Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
Grassed waterway in Velm, Belgium, during a sunny day. A grassed waterway is a 2-metre (6.6 ft) to 48-metre-wide (157 ft) native grassland strip of green belt.It is generally installed in the thalweg, the deepest continuous line along a valley or watercourse, of a cultivated dry valley in order to control erosion.
Gully erosion can progress through a variety and combination of processes. The erosion processes include incision and bank erosion by water flow, mass movement of saturated or unsaturated bank or wall material, groundwater seepage - sapping the overlying material, collapse of soil pipes or tunnels in dispersive soils, or a combination of these ...
The board approved the project on May 8, 2012. It commenced operation on September 16, 2013, with the appointment of Amos Abu, Ruth Jane Kennedy-Walker, and Grant Milne as team leaders, the Federal Ministry of Environment as the implementing agency, and a total project cost of US$650 million and committed amount of World Bank of US$500 million.
No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain.
Gully erosion occurs when runoff water accumulates and rapidly flows in narrow channels during or immediately after heavy rains or melting snow, removing soil to a considerable depth. [12] [13] [14] Another cause of gully erosion is grazing, which often results in ground compaction. Because the soil is exposed, it loses the ability to absorb ...
“This plant, if not managed, can take over and kill many other plants, even large trees. The Virginia Creeper is a good option that can cover an area and climb trees without presenting a threat ...
Eroded hilltops due to tillage erosion. Tillage erosion is a form of soil erosion occurring in cultivated fields due to the movement of soil by tillage. [1] [2] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [3] [4] [5] A signature ...
