CIVL34001 Hydraulics 3 10 Semester 1 Undergraduate Level 3 David Apsley Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Last part of a Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 The behaviour of flows with a free surface affects the design of many civil engineering structures including weirs, spillways, man-made channels, coastal defences such as breakwaters and offshore structures such as pontoons, and platforms for oil & gas and renewable energy applications. This unit introduces the principles governing the behaviour of free-surface flows: specifically, open-channel flow and waves. Standard models are developed to model the main types of flow to predict surface level, velocities and pressures and to estimate structure loading.The intended learning outcomes are focused on understanding the equations governing the behaviour of the different types of open channel flow and of wave motion so that these can be applied to practical engineering problems.
