Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The Mediterranean environment is characterized by strong temporal variations in rainfall volume and intensity, soil moisture and vegetation cover along the year. These factors play a key role on soil erosion. The aim of this work is to ide...

Bedrock erodibility exerts a fundamental control on fluvial incision, and therefore the evolution of entire landscapes. However, roles relative significance specific bedrock properties like rock strength discontinuity spacing in setting remain poorly understood. As result, is often overlooked or oversimplified numerical field-based investigations landscape processes, leading to misinterpretatio...

The most common methods used to evaluate the potential hydraulic erosion of rock are index-based methods, which correlate force flowing water and capacity a resist erosion. This is evaluated using erodibility indices, combine set specific geological parameters. Nonetheless, there exists no clear consensus in regard relative importance assigned Our study proposes (i) review existing (ii) method ...

The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...
