Description:

The course focusses on complex understanding of urban drainage and its consequences. The students will master urban hydrology processes of surface runoff formation and transport, transport and transformation processes in sewer system, impacts of urban drainage on surface waters, description of urban drainage performance by monitoring and modelling, innovative technologies and purpose oriented mitigation measures planning and innovation.

1. Urban Drainage - purpose, concept, tasks, integrated approach, tools and methods
2. Waste waters - quantity, quality, data
3. Storm waters - quantity, quality, data
4. Surface runoff processes
5. Transport and transformation processes in sewer system
6. Urban streams - ecosystem of streams, urban drainage impacts, protection strategies)
7. Monitoring and modelling of urban drainage systems
8. Mitigation - end-of-pipe measures (stormwater basins, RTC)
9. Mitigation - storm water management I (principles, selection of storm water recipient, admissibility, feasibility)
10. Mitigation - storm water management II (structures, design, maintenance, examples)
11. Mitigation - decentralized sanitation and re-use (don´t mix strategy, water re-use, nutrients and organic matter re-use, purpose oriented treatment)
12. Climate change adaptive urban planning
13. Summary of lessons learned
