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

of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing as most of its energy is used overcoming the friction of the large angular bedload. The bedload is large and angular as it hasn’t been subjected too much erosion.

litter‚ and use of the land surrounding these areas. One issue that is stated above is the happening of erosion on the sand dunes and rocks on the coastline of Terrigal and Wamberal. Some people have caused more pressure on these areas as they have built housing such as at Stop 7‚ “The Ruins” Wamberal South. Many of the people that lived on the beach have tried to find ways to stop most of the erosion from waves and wind affecting their land and housing. On the beach we saw many strategies that are effective

Michigan is full of rivers and lakes‚ but it is most importantly known for its great lakes‚ making Michigan the “Mitten State.” That being said‚ it is no surprise that water has a large effect on the state‚ shaping the land with the erosion and deposition that occurs with lakes and rivers‚ to the glacial movement a million years ago. How has water shaped the mitten shape of Michigan not only today‚ but also during the glaciers of the Ice Age? The glaciers that covered Michigan over one

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

discovered that Coastal Management along the beach is required. To manage the coast we must be aware of the effect of human activity‚ erosion and decaying of the sand dunes as they destroy the beach but the Council has helped prevent these issues. One of the main issues is erosion; erosion is the process of wearing something down due to the action of water and wind. If erosion goes left unattended‚ the beach size will reduce as more will be damaged. The Sutherland Shire council has helped this problem

EVS-1001 Everest University Online Individual Work Week 5 Soil erosion has become a serious problem for many ecosystems. Erosion occurs when the soil and hummus particles are removed from their location by wind and water (Wright & Boorse‚ 2014). This process causes the soil to erode and become ‘barren” and exposed to the elements (Wright & Boorse‚ 2014‚ p. 276). There are three major contributing factors to soil erosion: overgrazing‚ over cultivation‚ and deforestation. The purpose of
