Summary of Content

The impacts of development on the hydrological cycle and implications for water resource management will be explored. Methods of urban stormwater management will be introduced that will include storm rainfall estimation, runoff assessment, surface water sewer and open channel design. Microdrainage software will be applied to explore pipe networks, open channel, source control and sustainable urban drainage systems (SUDS). Methods to assess small rural catchment runoff will be introduced and the management of runoff within the planning process and current guidance. The group project assessment will apply these methods to an urban drainage design problem. River flood estimation and catchment flood management will be introduced backed up by river channel hydraulics and the use of Flood modeller software for river modelling. The software will be used to develop a 1-D river model to determine flood levels and risk under climate change scenarios. River restoration methods will be explored using the model(s) for analysis and design. The project assessment will assess flood risk to a development with design options. Water resources for supply will explore options for intakes, storage and distribution.

Teaching / Learning Strategy

Teaching will be an equal split of lectures and computing practical/tutorial classes in lecture-practical, lecture-practical sessions. Practical classes will consist of computer sessions and/or site visits. Learning and teaching strategies will be developed and implemented, appropriate to student needs, to enable all students to participate fully in the module. Case studies will be introduced during lectures.
