The increase in rainfall intensity caused by climate change, combined with high levels of urban soil sealing and the limited capacity drainage systems, is significantly increasing flooding risk. Integrated stormwater management a key factor dealing consequences change mitigating flood risk based on nature-based solutions. An experimental site was designed to assess hydrological response vegetated swales depending different catchment surfaces, evaluate impact spatial variability hydraulic conductivity (K). A model developed EPA SWMM calibrated measured data two active surfaces (N6—50 m2 N11—100 m2). validation assessed NSE scores higher than 0.7. simulations considered various factors, such as water level swales, actual rainfall, evapotranspiration, swale geometry, area (Sa), conductivities natural silty soil, assess, for heaviest event, best morphological characteristics. study examined K (8) Sa (6) storage capacity, 250 mm depth. showed that overflow limit exceeded N10 (90 m2) when ≤ 2 × 10−6 m/s, N11 (100 4 m/s.

A GIS-based approach to determine the priority area for rainwater harvest in Kupang

IOP Conference Series Earth and Environmental Science, Год журнала: 2024, Номер 1311(1), С. 012032 - 012032

Опубликована: Март 1, 2024

Abstract Kupang, a pivotal economic and administrative hub in Nusa Tenggara Timur, Indonesia, faces recurring droughts resulting crop failures, food insecurity, health problems. Addressing this water crisis entails rainwater harvesting as potential solution. This study establishes comprehensive framework for prioritizing areas Kupang. Using the weighted overlay method open-source GIS software, our approach involves three stages: identifying drought flood priority zones, defining suitability indicators, quantifying of systems. By leveraging climatological, geological, hydrological information, we determine management. Our analysis integrates climatological land use cover mapping, runoff assessment, index. Quantification system requirements hinges on rooftop area population data. The entire wards Kupang are classified high priorities mitigation. Therefore, is viable strategy all wards. most prioritized in-demand wards, Oesapa, Sikumana, Lasiana, Liliba, have to install minimum 12,000 systems, each with 1500-liter volume barrel.
