IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

On quantification of future tropical cyclone flood hazard under sea-level rise
Author : JENNIFER L. IRISH(1), SCOTT C. HAGEN(2) & MATTHEW BILSKIE(3
It is a near certainty that global sea levels will continue to rise this century (e.g., Stocker 2013), thereby accelerating the tropical-cyclone flooding risk (e.g., Woodruff et al. 2013). In many areas, the complex interactions between storm surge generation and coastal terrain result in nonlinear coupling between surge generation and sea-level rise (e.g., Smith et al.
2010, Bilskie et al. 2014), making summation of existing statistical flood elevation with sea-level rise projections inaccurate. Here, we investigate and compare two approaches for more robust quantification of the future 100-yr return period flood elevation under sea-level rise at Panama City, Florida, USA using the joint probability method with optimal sampling (JPM-OS) (e.g., Resio et al. 2009). In both approaches, we use a small set of seven storms for which highresolution storm surge simulations using ADCIRC coupled with SWAN (e.g., Westerink et al. 2008; Booij et al. 1999) under specific sea-level rise conditions are carried out. These storms are selected because they generate flood elevations near the 100-yr level under present-day conditions.
