Can green roofs help with stormwater floods?

The short answer would be “not without widespread application” and “not alone”.

“ order to reduce the impact of climate change, we need extraordinary measures and big paradigm shifts, rather than small and incremental changes (Hölscher et al., 2018)”

In our new paper, we investigated the effect of implementing #greenroofs on reducing stormwater runoff to provide evidence-based knowledge to guide decision-makers and stakeholders. You can read our findings here.

Resilience for All

World Urban Forum, Poland | TU Delft, Training Event 

30th June, 9 am – 11:45 am

Supriya Krishnan and I are organizing a transdisciplinary workshop titled ‘Resilience for All’ at the UN-Habitat’s World Urban Forum (WUF) to be held in Poland between 26 – 30 June. Established in 2001 by the United Nations, WUF is the premier global conference on sustainable urbanization that examines one of the world’s most pressing issues today: rapid urbanization and its impact on communities, cities, economies, climate change, and policies.

‘Resilience for All’ is the official event selected from TU Delft and brings together nine speakers from the Faculty of Technology, Policy and Management, and the Faculty of Architecture. The session is officially supported by TU Delft’s Global Urban Lab, TPM’s AI Lab, and TPM’s Center for Urban Science and Policy.

The session is designed as a workshop-style training event to present scientific planning support tools and methods at the intersection of two themes: Equitable Futures and Urban Resilience. The aim is to identify gaps in implementing the latest techniques in decision-making to inform inclusive policies to mitigate urban inequality and build resilience. Session participants will learn from design-driven and data-driven tools and methods applied to real case studies for evidence-based planning to manage resilience and promote equity in spatially explicit ways.

Speakers include Dr. Roberto Rocco, Dr. Claudiu Forgaci, Dr. Carissa Champlin, Dr. Trivik Verma, Dr. Juliana Goncalves, Dr. Ylenia Casali, Mikhail Sirenko, Dr. Nazli Aydin (co-organizer) and Supriya Krishnan (co-organizer).

IEEE International Forum on Smart Grids for Smart Cities

I am very happy to be invited to IEEE International Forum on Smart Grids for Smart Cities: #AI for #SmartCities. I will talk about methods, case studies, and experiment-based analysis for transportation and water networks #resilience on March 22.

An overview of critical infrastructure resilience: Methods, case studies and experiment-based analysis for transportation and water networks resilience

Critical infrastructures are the backbones of cities for sustaining the quality of life. Urbanisation, population, and climate change-related disasters have been increasing at an unprecedented rate that managing functionality of critical infrastructures or providing continuous services become more and more challenging. Addressing urban resilience by developing recovery strategies and providing solutions for those emerging disruptions are a matter of urgency. While various resilience and performance loss assessment approaches have been emerging for water, energy, and transportation networks, there is not yet a consolidated method/view on how to evaluate resilience. In this talk, I will give an overview of the resilience of critical infrastructures including methods, case studies, experiment-based resilience analysis for transportation and water networks. 

Publication on water network resilience

Our latest publication on water distribution system resilience and recovery is out. We present a recovery function and evaluate the performance of the water distribution system under different disruption scenarios. The paper is published in Journal of Water Resources Planning and Management.

Week of Resilience at TU Delft

179th DIES NATALIS: Week of Resilience. A week in which we celebrate Resilience with knowledge & inspiration.

I talk about managing the recovery and resilience of road networks under seismic hazards. How can you visualise that for decision makers? Check out the video here.
