisms for formation but ensuing analyses have shown very strong latitude and orientation dependencies on their distributions [3-6]. These constraints have been interpreted to require: 1) a volatile on or near the surface as a source of liquid water, and 2) insolation and slope orientation ...

Introduction: Martian gullies are defined by [1] to be slope features comprised of an upslope alcove, a midslope channel, and a downslope depositional fan. Due to their relative youth and similarities to waterrelated features on Earth, the Martian gullies have attracted much attention since their discovery by the Mars Orbiter Camera [1]. Many erosional agents for the gullies have been proposed ...

Abstract Gully mapping techniques successfully identify gullies over a large range of breadths and depths in complex landscapes but practices for estimating gully volumes need further development. gap-interpolation estimation volume does not often factor landscape microtopography the generation new surface. These approaches can thus overestimate classical volumes, averaging depressions, or unde...

Gullies are landforms with specific patterns of shape, topography, hydrology, vegetation, and soil characteristics. Remote sensing products (TanDEM-X, Sentinel-1, Sentinel-2) serve as inputs into an iterative algorithm, initialized using a micro-mapping simulation training data, to map gullies in the northwestern Namibia. A Random Forest Classifier examines pixels similar characteristics pool u...
