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. Modeling. to Facilitate Sustainable Land Management Decisions. A Presentation By: Brent D. . Fogleman. In partial fulfillment of the requirements for the . degreee. of Master of. Geospatial Information Science and Technology. Anticipated Problem: . What is soil erosion?. I. . Soil erosion . is the process by which soil is moved. When soil is eroded, it may become pollution in the water or air. The land where it came from, loses fertility. Vegetation and other coverings help prevent soil erosion. . Chapter 7. Section 7.1 Weathering. Weathering is the process by which rocks on or near Earth’s surface break down and change. . Erosion is the removal and transport of weathered material from one location to another.. Antony . Lenehan. Remote Sewerage Treatment and Effluent Disposal. Site and soil.

Rill erosion. is the erosion by running water in small channels. , on the side of a slope.. 2) . Gully erosion. is when a rill channel evolves to become deep and wide.. . (“Flow-Assisted”. . or “Flow-Accelerated”. . Corrosion). An increase in corrosion brought about by a high relative velocity between the corrosive environment and the surface.. Removal of the metal may be:. What Is An . Ecoregion. ?. Ecoregion. - . a major ecosystem with distinctive geography, characteristic plants and animals, ecosystems, and receiving uniform solar radiation and moisture . Sometimes called an ecological region or bioregion. WHAT IS COASTAL EROSION? Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage. Human activities, like construction, dredging, CO THK JAIN COLLEGE. WHAT IS SOIL EROSION. . Soil erosion is a type of soil degradation in which there is wearing away or displacement of the upper layer of soil (topsoil).. Soil erosion is a global threat in the current world scenario.. On a notecard:. Identify units of erosion measurement in Figure A. Convert the average erosion rate into mm/yr.. Figure A: Determine which regions in the United States have the highest continental erosion rates . weathering and erosion. The process of weathering and erosion are the main forces behind landscape types. . However, they are not the only reason for a plain, plateau, or a mountain region to form. . Soils. Precipitation.
