Determination of hazard and vulnerability to the occurrence of flooding by heavy rains on the railway lines of the central area of the havana railway knot, Havana, Cuba

Abstract

Rail transport in Cuba has suffered effects as a result of the occurrence
of floods by heavy rains in the railroads, repeatedly
disrupts its function and cause losses, so, it is necessary to count
with information that satisfies the need to predict this threat. The
investigation determined the intensity of flood hazard identification
by intense rainfall for return periods of between 5 and 100
years in the area Central of the knot railway from Havana. Based
on these results the susceptible railroads appreciated to this danger,
which were detected visually in a rising field of analyzing
parameters such as quality, presence of drainage systems and
the need to repair medium or light, so maintenance, as well as
literature reviews. These results were mapped, pondering the
value depending on analyst. The sum of these elements established
a characterization by types of the vulnerability of the
railways. Research facilitates the knowledge necessary to carry
out the relevant actions in any emergency, in addition to the
consolidation of strategies for the implementation of prevention,
preparative stages, railway authorities of response and recovery.
