Description

Water is the most important agent in shaping the landscape. It is responsible for weathering, soil formation, the erosion of sediment from hill slopes, gullies and river banks, and the transport and deposition of sediment in channels, on floodplains and in estuaries. Water also acts beneath the surface, replenishing groundwater systems and triggering environmental problems like soil salinity. This course provides students with a comprehensive introduction to the movement of water through river basins, and the role water plays in the development of soils and the flux of sediments through the landscape. Through a series of lectures, laboratories and field work, students will learn how to quantify the movement of water through various components of the hydrological cycle, and the major factors controlling the way in which water moulds the river basin landscape.

Learning outcomes

On successful completion of the course students will be able to:

1. Explain the movement of water through the river basin, from the point of rainfall to discharge at the coast;

2. Explain how soils form and evolve, and the principles and procedures for soil classification;

3. Differentiate and explain the processes that shape the major components of the river basin, including hillslopes, river channels and Differentiate and explain the processes that shape the major components of the river basin, including hillslopes, river channels and floodplains, aquifers and estuaries;

4. Identify, explain and interpret sediment yields and the delivery of sediments from upland environments to estuaries.

5. Identify and measure hydrological and geomorphological processes through the use of field and laboratory instrumentation, and computer software;

6. Interpret mapping and aerial photograph interpretation;

7. Demonstrate enhanced questioning, field observation, deduction and report writing skills.
