PPT-Modeling the impact of vegetation changes on erosion rates

Jon D Pelletier University of Arizona Hillslopefluvia l geomorphologists have often taken climate change to be synonymous with changes in runoffdischargeprecipitation ie driving shear stresses . Methods of soil conservation (ch3). The key aspects discussed in this chapter are:. Windbreaks. Contour ploughing. Stubble planting. Terraces. Stone walls. Reduce farming in dry weather. Windbreaks. Reforestation. OR. Control of margin dynamics by sediments, part 4: erosion and transport. Alex Densmore. Department of Geography & Institute of Hazard, Risk and Resilience. Durham University. Sanjeev discussed sedimentary basins as bathtubs that evolve and fill over geological time scales, and (importantly) preserve a record of the detritus from margin evolution. Rwenzori.
