AB: A flooding hazard study was realized 2004-2006 through technical cooperation of Japan International Cooperation Agency (JICA) with INETER, upon the request of the Government of Nicaragua. The resulting hazard map shows the inundated area for a 200 years return period flood in a small riverbasin (65 square kilometers) near the Nicaraguan Pacific Coast. This area is affected by heavy rainfall induced by tropical storms in the Caribbean Sea and the Pacific Ocean. The map results from a study performed by a Nicaraguan-Japanese team that developed a flood hazard approach for a small river basin with scarce hydrometeorological data to be replicated to other basins. The team elaborated 25, 50,100 and 200 year return period flood hydrographs to be applied to a bidimensional mathematic model. The simulation results were transformed into a cartographic map using GIS. The map was handed out to Central, Departmental and Municipal authorities for their use.
