THT303 Analysis and design of systems for urban drainage

The course includes methods for analysis, planning and design of urban drainage systems. The course is divided into three sections:

1. Transport systems for wastewater: System understanding, functional requirements and legislation, efficiency, discharge of pollution via overflows and leaks, risk of flooding and inflow/infiltration, measurement data and measurement technology.
2. Runoff modelling: Precipitation-runoff models, terrain analyses, precipitation statistics, extreme value statistics and frequency analysis, climate change, infiltration and other catchment processes, groundwater, analysis of uncertainty and sensitivity, calibration and validation of models, simulations with design storms and continuous time series.
3. Urban stormwater management: Stormwater in legislation, regulations, application of the three-step strategy, analysis and design of nature-based solutions, calculations of production, dispersion and removal of stormwater contaminants, flow control and detention/retention, floodways, hydraulic surface modeling and erosion, added values ​​and multi-objective optimization.

Relevant analysis tools: SCALGO Live, SWMM, HEC-RAS 2D, Python, R, Excel

Machine learning methods: NSGA-ii, GODE, ANN

Compulsory assignments associated with the three modules will give the students a good introduction to the analysis tools.
