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 point, to the lowest point, usually the sea, ocean, lake or another river. There are few cases where the river simply flows under the ground surface or dries completely before reaching a bigger body of water. The river is also freshwater; there are no rivers with sea water (salty water). Rivers are not always called rivers. Smaller rivers can also be called streams, rills, rivulets and tributaries. Rivers are part of the hydrological cycle. The water inside a river is mainly collected from precipitation (rain) from the drainage basin. The water is also collected from surface runoff, which is caused, by precipitation, groundwater, springs and the melting of natural land (glaciers) and snow. The water in a river is usually confined into a channel and there is usually only one single stream of water within the channel.
VELOCITY DEFINITION
The velocity of a river is t basically the rate of water movement measured in meters per second. In other words it is the speed at which water flows along it.
