Rivers coursework conclusion

An increase in cross-sectional area means that the river is becoming wider and deeper. A smaller proportion of the water in the river is in contact with the bed and banks. This means that less energy is lost to friction, so the water has more kinetic energy and can move faster.

However, as the river continues downstream there is less substrate on the bed which means that there less energy waste on friction. This means that there is more energy to erode the bed. Hypothesis 3- Gradient will decrease as you move from source to mouth. Gradient is the elevation of the river along its course.

For example, try to link results for width, depth and wetted perimeter with results for gradient. If you have used secondary data, try to link this to the primary data that you collected. Make sure you mention the evidence from your results that backs up each conclusion.
