geographical issues affecting the area. Human or natural forces can affect geographical issues. One of these issues includes erosion. Erosion is one of the biggest geographical issues‚ which is the wearing down of different materials‚ such as rock‚ soil and sand. Some of the few management strategies used to provide a better environment are sand dunes and the sea bee wall. Erosion is the wearing down of different materials caused by natural forces such as long shore drift‚ waves and tides. These forces

Before looking at river landforms it is important to understand the more general role of rivers and to develop an awareness of the processes at work within rivers. It is through this knowledge that we will better undertand the processes at work in the geomorphology of the drainage basin. The role of rivers can be understood in very simple terms. The river’s role is to balance its load and transport it to the ocean. But this this idea of rivers as merely transporting weathered material to the ocean

An important issue concerning the environment will be critically analyzed by showing the end result of deforestation and soil erosion. Deforestation Occurs when earths’ forests on a massive scale often resulting in damage to the quality of land. A contributing factor that has resulted into deforestation has agriculture as the driving force. According to UNFCCC (2014) secretariat

Have no fear‚ although these things along with natural elements causing erosion of our land‚ there are things that can be done to help slow the effects of overcultivation‚ overgrazing‚ and deforestation and correct these issues which in turn will help save our land for future generations to come.

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.

These cause the river’s flow to become uneven and maximum flow to be concentrated on one side of the river‚ causing lateral erosion on one side‚ creating an outer concave bank. Deposition takes place on the other side of the bend‚ creating a convex bank. The cross-section of a meander is asymmetrical. The outer bank forms a river cliff or a bluff with a deep pool close to the
