SUMMARY:Risk KAN webinar on Compound Extremes
DESCRIPTION:On February 29th\, 3pm UTC (4pm in Germany)\, Risk KAN organise
 s a webinar on Compound Extremes. Avantika Gori\, Assistant Professor of C
 ivil and Environmental Engineering at Rice University will talk about “ 
 the role of climate change and development on hurricane compound hazard ac
 ross spatial scales”. The topic is described as follows:\n\nTropical cyc
 lones (TCs) are one of the largest threats to communities along the US Atl
 antic and Gulf coasts due their extreme winds\, storm surges\, and rainfal
 l. TC hazards coupled with dense urban development along the coastline hav
 e resulted in trillions in US damages over the past several decades\, with
  an increasing trend in losses in recent years. So far\, this trend has be
 en driven mainly by increasing coastal development\, which exposes propert
 y\, assets\, and infrastructure to TC hazards. However\, as the climate co
 ntinues to warm\, sea-level rise and changing TC climatology may also caus
 e large increases in coastal hazard in the future. The links between chang
 ing TC hazards and sea-levels and evolving coastal risk\, as well as the c
 ombined impact of climate change and coastal development\, is still largel
 y unknown. Here\, we quantify and project the magnitude and spatial patter
 n of TC compound risk across the US from wind\, storm surge\, and rainfall
  using statistical-dynamical TC downscaling\, physics-based hazard models\
 , and a county-level statistical damage model trained on historical TC dat
 a. We quantify the spatial distribution of current and future projected TC
  risk under a moderate (SSP2 4.5) emissions scenario. After investigating 
 compound TC risk across the US\, we focus on understanding compound floodi
 ng dynamics under climate change and urban growth in the Cape Fear River E
 stuary\, NC. By coupling various hydrodynamic and hydraulic flood models a
 nd utilizing regional-scale climate and land use projections\, we conduct 
 a sensitivity study of compound flooding to changes in the climatology of 
 storms\, sea-level rise\, and urban growth. We disentangle the relative co
 ntributions to compound flooding from each change factor and quantify thei
 r combined impact through a story-line approach. Our results demonstrate h
 ow climate change and socioeconomic development may cause large shifts in 
 risk and hazard across large and small spatial scales.\n\nYou can find the
  flyer here.\n\nIn addition\, you will find the newsletter Risk KAN: Compo
 und Events for February 2024 here.
