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...

map by air photo-interpretation and field checks of one full profile and 10 to 30 augerings per 1000 ha; the mostly compound map units refer to the sub-types of the CYS , which is a six-level hierarchy influenced by earlier European systems; keys and class descriptions are mostly qua litative; a lso, 10 800 geo-referenced profile descriptions with standard laboratory data were recorded. All pol...

The greatest obstacle to soil erosion modelling at larger spatial scales is the lack of data on soil characteristics. One key parameter for modelling soil erosion is the soil erodibility, expressed as the K-factor in the widely used soil erosion model, the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). The K-factor, which expresses the susceptibility of a soil to erode, is...

An experiment was performed to study non-target effects of difenoconazole (fungicide), deltamethrin (insecticide) and ethofumesate (herbicide) on microbial parameters in a clay-loam soil. Pesticides were applied as commercial formulations to soil samples at different concentrations (5, 50 and 500 mg kg(-1) DW soil) and then incubated under laboratory conditions for 3 months. Throughout the incu...

Soil labile organic carbon and soil enzymes play important roles in the carbon cycle of coastal wetlands that have high organic carbon accumulation rates. Soils under three vegetations (Phragmites australis, Spartina alterniflora, and Scirpusm mariqueter) as well as bare mudflat in Hangzhou Bay wetland of China were collected seasonally. Seasonal dynamics and correlations of soil labile organic...
