MODELLING THE EFFECT OF VEGETATION COVER AND. Soil erosion in clayey, subsurface drained agricultural fields in Finland can cause problems due to the export of suspended sediment and sediment-bound nutrients into nearby waterways. Suspended sediment is transported from the field via two main hydrological pathways: 1) surface runoff and 2) preferential flow in macropores to subsurface drains.

    1. Introduction. Soil erosion is a severe environmental issue. It causes both on-site soil and nutrient losses in agricultural lands and off-site water pollution, lake and reservoir sedimentation, and channel and harbor silting (Ferguson, 1986, Gardner and Kjerfve, 2006, Zhang et al., 2013, Ma et al., 2014, Fang, 2015). 13/11/2012 · Soil erosion by water has substantial on-site as well as off-site effects.

It has also deteriorated the water quality and caused negative effects on the aquatic ecosystem. The Imha reservoir was affected by sediment-laden density currents during The role of erosion by water in the UK is considered. A summary of available data describing water erosion is presented providing insights into rates of erosion from the hillslope scale to the large catchment scale. Evidence suggests that soil erosion rates in excess of acceptable thresholds occur on a wide range of soils and under a wide range
