Bioretention Basin, Rain Garden, and Swales Track Concepts through Vegetated-WSUD: Sustainable Rural Stormwater Management in Klaten Regency

Abstract

Abstract The rural area is one area with a vital function as a food producer towards food security which urgently needs sustainable stormwater management. However, the challenge of sustainable stormwater management is climate change. WSUD is one of the most influential sustainable stormwater because WSUD can control the hydrological cycle and water quality through local facilities. Vegetated WSUD is a practical application of WSUD in regulating stormwater management because it is easy to apply. Vegetated-WSUD consists of a bioretention basin, rain garden, and swales track. Klaten Regency is an area in the province of Central Java that is ranked 9th in the highest drought level in Indonesia, and eleven sub-districts are prone to flooding. On the other hand, Klaten Regency is the largest producer of rice suppliers in Central Java which requires sustainable stormwater management. The research aims to formulate a design simulation model through bioretention, rain garden, and swales track through WSUD to achieve sustainable rural stormwater management. The research method used is quantitative with map overlay and design mapping. The research outputs determine the location feasibility and design model application of vegetated-WSUD in the Klaten Regency. The two-dimensional and three-dimensional design model consists of space requirements, placement, and vegetation types from each bioretention basin, rain garden, and swales track.
