Ignite Talks - TPM Resilience Lab

Short abstract

Climate change is likely to increase the frequency and intensity of flooding. Transportation infrastructure is vulnerable to extreme precipitation because it is typically designed using frequency, duration, and intensity relationships that do not represent future climate. Understanding of how future climate can disrupt transportation is important to enhance the resilience of cities and urban areas. This presentation proposes evaluating flood impacts on urban areas and the transportation infrastructure with the Hydrologic-Footprint-Residence (HFR) metric. The HFR represents the dynamics of the inundation area and its duration.  To illustrate this new metric, the hydrodynamic models were used. These metrics were estimated for the transportation infrastructure of San Antonio, Texas, for 24-h 100- and 500-year storms for representative concentration pathway (RCP) 4.5 and 8.5 scenarios. Results show that climate change will increase flood impacts in the city. The new metrics presented a larger relative increase with climate change when compared to traditional metrics, such as maximum flooded areas. This study highlights the importance of using duration components to evaluate flood impacts on transportation infrastructure.

We will start with a short talk followed by ample time to dive deeper based on your questions. For the ones who will be there physically we have some drinks and snack waiting for you!

This is a hybrid event. You can join us online through zoom.

You can also come and meet us in person. We have limited spaces, so please contact us if you are joining us on site (M.Q.Gaanderse-1@tudelft.nl).

Our physical location is :
TU Delft, Faculty of Technology, Policy and Management (TPM), Jaffalaan 5, 2628 BX Delft, B3.470
