CSE420. Technical Hydrology - Flood Control Works (ects: 5)

The course aims to help students understand and use basic concepts to analyze rainfall data and to calculate hydrological parameters for the rational management of water resources, assessment of flood discharges, selection of appropriate flood protection measures, design of river, stream and torrent bed alterations, and the design and control of flood protection works, reservoirs and hydrodynamic projects
