background Upper course The source of the river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most 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

diagrams and annotated photographs. When a river runs over alternating layers of hard and soft rock‚ rapids and waterfalls may form Waterfalls A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends to be low‚ and the river uses much of it’s energy in overcoming friction

a river’s middle and lower courses. In low flow conditions‚ alternating pools and riffles are formed along the river bed. The river channel is deeper in pools so it has greater energy and more erosive power. Energy is lost as the river flows over a riffle because of friction. 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 map below shows the location of Bangladesh and shows the two rivers; the Brahmaputra and the river Ganges running through Bangladesh. In July and august 2007 both Bangladesh and India suffered from severe flooding. Flooding in Bangladesh is a frequent event‚ with it often inundating between 20 and 30% of the country and causing

significant and unexpected events‚ for instance dam breakages. Heavy rainfalls are one of the major causes of floods. The level of water in rivers or lakes rises due to heavy rainfalls. When the level of water rises above the rive banks or dams‚ the water starts overflowing‚ which causes floods. The water overflows to the areas adjoining to the rivers‚ lakes or dams‚ causing floods or deluge. The flood water causes havoc and great destruction in the areas where it flows. Floods occur more in the

what extent do you agree that river landforms can be classified as either erosional or depositional? Many different landforms are made by either deposition or erosion and there are some cases where they can be classified as both. Erosional landforms are caused by erosion which is the breaking down and transportation of particles from one area to another. Depositional landforms are made when particles are deposited somewhere else. In my opinion I think that river landforms can be classified as

were directly affected due to an oil spill which contaminated the river that was their main source of water. Although the dam in Belo Monte is not meant to directly affect the indigenous tribes in a negative way‚ the Indians are still being forced to move due to the redirection of the Xingu river. The river is not only their main source of water‚ but also of food and income. Additionally‚ the redirection the reduces the flow of the river‚ impeding the navigation of riverside and indigenous populations

The courageous lumberjack decided there and then to approach the beast and confront him. The strange "monkey man" quickly fled‚ though‚ as the man approached the river. Upon examining the tracks left behind‚ the lumberjack explained how the prints were almost identical to a human being‚ except for the extremely large size
