a) Describe the main feauture of flow on the Trinity River before and after the construction of the dam. (4)
Before the construction of the dam discharge reaches over 500 cumecs at peak times which occur early on in the calender year . However this value decreases to almost 0 for the rest of the year until the late December, early january period. After construction of the dam this value, as we would assume, has plummeted to roughly 0-5 all year around which peak in October
b) Explain how damn construction may alter fluvial processes operating in a river system (4)
Dams may affect the process of deposition of alluvium, for example in the case of the three gorges dam, alluvium that should ...view middle of the document...
Why differing land uses may conflict in river basins.
There are an array of diverse land uses which exist in and around river basins. These may include industry, recreation, agriculture, residential and tourist functions.
However a major conflict is that between industry and recreation. Industry may use the river as a waste removal facility whilst recreational users may use the river for things such as water sports or perhaps as a visual pleasure. The disposal of waste in the river removes the ability for the recreational users to do these kind of things and hence a conflict arises, swimmers will no longer be able to swim and fishermen will perhaps not longer be able to catch fish as most if not all may die due to harmful waste in their habitat.
Agricultural use as well as residential may also have a conflict in that of land. Land around the river basin would be of high demand for farmers due to the fertile soil and water being readily available for the irrigation process. However, land will also be demanded for those residential users. Land for building new homes as well as gardens. This creates a conflict as land that is owned by say the farmer can't be built on by people to build homes. Land which is used as a garden...
