Enhancing adoption studies of LID-BMP’S for Storm Water Management Drainage (SWMD) national stadium in Jayapura, Indonesia

Abstract

The essential of this paper is implementing Low Impact Development (LID) type stormwater Best Management Practices (BMP’s) to reduce stormwater run-off in urban areas. The case study taken is the development area of Jayapura National Stadium. The drainage system at the main stadium is divided into subsurface and surface drainage. Meanwhile, the development area will enhance the study of adopting several LID-BMP’s practices to manage and optimize the design to control stormwater run-off in the stadium before it is discharged into the urban drainage system. The methodology in this study is divided into data collection and planning. The data collected include daily maximum rainfall data, stadium master plan, soil investigation, macro drainage system, drainage master plan, and topography around the stadium. Meanwhile, planning includes calculating rainfall design, soil structure analysis, hydraulic planning, pipe dimensions, and planning for water storage. The rainfall design used is a 5-year return period with Log Person III, the best design from the suitability test analysis, which is 134.39 mm/day. The study examined drainage design effectiveness to control stormwater run-off on the drainage design at the main stadium and surrounding stadiums using the LID-BMP’s framework and compared them. The LID-BMP’s adoption study was to optimize the drainage design to obtain maximum run-off control that can reduce up to 7-10% of stormwater run-off due to design and soil structure. The results provided recommendations to the authorities to modify the current design to achieve the benefits.
