Evaluación de la peligrosidad en peatones por inundaciones urbanas.

Abstract

This research aimed to analyze information about the danger faced by pedestrians during urban flooding events. A thorough review was carried out, exploring the danger criteria proposed by various authors over time. These criteria were based on numerous experimental trials conducted in individuals with specific characteristics. During these trials, the sensation of stability of each subject was evaluated under various hydraulic conditions, including different draught levels and speeds. In Colombia, several authors have addressed this problem, focusing on computational models for the generation of risk maps. These maps help identify areas that present varying degrees of danger to pedestrians due to instability caused by flooding. It helps to better understand the location of industries that are most exposed to high, medium and low risks. It has also contributed significantly to closing the gap that existed only a few years ago. At that time, pedestrians were at risk of flooding in cities due to poor drainage systems and lack of relevant research. In addition, information was collected on various existing equations used to assess dangerousness. These equations were proposed considering empirical, semiempirical, mechanical and physical criteria.
