upper course and lower course of a river. This coursework is underpinned through some key processes/concepts. These are: Dishcharge‚ velocity‚ lateral erosio‚ Bed load and vertical erosoin. Discharge- The discharge of a river is the volume of water which flows through it in a given time. Velocity - The velocity of a river is the speed at which water flows along it. Lateral erosion- Lateral erosion in a river is the wearing away of the sides of the river which makes the channel deeper because

located on the confluences of the river Ganges and Brahmaputra these are two very large rivers which meet in Bangladesh. Causes: The Bangladesh flood is a result of both physical and human factors because: Topography: Bangladesh has a low height above sea level which is approximately 2-8m. This means that as the sea level rises more water will be closer to the surface and its 140 million people live mainly on the flood plains of the river Ganges‚ Brahmaputra and Meghna

There are two common approaches to solve the flood problem which is the structural and

A river changes as you move from the source to the mouth (downstream)‚ but also from bank to bank (across stream). In this essay I will be discussing how depth velocity and bedload size change downstream and across stream linking to past river theory (the Bradshaw method). Depth is defined as the distance between the surface of the river to the bottom (the river bed) this distance is measured in a straight vertical line. As you move from the source to the mouth the river depth increases. (which

because water cannot flow up that surface. These are known as “watershed divides”. An example of a watershed is the Etobicoke River Watershed. Streams of water flow downward‚ to form larger streams of water‚ which will eventually lead into the Etobicoke River. The Etobicoke River would then lead into Lake Ontario‚ which would lead the water through the St. Lawrence River‚ opening into the Atlantic Ocean. Everything is in a watershed‚ even your house
