Dam engineering
Summary
Dams are paramount for human development around the world. The course is an introduction to the fascinating domain of dam engineering, from design to construction, for water storage and regulated supply, including for renewable energy generation (hydropower), flood protection and drought prevention.
Content
- Purposes of dams and reservoirs. Potential positive and negative impacts on the environment.
- Types of dams. Selection criteria for the selection of the type of dam.
- Concrete dams: design criteria. Calculations of forces and stresses in gravity dams,
buttress dams and arch dams. Behaviour during earthquakes. Constructive details. Particular foundations and uplift pressures. Drainage and foundation treatment. Specification of mass concrete: construction methods and heating effects. - Construction alternatives: roller compacted concrete, hardfill (embankment), cyclopean concrete
- Dam monitoring. Security concept and risk management. Equipment for auscultation.
- Embankment dams (earth and rock): typical profiles and selection criteria.
- Foundation treatment.
- Stability calculations.
- Earthquake behaviour. Controls during execution and operation. Surface protection.
- Layout of dam and appurtenant structures (flood release system, bottom outlets, water intakes, powerhouse, river diversion system, etc.)
- Emergency Planning
- Innovation in Dam Engineeerig
