The Importance of Erosion Control Services | |
Erosion is the natural process that wears away soil, rock and sand. It is what makes a river valley muddy after a rain storm, and why the steep mountains of New Zealand’s fjord country erode so quickly. Several factors impact erosion, including climate, topography and vegetation. Human activities can also impact erosion. For example, farming and the over-grazing of livestock can leave soil vulnerable to erosion. Water Water is the most powerful erosion agent, and is responsible for shaping Earth’s landforms. It erodes rocks by crashing them together, cracking and wearing them down. It also carries and deposits soil particles. It is the force behind river and stream erosion, carving out canyons like the Fish River Canyon in Namibia, for example. Water erosion is especially fast in areas that are bare of plants, such as farm fields after harvest and barren deserts. The intense weather events that cause rainstorms and flash floods can expose topsoil and carry it away. In addition, agricultural runoff of pesticides and fertilizers can wash into natural bodies of water and cause harm to wildlife. A key factor in water erosion is the slope of the land. Gently sloping hills and mountains erode slowly, while steep ones erode more quickly. The size and speed of water flow is also important. The faster the flow, the more soil it can carry away. | |
