Abstract

This study aims to apply Water Resources Urban Design (WSUD) technology to improve water quantity and quality in the Brantas River Watershed (DAS), especially in Oro-Oro Dowo Village, Malang City. This village was chosen because several drainage channels have decreased efficiency in accommodating water runoff during the rainy season. The application of WSUD technology is expected to reduce the high surface runoff due to the decrease in water absorption areas, so this can be an alternative to conserving the availability of water resources in terms of quantity and quality. The modeling scenarios are arranged into two types. In the first scenario, the model is made without the application of WSUD, while in the second scenario, WSUD technologies are applied. There are permeable pavement, bioretention, constructed wetlands, and green roofs. The methodology used for the application of the WSUD concept is through the SWMM (Storm Water Management Model) program. The application of WSUD technology in the case study in Oro-Oro Dowo Village is planned along the sidewalks on Jalan Rinjani, Jalan Jakarta/Jalan Simpang Ijen, Jalan Besar Ijen, and Jalan Panggung, as well as green open spaces/city forests located in the administrative area of the village. The results of this study are in the form of a comparison of the total surface water runoff before and after the implementation of WSUD for each technology. As a result, green roof technology has the potential to reduce surface runoff higher than other technologies. However, the obstacles in the application of green roofs are the cost and roof leaks. Thus, the application of a combination of permeable pavement, bioretention, and constructed wetlands can be another option. The results of the application of the WSUD combination reached 96.88%.

Abstract

Indonesia is committed to supporting national strategic programs, one of which is food self-sufficiency. Therefore, to achieve optimal irrigation during the dry season, planning for reservoir construction is necessary. One crucial analytical activity in reservoir planning is hydrological analysis. This analysis determines the structural design requirements and the extent of the reservoir's irrigation benefits, provided sufficient data is available. Unfortunately, rainfall data from observation posts is sometimes incomplete, necessitating the use of satellite rainfall data. This study aims to analyze the potential use of Global Precipitation Measurement (GPM) satellite rainfall data as a primary source of hydrological analysis for reservoir planning, particularly in determining the design flood discharge for the return period. The limited availability of observed rainfall data in Indonesia is a major obstacle in the water structure planning process, particularly in rural areas and upstream river basins (DAS).
