Qualitative Investigation of the Application of Pervious Concrete as Pavement for Stormwater Runoff Management using Hydrologic Modelling System (HEC-HMS)

Abstract

Given its strategic location, numerous tropical cyclones enter the Philippine area of responsibility yearly. Through this occurrence, flooding has been one of the foremost problems particularly in the City of Manila. Given this, the researchers aim to assess the capacity of pervious concrete as it is applied as pavement through creating a pervious concrete sample and testing its capacity for compression and infiltration. Further reinforcing the analysis, the soil capacity for infiltration of the study area was also determined. Simulations depicting both the conventional and pervious concrete road were also created through the use of Hydrologic Modelling System. Through this, it was observed that there is a significant difference between both types of roads, predominantly with the behaviour of stormwater runoff with respect to the concrete pavements studied. Further analysing the hydrographs obtained from the simulations, the researchers had found that using pervious concrete for stormwater management would be certainly effective. To ensure its efficiency, several factors are to be considered such as the management of excess precipitation and the soil capacity of the area.
