Coastal areas can be protected from the effects of natural processes‚ for example the effects of erosion‚ deposition‚ transportation‚ weathering and mass movement. The most problematic of these is erosion. There are three types of erosion: hydraulic action‚ abrasion and attrition which all contribute together to erode cliffs‚ causing the coastline to be vulnerable and weaker. The cause of erosion can then lead to mass movement for example rock fall and slumping which can affect the coastline greatly

Abstract Nigeria has a total land area of 983‚213 km2 occupied by about 140 Million people: The interaction of these millions of people with their environment has left indelible mark on the landscape. Deforestation‚ desertification‚ flooding‚ erosion and all kinds of pollution as well as climate change are some of the resultant effects of man’s interaction with his environment. These changes occur as the people attempt to acquire their seemingly endless desire for food‚ shelter‚ recreation and

particles (sand‚ silt and clay). DESCRIPTION OF DESPERSIVE CLAY SOILS Initially‚ clay soils were thought to be highly resistant to erosion from the flow water‚ lately it has been found that highly erodible clay soils exist in nature. Some natural clay soils disperse in the presence of relatively pure water and are highly susceptible to erosion. The tendency for dispersive erosion in a given soil depends on variables such as mineralogy and chemistry of the clay‚ as well as dissolved salts in the water in

degradation occurs (e.g. erosion) and off site where sediments are deposited. However‚ the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption of improved technology and have led some to question the negative effects of desertification. The relative magnitude of economic losses due to productivity decline versus environmental deterioration also has created a debate. Some economists argue that the on-site impact of soil erosion and other degradative

fast-flowing water that has torn bridges’ foundations apart. The Northern communities are worried their houses will one day become a victim. If their homes are destroyed‚ where will they go? Unfortunately‚ land erosion is already instigating major environmental troubles. In one case‚ erosion not only washed out a bridge but also obstructed the route of a sewage-removal truck. As a result‚ “the community was forced to dump its sewage into the sea‚” (Healey et al 294). It should be noted that if the

ADVANTAGES OF BLACK SAND MINING : Sand has become a very important mineral for our society due to its many uses. It can be used for making concrete‚ filling roads‚ building sites‚ brick-making‚ making glass‚ sandpapers‚ reclamations‚ and etc. The advantage of black sand mining is that the black sand is the one of the raw materials that used in making a metal that we used in building different establishments and buildings and also our houses. Aside from that ‚ families that is near in the black

little water in the river giving it less energy to change the depth of the channel by erosion. As you go downstream the volume/amount of water (also known as discharge) also increases because more and more tributaries join the main river. The increase of water makes the energy levels rise when theres moe energy there is more erosion (in the form of abrasion‚ attrition and hydraulic action). these types of erosion erode away at the river bed creating a deeper channel. Whilst the depth varies downstream

majority of people have come to know this term; deforestation is the clear cutting or total removal of trees in a forest. With the destruction of these luscious and plentiful forests come many environmental issues ranging from global warming to soil erosion to loss of habitat. By the end of this report you should have a better understanding of the impact of deforestation and what has to be done in Canada ’s Boreal Shield (ecozone) and of that on the Pacific Coast. The clear cutting of forests has existed
