Abstract

Malang City is the second city in East Java, facing an increased risk of flooding due to population growth, changes in land use, and reduced infiltration areas. Jalan Bareng Raya II is one of the affected locations, with flooding occurring on April 29, 2023 due to high rainfall intensity. This study aims to evaluate the condition of the existing drainage network in the area using quantitative descriptive methods, including data collection, analysis, and interpretation of results. The SWMM (Storm Water Management Model) application is used to simulate overflow channels. Primary data was obtained from direct observation, while secondary data came from the Malang City PUPR Service and BPS. The SWMM simulations show 11 channels overflowing, which can be reduced with a combination of infiltration wells and biopores.

Abstract

Climate change and rapid urbanization have intensified stormwater runoff in urban areas, including Malang City, while conventional drainage systems often lack the capacity to manage excess flow. This study aims to design and evaluate a rain garden model as a sustainable green infrastructure for reducing stormwater runoff in the GKB area of Universitas Negeri Malang, which frequently experiences inundation of up to 20 cm. The methodology involved rainfall analysis, probability distribution testing, and peak discharge estimation to determine the design parameters. The rain garden’s performance was assessed by comparing its storage capacity with the calculated runoff volume. Results indicate that for a two-year return period (0.134 m³/s), the proposed rain garden can fully accommodate runoff within its designed capacity. These findings demonstrate the potential of rain gardens as an effective nature-based solution to improve drainage efficiency and enhance urban flood resilience.
