Precipitaciones extremas y sus implicaciones en procesos de remoción en masa en la planificación urbana de Tampico, México

Abstract

The study analyzed the frequency and exposure of extreme precipitations and their implica tions for assessment and zoning of mass movement processes in the Tampico city, located in the lower river basin Pánuco, Mexico. The methodology employs a Geographic Information System for the aggregation of hydrometeorological and geomorphological data, making the analysis of spatio-temporal variations of extreme precipitations, and their implications for assessment and zoning of mass movement processes, necessary for urban planning in Tampico. The results indicate that the distribution of extreme precipitations favors the high aggressiveness climatic, which determines the soil erosion processes and geomorphic hazards such as falls and debris flows in the study area. Also in the coming years is expected to increase the mass movement processes related to environmental factors, for the increased occurrence and intensity of extreme precipitations, and to human factors, for the growth of population and dwellings exposed to areas unstable.
