Academic Year 2018/2019

Learning outcomes

The course provides advanced theoretical basis, knowledge of the tools and applied skills for: (1) the design of large scale wastewater systems, with particular emphasis on sewer systems and water supply systems for large cities; (2) the design of large dams, with particular emphasis on the estimation of the forcings, the design of dam's hydraulic facilities, the prevention and detection of leakage, and the design of large scale power plants. Student gain expertise on the hydraulic and management challenges of large scale infrastructures and their environmental impact. Case studies related to large scale sewer systems and recently built large scale dams are considered and provide the way forward through the learning of the concepts.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of basic hydraulics, hydrology is required to attend with profit this course. Advanced Hydrosystem Engineering (or any similar courses about Water Supply and Urban Drainage) is a preferential pre-requisite.

Fluent spoken and written English is a necessary pre-requisite: all lectures and tutorials, and all study material will be in English.
