Conference Agenda

Urban runoff is expected to rise as a result of urbanization and the intensification of the hydrological cycle caused by climate change, which could lead to more frequent wastewater spills through combined sewer overflows (CSOs). To this end, cities will need new methodologies and tools that enable the planning of nature-based solutions for urban runoff management towards resilient and sustainable management of urban drainage systems.

In our contribution, we intend to demonstrate our block-level, reduce-data method for managing urban runoff. This method is provided as a modular tool framework comprising of various tools to ease the workflow for setting up urban drainage models. This contribution will focus on the tool’s core functionality, which integrates the spatial discretization of urban blocks with the hydraulic sewer network model, presenting a simplified and innovative approach to managing urban water challenges. Until now, the urban block mapping tool for subcatchment delineation and planning of Low Impact Development has been applied in catchments in France and Germany. As for the sewer network modelling component of the tool, we have developed a Python package for generating synthetic sewer network layouts called pysewer.
