Abstract

The field practicum was conducted at the Wack Wack Golf and Country Club (WWGCC). During the practicum, some portions of the East Course of WWGCC were under renovation and some portions were newly renovated. Hence, there is a need to evaluate these reformations. The study focused on the drainage evaluation of the East Course. Holes 5 and 6 were used to represent the entire East Course since these two areas have the most problematic drainage system based on WWGCC's observation. The area was surveyed using an engineer's transit. Rod readings were taken at spots that define shape of the area such as Hole boundaries, waterway boundaries, and spots that causes irregularities in the grade of the course. A topographic map of each Hole was created using the AutoCAD 2010 software. Catchment areas that will drain to each pipe section determined using the software as well. Also, the slope of the drainage pipes for each Hole was obtained. The drainage system utilizes pipes as means of conveying the drainage water into the waterway outlet. Considering the hydraulic radius, roughness coefficient, and slope of the pipes, the Manning's equation was used to determine the flow velocity in each pipe section. Given the cross-sectional area of the pipes, the computed flow velocity in each section was considered and the continuity equation was used to determine the design flow rate. Then for each pipe section, the rational equation was used to determine the design rainfall intensity. The runoff coefficient of turf glass, design flow rate of each section and their respective catchment areas were considered. Using the rainfall data obtained from the weather station of WWGCC, hydrologic frequency analysis was done using different rainfall duration and the probability of occurrence and the recurrence interval were determined. It was concluded that the drainage system of the East Course of WWGCC can handle 38.83mm of rainfall per hour. Its corresponding probability of occurrence and return period id 44% and 2.27 years respectively. It means that there is 44% probability that the design rainfall intensity will occur. Moreover, based on the rainfall data used, the design rainfall event occurs once in every two years and three months. This obtained value was found to conform to the standard recurrence interval for a minor drainage system.
