Appurtenant Safety Structures for Dams and Hydraulic Circuits
Academic Year 2023/24
CR053 course is part of 1 study plan
N-P-C-SI (N) / V Winter Semester 2nd year
The course provides students with information on the safety assessment of the water works during floods. N-year flows in the profile of the dam determining, design discharge, transfer the flood waves and its transforming through the reservoir. The use of emergency spillways and bottom outlets of dams for controlled transfer of flood waves. Converting of the control flood waves. The design of the emergency spillways, spaces of stilling basins and spillway channel for safe operation during floods. Designing of the multipurpose flow control structure of small dams and polder dams. Function and Designing of the surge tank of the hydropower plant. Water hammer exclusion of the direct impact in long pipelines and pumping stations circuits.
