The Water Erosion Prediction Project (WEPP) model is a physically based erosion simulation model built on the fundamentals of hydrology, plant science, hydraulics, and erosion mechanics. [ 1 ] [ 2 ] The model was developed by an interagency team of scientists to replace the Universal Soil Loss Equation (USLE) and has been widely used in the ...
The Sphinx water erosion hypothesis is a fringe claim, contending that the Great Sphinx of Giza and its enclosing walls show erosion consistent with precipitation. Its proponents believe this dates the construction of the Sphinx to Predynastic Egypt or earlier.
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Some erosion models are purely statistical, others more mechanistic (or physically based). Two of the more widely used soil erosion models in North America are the Revised Universal Soil Loss Equation (RUSLE) and the Water Erosion Prediction Project erosion model (WEPP).
This project was born out of the request for assistance made by President Goodluck Ebele Jonathan to World Bank in 2010. He requested for assistance in tackling severe gully erosion in Southern Nigeria, land degradation in Northern Nigeria and environmental insecurity. [2] [3] The project is being monitored by the Federal Ministry of Environment.
LOCAL COOPERATION, STUDY; REPORT TO CONGRESS Pub. L. 93-251, title I, Sec. 24, Mar. 7, 1974, 88 Stat. 20, provided that the Secretary of the Army make a study of the items of local cooperation involving hold and save harmless provisions which have been required for water resource development projects under his jurisdiction and report on such study to Congress not later than June 30, 1975.
For starters, the town must manage beach erosion, plan for rising sea levels, secure a reliable source for potable fresh water, and prepare for a potential major hurricane disaster.
In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolian) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. [1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of ...
