Three Major Causes of Soil Erosion Amanda Brown Environmental Science 136 Rainfall and runoff is a water erosion problem also known as splash erosion. This is the first stage in the erosion process. The impact of rainfall drops on the soil surface can break down soil aggregates as the impact of falling raindrops breaks up the topsoil. This erosion is caused by long lasting and less intense storms. Runoff can occur whenever there is excess water on a slope that can’t be absorbed into the soil or

measures are not taken. The result can be unnaturally high concentrations of some chemicals‚ such as arsenic‚ sulfuric acid‚ and mercury over a significant area of surface or subsurface. Runoff of mere soil or rock debris -although non-toxic- also devastates the surrounding vegetation. The dumping of the runoff in surface waters or in forests is the worst option here. Submarine tailings disposal is regarded as a better option (if the soil is pumped to a great depth) Mere land storage and refilling

What is gully erosion? Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started‚ gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance. Repair work done in the early stages of newly formed gullies is easier and more economical than letting the problem go unchecked for too long. Large gullies are difficult and costly to repair. What causes gully erosion ? Gully erosion occurs

DRAINAGE SYSTEM DESIGN Objective: The drainage system for the project functions to ensure effective transportation of storm water in order to avert the occurrence of flooding of the site. It also helps to safely discharge grey wastewater from buildings to their end points. NATURE OF SITE‚ LOCATION AND TOPOGRAPHY: The sight‚ predominantly sandy‚ slopes to the south-western part. Due to this topography‚ water flows to the southern part of the community and since there are insufficient drains to collect
