Floods in a changing climate
The modeling of coastal flooding due to tropical cyclones (TCs) is a challenge involvingmeteorologists, oceanographers, coastal engineers and hydrologists. Each element (wind, sea levelpressure, waves, surge, tide, response of coastal defences, run-off, river discharges) can be addressedwith a different degree of complexity, regarding the physical processes involved and the spatialresolution. A key issue is to balance the different components, obtaining an efficient, robust andmanageable method composed by a number of numerical and empirical models capable of being appliedfor the reconstruction of past TCs and also for the synthetic generation of possible TCs. In this work, wepropose a method based on the combination of a suite of atmospheric, hydrologic and hydrodynamicmodels. The methodology is applied to evaluate the coastal flooding associated to TC Gonu (June 2007)in Muscat (Oman), validating the results obtained qualitatively (pictures, satellite imagery) andquantitatively (buoys, tidal gauges).
