Numerical Simulation of the Flood Occurred in Acapulco, Mexico, Because of Two Extreme Hydrometeorological Phenomena Simultaneously

Due to its geographical location, Mexico is exposed to extreme weather events., such as tropical cyclones in the Atlantic and Pacific Ocean in addition to cold fronts from North America. On September 15 and 16, 2013, Hurricane Manuel hit the coasts of Guerreo, Colima, Jalisco, Nayarit and Oaxaca states; Furthermore, on 13, 14, 15 and 16 of the same month, Hurricane Ingrid struck on the coasts of Veracruz, Tamaulipas and Tabasco states. as a result, in the state of Guerrero rainfall of great magnitude, intensity and duration occurred and caused severe flooding in Acapulco, Guerrero and other cities of the same state leaving material damages valued at 3,950 million dollars, 200,000 victims. and 157 deceased.

The hydrological measurements of Ingrind and Manuel eventes were made and information is available on precipitation, hydrographs, use and type surfaces and flood levels of the study area. In order to know the spatial and temporal variation of the precipitation, the behavior of the hydraulic variables in the flood and the danger to which the exposed population was subjected, in this work, it is reproduced numerically with a two-dimensional model of free use, first the flood occurred due to the presence of these hydrometeorological phenomena and subsequently the performance of the proposed hydraulic works.
