Taihu Lake is located at the center of Changjiang delta region, the Lake and its effluent rivers are important water sources for 40 million around inhabitants and rapidly increasing industrial factories in Shanghai, Jiangsu and Zhejiang. The pollutants originate mainly from acidy rain, home sewage of the vast number of inhabitants, livestock manure, agricultural fertilizers & pesticides applied...

Composted municipal solid wastes (CMSW) could potentially be used as a mulching material to control runoff and soil erosion. The effects of mulching with CMSW on water percolation and rate of compost decomposition were studied using laboratory rainfall simulator. Samples of typical loess soil (Calcic Haploxeralf) were packed in boxes and either covered with 0, 100,200 and 300 m' ha-' of CMSW, o...

Dirnberger, J. M. and J. Weinberger. 2005. Influences of lake level changes on reservoir water clarity in Allatoona Lake, Georgia. Lake and Reserv. Manage. Vol. 21(1):24-29. In Allatoona Lake (Georgia USA), secchi transparency (measured every 2 to 4 weeks during a Phase I U.S. EPA Clean Lakes Study) was typically 5to 8fold greater in summer than late autumn and winter. The intensity of storms i...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...

[1] Soil erosion models are usually limited in their application to the field scale; however, the management of land resources requires information at the regional scale. Large‐scale physically based land surface schemes (LSS) provide estimates of regional scale hydrologic processes that contribute to erosion. If scaling issues are adequately addressed, coupling an LSS to a physically based ero...

these advantages will not be fully recognized unless the spatial and temporal predictability of process-based Spatially averaged soil erosion data provide little information on models are validated. Thus, spatially distributed erosion soil erosion dynamics. Dynamically varied, spatially distributed erosion data are needed to better understand erosion processes and data are of great importance i...

ity in rainfall erosivity and associated sediment yield. Rainfall erosivity and sediment yield can be measured Rainfall depth within small semiarid watersheds can have high much more cost effectively than runoff, an important spatial variability, but spatial variability in rainfall erosivity, a more direct determinant of sediment yield, has not been quantified. Using consideration when studying...

A simple modeling and laboratory investigation was carried out to investigate the raindrop effects on both sediment detachment and chemical transport from soil–water into runoff. Solute movement between soil–water and runoff is usually modeled as either a mixing model or as a diffusion-like process, both of which ignore the important roles of raindrop impact on the transport process. We hypothe...

The surroundings of Corigliano and Rossano (NE Calabria) were damaged by a short-lasting localized rainstorm on 12 August 2015, when more than 230 mm rain in sixteen hours caused damage exceeding 100 million euros. In the Map, shallow landslides triggered event are shown at 1:50,000 scale, together with areas affected soil erosion flooding, most sites; historical also mapped. main slope-stabili...
