introduction: soil erosion by water is one of the most important processes of land degradation, especially in semi-arid areas. among different types of the soil erosion, gully erosion accounts as one of the most critical processes which can cause soil destruction, changes in landscape and water resources filling of reservoir of dams,decrease in water transport capacity of rivers and agricultura...

The south-west coast of the Isle of Wight (see Figure 4.1 for general location) is geomorphologically rich in features of interest. It contains examples of most of the cliff types undergoing active erosion described from other GCR sites. The site demonstrates well how coastal processes have produced different cliff forms related not only to variations of lithology and geological structure, but ...

18 Many dryland areas are being converted into intensively managed irrigation crops, what 19 can disrupt the hydrological regime, degrade soil and water quality, enhance siltation, 20 erosion and bank instability, and affect biological communities. Still, the impacts of 21 irrigation schemes on the functioning of terrestrial and aquatic ecosystems are poorly 22 understood. Here we assess the ef...

Soil erosion has become a serious problem in recent decades due to unhalted trends of unsustainable land use practices. Assessment of soil erosion is a prominent tool in planning and conservation of soil and water resource ecosystems. The Universal Soil Loss Equation (USLE) was applied to Nyabarongo River Catchment that drains about 8413.75 km² (33%) of the total Rwanda coverage and a small par...

The environmental characteristics of many artificial gamma-emitting radionuclides provide a number of distinct advantages over other forms of fine-sediment tracer that are readily exploitable when undertaking erosion investigations. This makes them particularly effective for accurately measuring the movement of small quantities of fine-sediment, especially in low-energy environments where soil ...
