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

All 44 rivers in Kerala are highly polluted due to inflow of untreated domestic‚ industrial wastes and agriculture runoff. Most of the industries are near the thickly populated riversides‚ often near cities and towns. There is no efficient water treatment system in industries and city municipalities. Pollution level in some of the sites is far above permissible limits. Close proximity of increasing numbers of leach pit latrines under varying soil conditions‚ late rite (midland) and sandy soils

Also‚ when the river floods it leaves behind fertile silt. write about how soils‚ vegetation and climate influence surface runoff which influences flooding or water shortage in the stupid drainage basin.. 1. Flood - Like droughts‚ flood are a naturally occurring phenomenon. Flooding is a result of a temporary overflow of water that escapes its usual boundaries. While small-scale

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

al Explain four different forms of global pollution that may arise from a construction project and explain four key methods used to protect the natural environment against such pollutants Environmental Pollution Construction Sites Construction sites are found both within urban and rural areas‚ often in the close proximity of homes. Due to their proximity to homes and the materials used‚ construction sites may generate home pollution. This involves air‚ water‚ soil‚ and/or noise pollution. Additionally

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a
