Thesis title

Building flood resilient cities through comprehensive Sustainable Urban Drainage Systems (SUDS) planning

Thesis abstract

Urban flooding is an increasing problem influenced by biophysical, demographic, and institutional factors such as climate change, urban growth, changes in land use, and mismanagement of spatial planning. Efforts to develop new measures and strategies in the fight against floods have even changed the concept: From reactive notions as flood defense to resilient approaches as flood risk management (FRM). In the last decades, Sustainable Urban Drainage Systems (SUDS) stand out as efficient FRM tools and have been studied in multiple categories such as performance assessment, cost-benefit analysis, and optimization of design and location. The aim of this research is to contribute substantially to the construction of flood resilient cities quantifying the beneficial impacts of SUDS with a transdisciplinary approach that incorporates hydraulic modeling and stakeholder participation. The first objective is to understand the different mechanisms of community engagement for the integration of SUDS at city scale, and will be addressed through a systematic literature review to identify the different stakeholders' groups, roles, participatory methods, analysis methods, and highlighted barriers in the implementation of those novel techniques. The second objective is to identify SUDS preferences, strengths, means, and barriers of community engagement, private and public sector participation aiming an integrated urban flood risk management in the city of Bogotá, Colombia. Focus Group Discussions and semi-structured interviews, respectively, were selected as data collection methods while the analysis methods include line-by-line coding and AHP (Analytic Hierarchy Process). The third objective is to evaluate the potential of SUDS implementation at sub-basin scale for reducing the risk of pluvial and fluvial flooding. A hydraulic model of SUDS in private and public areas will be conducted using an available tool called PCSWMM (Personal Computer Storm Water Management Model), in order to quantify the volume and peak reduction rates. Since the study will be developed to establish a well-defined work route, the proposed methodology sets a precedent within the agenda of Latin-American cities urban planning, sustainable development, and urban resilience, with the ability to enrich the current global-scale discussion about the effective and successful implementation and planning of SUDS.
