Coastal Flooding

Coastal Flooding

What is the water level reached once every 100 years on a beach? How many hours per yeardoes the supratidal zone of an estuary become flooded?

To answer these questions, IH Cantabria has developed methodologies, databases, statistics and numerical tools to determine the flood risk on the coast due to the joint action of marine dynamics (waves, wind, tidal), river and tsunamis.

IH Cantabria has extensive experience in Spain (having been awarded the National Environmental Prize in 1998 for the "Atlas of the Spanish Coast Flood") in statistical evaluations and downscaling of quantified statistical models.  The researchers at IH Cantabria have conducted numerous studies for consulting firms and different governments over the last 20 years. Recently, IH Cantabria has concluded the coastal high spatial resolution Flood Atlas for Spain and Brazil using 60 years of tidal wave and weather reanalysis databases.

DATE: 2009-2012

CLIENT: AECID. Spanish Agency for International Development Cooperation, Ministry of Brazil do Meio Ambiente and Ministry of Planning, Brazil Orçamento e Gestão

TASKS: Developing a flood Atlas and the generation of a database for reanalysis along the Brazilian coast, validated with satellite and tide gauge data. The study helped determine the sea level for any point on the coast and the flood level (run-up) on  beaches along the Brazilian coast. This work is part of the international cooperation project (SMC-Brazil), which aims to improve technological transfer of the Coastal Modelling System (SMC) and its adaptation to the Brazilian coast.
