Quantifying resilience of water infrastructure to extreme precipitation events in urban areas

The India-UK Water Centre (IUKWC) promotes cooperation and collaboration between the complementary priorities of NERC-MoES water security research. This report outlines the activities carried out during a Researcher Exchange by Ms Chandra Rupa of the Indian Institute of Science, Bangalore hosted by Prof. Guangtao Fu, University of Exeter, UK. Quantifying uncertainties in short duration high intensity precipitation, which often causes heavy flooding in urban areas, is crucial as well as challenging. In addition, assessing risk, vulnerability and resilience of urban water infrastructure as a result of heavy precipitation events is equally important for supporting long-term planning and management decisions. However, extreme precipitation, vulnerability and resilience are all influenced by a wide range of factors, including climate change and socio-economic development. Therefore, this Researcher Exchange programme aimed to gain an enhanced understanding of extreme precipitation uncertainty and quantifying the risk, vulnerability and resilience of urban water infrastructure to flooding. The applicability is demonstrated through a pilot case study in Bangalore, India.
