Abstract/Executive Summary

Flooding is a common and persistent challenge in the Philippines. During heavy rainfall, the gymnasium of a private educational institution is frequently flooded, implying that the existing drainage system is inadequate in handling stormwater. Therefore, this study optimized a proposed drainage system using a detention tank, pervious concrete pavements, and diversion channels to enhance flood control within the area. The study aimed to find how flow rates are affected by the composition and arrangement of the drainage system, the efficiency of the drainage system under certain rainfall intensities, the effect of degradation on the drainage system's performance, the theoretical adequacy of the drainage system in enhancing flood control, and what proposal can be formed based on the results. The study optimized the arrangement of the drainage system by simulating three configurations under different rainfall intensities and levels of degradation using the Stormwater Management Model. Efficiency was measured based on set ranges for different parameters, particularly velocity, flow ratios, and depth ratios. Based on the results, the study found similar efficiencies among the three configurations, primarily due to minimal differences in composition and arrangement. Therefore, the researchers selected configuration 1 for the proposed drainage system design due to practicality in terms of the number of inlets. The researchers deduced that the efficiency of a drainage system is mainly dependent on the different properties of the components, such as the surface permeability, pipe slopes, pipe diameter, and pipe material, recommending that future researchers explore different orientations of different drainage system components.
