La inundación de octubre de 1879 en el Bajo Segura. Magnitud y efectos inducidos

Abstract

This article constitutes a approach in the analysis of the catastrophic flood occurred on October 1875 in the Guadalentin Basin and Lower Segura river. In first place, event implications within scientist, political and socioeconomic contexts areis described, as well as the magnitude of the same, valued in terms of material damages and morphological effects. Next the physical factors that contributes to the disaster are studied, revising the pluviométric and hydrological data and deducing another new (kinetic energy of the rain, rainfall erosivity, hydraulic parameters for the methods of Manning and MEI). Finally the situation of the basin in relation to the risk is shown, emphasizing the effects derived of the works of defense and other civil structures like an clear indicator of the environmental fragility imposed for the human action.
