Coursework Investigating downstream changes on the Afon Caerfanell INTRODUCTION AIM: To investigate how selected parameters change downstream on the Afon Caerfanell. Hypothesis: 1. The velocity of Afon Caerfanell increases downstream 2. The velocity of the river increases down the stream as the angle of the slope increases. RIVER DEFINITION A river is the natural course of the water‚ which goes from a higher

Besides that‚ the damped rivers also being made as one of the destination for tourism like Tasik Kenyir in Terengganu. The process of constructing the reservoir is being made by damping of a river. We always think that these reservoirs will give us a lot of benefit‚ but how about the negative effect of the existence of this reservoir? Do you know that the construction

Also; the catchment area from which a river system obtains its water. Drainage basin largely ‘closed’ system- watershed – boundary of a water basin- generally follows a ridge of high land.

of a river. (10 Marks) The Bradshaw model is a geographical model that shows us how the characteristics of a river changes between upstream to the downstream. The Bradshaw model allows us to see do the river’s characteristics such as‚ average velocity‚ channel depth‚ load quantity and particle size of the load‚ increases or decreases and how much do they change. However this model can’t be exactly right for all rivers around the world because of the external factors that effects the rivers. Average

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

It is also known as Paseo del Río which is a network of walkways along the banks of the San Antonio River. Today‚ the River Walk is an enormously successful special-case pedestrian street‚ one level down from the automobile street. The River Walk loops under bridges as two parallel sidewalks
