Course Aim: To introduce hydraulic structures used in water resources development and management, coastal zone management and harbors, and to provide knowledge on selection and design of hydraulic structures.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    explain the purposes of different types of hydraulic structures and recommend appropriate structures for a given application based on technical, economic and environmental feasibility.

➢    conduct hydraulic analysis and design appropriate structural components of hydraulic structures.

➢    appraise the safety and sustainable aspects of hydraulic structures.

Course Content:

➢    Dams and outlet works: Loads on dams, dam types and their components, dam site selection, environmental impacts, design flood, spillways, intake structures, sluices, gates and valves, fish passes, energy dissipators, dam instrumentation, dam monitoring and safety, reservoir sedimentation and sediment management, dam strengthening, village tanks in Sri Lanka, rehabilitation of village tanks, radial gate design, earth dam design, ogee spillway profile design, stilling basin design.

➢    Diversion and water conveyance structures: Types of water conveyance systems (tunnels, canals, flumes, pipes) and their components, cross drainage structures (siphons, aqueducts, level crossings), design of flow measuring structures, design of transitions and drop structures, irrigation distribution systems, design of turn-outs and distribution canals.

➢    Storm water drainage: Urban storm water drainage systems, sustainable urban drainage solutions/modelling, culverts design.

➢    Coastal and harbor structures: Design of a revetment, design of an off-shore breakwater, design of vertical structures.
