Evaluate the evidence for human impacts on downstream flood risk in rural catchments in temperate regions. Before we can evaluate human impacts on flood risk we must first establish what is meant by temperate regions and also rural catchments. Temperate regions are generally regarded as lying between the Tropic of Cancer and the Arctic Circle or the Tropic of Capricorn and the Antarctic Circle and therefore rivers investigated in this essay will fall within these parameters. Rural catchments are

1.0 ABSTRACT The purpose of the impact of jet experiment is to design a system to determine the force generated by the impact of jet on a variety of target vanes. A formula is given to calculate the reaction force at the different vanes caused by the jet. At the end of the experiment‚ the data collected and results calculated will then be compared to theoretical values which are given. Students are expected to be able to come to a conclusion regarding the relationship between the reaction force
