The development of green infrastructure through optimization of water resources carrying capacity in Yogyakarta urban area

Abstract

The development of Yogyakarta Urban Area has spread to its surroundings. As a result, water resources carrying capacity and environmental problems are worsening. Rainwater harvesting (RWH) development as part of green infrastructure is one of the important methods to increase water resources carrying capacity. Relating to the problem, this research was conducted in Yogyakarta Urban Area. The study was a combination of field research and studio analysis. The field study measured the settlement’s physical parameters and surveyed the community’s socio-economic and cultural aspects. According to the physical and economic analysis based on CBR, the recommended models of water resource conservation infrastructure were absorption well/1.10; conservation pond/4.53; open space/7.47; and green space/3.59. Meanwhile, rainwater reservoir was not suggested because the CBR value was only 0.18.
