Urban Water Systems Modelling (WSE/HI/10B/e)

Basic knowledge of hydrology and hydraulics

On completion of this module the participants are able to

1. Understand the complexity of urban water systems, and the interactions of their different components. Asset management and optimisation of systems.
2. Understand the structure, service provided and failures of the service for a) urban water distribution, b) wastewater drainage networks and c). wastewater treatment plants
3. Know how to model these systems and to have used a typical modelling product (EPANET,  MOUSE/SWMM and WEST++)
4. Describe how to use the models to assess the performance of the systems
5. Understand the processes controlling the water quality of the receiving waters from urban drainage effluents.
6. Know how to model water quality processes in sewer/drainage systems and impacts on receiving waters with a typical modelling product (MOUSE, MIKE 11, MIKE21, SWMM)
