Abstract Southeast Asia is vulnerable to climate change with over half of its population already being impacted by drought, flooding, and rise in sea levels recently. This work reviews the current water resource challenges Indonesia, prone rising impacts change. A baseline assessment Indonesia's drinking resources related original sources presented. In response a growing concern chronic that undermine supply nationwide, this study analyses safety supervision. To accomplish this, literature survey (100 studies published during 2000–2023 period) was performed identify regional groundwater sustainability security issues. Among main findings study, only 10% rainfall infiltrates groundwater, while 70% rivers are heavily polluted domestic waste. During period, availability decreased 1,200 m3/year 2020, 35% economically feasible for reuse. The deficit Indonesia estimated be 5.5 hm3/year roughly 67% population's demand satisfied 2021. Although might fulfilled private vendors, supply/demand forecasts 2030 suggest gap could not closed increasing supply.

A sponge campus is a implemented with Low Impact Development (LID) facilities aimed to improve its urban resilience and stability against the effects of climate change by enhancing storm water management. In this study, secondary school was designed transformed into installing LID facilities, we found it high runoff control effect energy conservation potential. Using Storm Water Management Model (SWMM), study assessed performance under different rainfall intensities recurrence periods 1, 5, 10, 20 years. The SWMM modelling revealed that peak flow reduced 59.1%, 54.5%, 47.9% 46.8%, respectively, while total inflow 33.9%, 28.0%, 25.4% 24.6%, respectively. achieved suspended solids (TSS) removal 75%. Specifically, accounted for 9.2% plot area contributed 15.1% storage capacity neighbouring region (recurrence period 1a). Furthermore, implementation on could help conserve 17,524 kW·h electricity annually. Overall, provides useful insights guidance construction campuses.

The population increases, leading to extensive urbanization and the consequent rise in impervious surfaces. This trend has exacerbated stormwater runoff issues, necessitating sustainable management strategies. Low Impact Development (LID) techniques, such as bioretention, have emerged promising solutions mitigate adverse effects of increased surfaces on management. Through drainage simulation using EPA SWMM 5.2 software, this study assessed effectiveness bioretention mitigating within Pesona Regency Housing Jember Regency. In approach, hydrological techniques use rainfall for a 2-year return period based typology area. scenarios used coverage 5%, 10%, 20% subcatchment area Scenario 1, 2, 3. revealed reductions peak discharge across various scenarios, with average reduction rates 80%, 88%, 92% Scenarios 3, respectively. However, varied different junctions due factors location, junction coverage, soil properties, local patterns. While larger areas generally resulted greater reduction, underscores importance considering location cost-effectiveness design. Overall, research provides valuable insights into efficacy strategy rapidly urbanizing areas, offering guidance property developers planning flood-resistant housing LID bioretention.

This study explores the improvement of performance pervious concrete (PC) for enhancing urban runoff quality by incorporating fine-grained iron slag in varying proportions, from 0% to 15% coarse aggregate weight. The research addresses pressing challenges stormwater management areas, where impervious surfaces contribute significantly increased and water pollution. To tackle these issues, aims optimize PC composition. Mechanical physical properties, including compressive strength, hydraulic conductivity, void content, were assessed. top-performing mixes further evaluated their ability improve using a rainfall simulator slabs measuring 650×450×100 mm. Initial findings showed positive relationship between higher content with gains up 13%. However, this came reduced porosity permeability as increased. Notably, sample demonstrated high pollutant removal efficiencies: 42.7% chemical oxygen demand (COD), 43.68% total suspended solids (TSS), 33.95% turbidity, due dual effects pore filling contaminant adsorption slag. No significant changes observed NaCl electrical conductivity (EC) levels. highlights potential optimizing enhance its role management, presenting promising approach improving settings.

Pluvial flooding, driven by increasingly impervious surfaces and intense storm events, presents a growing challenge for urban areas worldwide. In Baltimore City, MD, USA, climate change, rapid urbanization, aging stormwater infrastructure are exacerbating flooding impacts, resulting in significant socio-economic consequences. This study evaluated the effectiveness of soil profile rehabilitation scenario using 2D hydrodynamic modeling approach Tiffany Run watershed, City. utilized different extreme high-resolution (1 m) LiDAR Digital Terrain Model (DTM), building footprints, hydrological data. These datasets were integrated into fully coupled model, City Catchment Analysis Tool (CityCAT), to simulate flood dynamics. The pre-soil simulation revealed maximum water depth 3.00 m most areas, with hydrologic groups C D, especially downstream area. post-soil was targeted at vacant lots public parcels, accounting 33.20% total area watershed. resulted reduced 2.50 m. Additionally, baseline runoff coefficient 0.49 decreased 0.47 following rehabilitation, model consistently recorded peak reduction rate 4.10 across varying rainfall intensities. validation contingency matrix demonstrated true-positive rates 0.75, 0.50, 0.64, 0 selected confirming model’s capability capturing real-world occurrences.

Abstract In recent years, rain barrels (RBs) have emerged as effective stormwater management tools for mitigating urban flooding. Our previous study in Saitama City revealed that traditional RBs performed poorly the densely populated residential areas compared to other low-impact development solutions. This investigated effectiveness of smart RB, comprising water pumps. These SRBs can be controlled online using switches rely on local weather forecasts, ensure are emptied before rainfall. We aimed assess how reduce pluvial flooding during continuous rainfall PySWMM model. varied drainage values simulations control activation switches, enabling us evaluate flood reduction. The results showed reduced total runoff volume by 2–10% RBs. Moreover, although reduction effect was found independent their size, increased proportionally with capacity.
