The Study of Biopore Infiltration Holes (BIH) Implementation to Reduce Waterlogging in President University Campus Area

Abstract

The continuous infrastructure development results in the lack of green open space as water catchment areas into the ground. The reduced water infiltration zona will cause runoff. The soil on President University's campus is fine-grained, with high plasticity due to clay mineral particles. One factor that affects rainwater utilization is the soil type. Clay types have slower permeability, resulting in reduced rainwater infiltration areas. One of the technologies to reduce water runoff is the Biopore Infiltration Hole (BIH). To find out how much water can infiltrate into the soil to reduce waterlogging and to plan the total amount of Biopore Infiltration Hole (BIH) that can be applied at President University. This study uses quantitative analysis methods to identify the ideal Biopore Infiltration Hole (BIH) requirement on President University's campus and determine the BIH. The findings of this study indicate that the total planned implementation of BIH that can be used on the campus of President University is 1711.8 pcs in an open space zona of 13,600 m2 and, based on the annual infiltration calculation, is 0.97 m3/min that significant enough to reduce waterlogging in the President University Campus Area.
