Investigating storm surge risk to three Sri Lankan coastal communities June 21,2019   |  Source: EurekAlert

An international team of engineers is joining forces with a disaster educationalist to investigate coastal flooding due to cyclones in three communities within the northern and eastern provinces of Sri Lanka.

Communities in these provinces face a significantly greater risk of flooding from storm surges associated with seasonal cyclones than those in the rest of the country's coastal belt.

Using a range of methods including computer modelling, researchers plan to develop a series of compound flood hazard maps that will take into account storm surge components, rainfall and the future impact of climate change.

The C-FLOOD (Compound flooding from tropical cyclone-induced sea surge and precipitation in Sri Lanka) project is being funded through a grant from the Natural Environment Research Council (NERC) and the UK's Department for International Development under the SHEAR Catalyst programme.

It builds upon the previous work of national storm surge flood hazard assessment conducted by the University of Peradeniya and the Coast Conservation Department for Sri Lanka's Ministry of Disaster Management. This work produced storm surge flood hazard maps for the entire coastline of Sri Lanka. However, these maps did not include the effect of precipitation. This new C-FLOOD
