Flooding hazard assessment at Tulancingo (Hidalgo, Mexico)

Abstract

In recent decades, the Tulancingo municipality (Mexico), has been affected by numerous extreme weather phenomena that caused heavy flooding events with severe damage to property and people. Most of the weather phenomena placed several dams under hydrologic risk. The hurricane ‘Dean’, in 2007, led to the overflow of the dam ‘La Esperanza’, generating inundations that reached levels of 1 m in Tulancingo. Mexico does not have a specific regulation that establishes critical thresholds for the construction of flooding hazard maps. With the aim to provide a tool for the flooding hazard assessment, we performed a numerical study of inundation waterdepths by means of the IBER software. The study is based on the construction of different inundation scenarios that are based on the hydrologic study of ‘La Esperanza’ dam's basin, associated to regional precipitation and different return periods. Inundation waterdepths, flow velocity, and land use were used to construct flooding hazard maps. We calculated the occurrence probability of the considered inundation events. The hazard maps presented here and the evaluation of the flooding likelihood can support long‐term planning that would help minimise the impact of such events in Tulancingo.

Linking Flood Susceptibility Mapping and Governance in Mexico for Flood Mitigation: A Participatory Approach Model

“…They compared observed and modeled flood frequencies for the period 1970-2010, and found that, recently, the most frequent floods are the result of a rapid and intense deforestation process. Bonasia et al [52] realized a flooding hazard assessment at Tulancingo in the state of Hidalgo. The authors developed a methodology for evaluating downstream flooding probability and associated inundation maps to support long-term mapping and minimize flood impact.…”

“…IBER 2D consta de diferentes módulos: turbulencia, transporte de sedimentos e hidrodinámica, constituyendo este último, la base de la herramienta empleando las ecuaciones de St. Venant 2D de aguas someras resueltas bajo el método de volúmenes finitos y sometidas al principio de conservación de la materia y de momento en las dos direcciones horizontales (Bladé et al, 2014). IBER 2D ha sido empleado en múltiples estudios de hidráulica aplicada: inundaciones fluviales (Bonasia et al, 2017), evaluación de medidas de restauración para pequeños cauces (Castillo et al, 2014), ruptura de represas (Álvarez et al, 2017) y transporte de material leñoso en ríos (Ruiz et al, 2015). Un input importante en IBER es la topografia a través de un MDT.…”
