Accumulation rates of terrestrial sediment have increased in the past few million years both on and adjacent to continents, although not everywhere. Apparently, erosion has increased in elevated terrain regardless of when last tectonically active or what the present-day climate. In many regions, sediment coarsened abruptly in late Pliocene time. Sparser data suggest increased sedimentation rate...

After wildfires, land managers must assess the potential for increased flooding, erosion, and sedimentation, and the increased threat these effects may pose to people, structures, and valued resources. A Web-based Erosion Risk Management Tool (ERMiT) has been developed to predict surface erosion from postfire hillslopes, and to evaluate the potential effectiveness of various erosion mitigation ...

Estimation of sediment transport load due to erosion in river basins is one of the issues which is indispensable for many projects related to water resources, soil and damps construction. With regards to the phenomenon of erosion and transmission Sedimentation in rivers has always led to deformation in the seaboard and sedimentation, so the management and planning in bank of rivers is important...

determining the relative sensitivity of land to erosion and its factors, could be the basis of soil conservation programs. the aim of this study is to compare water and wind erosion functions in land degradation of dasht-e-jeihoon using psiac and irifr.ea models and the source studying of aeolian sediments in geomorphologic facieses as homogeneous units. the results indicate that in dasht-e-jei...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

Environmental 137Cs adsorbed on fine sediments has many uses as a tracer in erosion and sedimentation studies. The determination of sedimentation rates in lakes and reservoirs using 137Cs as a geochronological marker is described in detail. From a survey of literature sources it is shown that 137Cs levels in soils and sediments can be a powerful tool for the identification and quantification of...
