This introduction is going to be about rivers and how they shape the landscape.

   Rivers are an important thing to study because the study of rivers can help to build up the knowledge and understanding of places for ‘the location of places and environments’, for ‘to describe where places are’ i.e. near a river, ‘to identify how and why places change’. Regarding their knowledge and understanding of patterns and processes’ names, the example of river erosion as a physical process that ‘can cause change in places and environments’. People also need a basic understanding flooding. They need to know factors that lead to a flooding disaster such as heavy rainfall, vegetation cover, rock type, seasonal change, previous weather etc. It is important for people to know these factors so that they can predict and know in such conditions of a flood disaster about to occur and undertake measures either to help prevent the flood or prevent the disasters and damages the river may cause. Disasters that may be caused by floods include loss of bridges, loss of money, loss of farmland, loss of industry, death etc.  

   People also need to know about rivers; their effects on landscapes, the physical features of rivers and the processes of erosion and deposition that affect them’. It is expected that people gain an understanding of environmental damage and environmental improvement and in the pollution of a river and the effects of this on ‘the future quality of people’s lives’. Some people would like to know the processes responsible for the development of selected landforms and the role of rock type and weathering’, and the ‘causes and effects of a related hazard (flooding or landslides) and human responses to it’. 

 People also need to understand the uses of rivers. They can be as a source of water supply, the production of hydro-electric power and a place that hosts leisure activities that people like doing such as fishing, rowing etc.  Rivers are also used as major transport systems and market routes e.g. the Mississippi in North America.

   I expect the size of the river channel to increase as we go downstream. Near the source of a river, you will expect it to be in an upland area with a narrow channel. It would have large boulders and large angular bedload which will, therefore, result in it being a rough channel.

   Factors that I expect to help the stream increase are tributaries that will bring more water and discharge it into the river, increasing not only its channel but velocity of the river as well. Tributaries also bring more bedload into the main river ...
