Abstract

This study investigates the flood vulnerability of the Cipager River Basin through integrated hydrological and hydraulic analysis. Maximum daily rainfall data from UPTD Mandirancan, UPTD Cilimus, and Cipager Weir were analyzed using four statistical models—Gumbel, Log-Normal, Normal, and Log-Pearson Type III—to estimate design rainfall for return periods of 2 to 100 years. The Log-Normal model produced the most conservative rainfall values, while the Log-Pearson Type III showed anomalous behavior at higher return periods, raising concerns regarding its reliability for modeling extreme hydrological events. Using Manning’s equation, design discharges were derived and compared against the hydraulic capacities of 12 river segments. Results indicate that many segments, particularly Megu Gede, Astana, and Jatimerta, have discharge capacities below 1 m³/s, far below the design discharges associated with longer return periods. This mismatch was further validated during the January 2025 flood, which caused severe inundation in subdistricts such as Weru, Tengahtani, and Gunung Jati. Compounding these risks are physical constraints including channel narrowing, sediment accumulation, and encroachment into riparian zones—conditions exacerbated by weak enforcement of spatial planning regulations. The study recommends structural measures such as river normalization, sediment control, and retention basins, alongside policy enforcement and real-time hydrological monitoring. By aligning statistical discharge modeling with actual river capacity, this research offers a strategic framework for flood risk reduction and supports evidence-based decision-making for climate-resilient watershed management in the Cipager River Basin.

Abstract

Floods are hydrometeorological disasters that significantly affect communities, infrastructure, and the environment. This study aims to assess the capacity of the Cisanggarung River to accommodate flood discharge flow using HEC-RAS software. The analysis was based on rainfall data from three observation stations: Losari Station, Cangkuang Station, and Gebang Station. The research utilized frequency analysis, probability distribution tests, and hydrological and hydraulic simulations to evaluate the river's ability to handle floodwaters. The findings indicated that the current cross-section of the Cisanggarung River is insufficient to accommodate the planned flood discharge of 904.8 m³/sec, suggesting the need for river normalization efforts. This study provides critical insights for flood mitigation strategies, including infrastructure improvements and watershed management optimization. By implementing effective mitigation measures, the risk and impact of flooding in the region can be significantly reduced, contributing to improved flood resilience and urban planning.

Abstract

Irrigation network maintenance plays a strategic role in ensuring efficient and sustainable water distribution to support agricultural productivity. This research aims to analyze the condition of the irrigation network and calculate the Actual Operation and Maintenance Needs (AKNOP) at the Cirongkob Weir in Kuningan Regency, West Java. The research method uses a quantitative and qualitative approach through field observations, water discharge measurements, evaluation of irrigation channels and structures, and calculation of maintenance costs based on the technical guidelines of the Ministry of Public Works and Housing (PUPR). The analysis results show that the irrigation channels are generally functional, although light to moderate damage was found that affects water distribution efficiency. AKNOP calculations indicate that most of the budget is allocated to rehabilitation and contractual maintenance activities. Efforts to improve irrigation efficiency should focus on optimizing routine maintenance, strengthening farmers’ institutions (P3A), and implementing water discharge monitoring. Through these strategies, the sustainability of the irrigation system and food security in the Cirongkob area can be maintained. The implications of this research provide empirical foundations for evidence-based irrigation management policies, contribute to the development of standardized AKNOP calculation methodologies for similar irrigation systems across Indonesia, and offer practical guidelines for optimizing budget allocation in irrigation infrastructure maintenance.

Abstract

The urban area of Cirebon City, Indonesia, with its tropical climate, in the Sunyaragi sub-district, is increasingly affected by surface runoff and flooding due to limited drainage capacity and extensive impervious surfaces. This study evaluates the effectiveness of a modular infiltration box system in reducing urban stormwater runoff. Hydrological data from Harjamukti, Kamun, and Kertajati stations from 2014 to 2023 were analyzed using a Log Pearson Type III distribution to determine rainfall intensity for return periods of 2, 5, and 10 years. Field Experiment and Laboratory Analysis Methods: Soil infiltration characteristics were tested using a double ring infiltrometer and modeled with the Horton infiltration equation. Infiltration boxes measuring 1.00×0.50×0.45m were installed on the road median in two configurations, single layer (22 units) and double layer (44 units). The results showed that the single-layer system reduced runoff by 43.06% for a 5-year return period (15-minute duration), while the double-layer system achieved a reduction of up to 86.60% for a 2-year return period (20-minute duration). Further improvements were observed when combined with infiltration wells, achieving runoff reductions of over 95%. These findings demonstrate that modular infiltration boxes are an effective and scalable alternative solution for decentralized urban stormwater management, contributing to flood mitigation and sustainable drainage planning.

Abstract

The development of a city results in increased urbanization. This development leads to changes in land use in urban areas, creating large areas covered by buildings and roads, which reduces infiltration and increases surface runoff. With high rainfall of 147.238 mm per month, Sunyaragi Village often experiences flooding during the rainy season, especially on St. Taman Pemuda. This study aims to determine the number of infiltration wells needed to reduce the risk of flooding in Sunyaragi Urban Village, Cirebon City. The research employs descriptive methods using Arc-GIS remote sensing and quantitative methods, including hydrological analysis to measure rainfall intensity, hydraulics analysis to assess drainage channel capacity, and infiltration well analysis to determine the required number of infiltration wells. Based on the analysis results, the maximum runoff discharge value in the 5-year return period on St. Taman Pemuda is 0.00562 m³/sec, indicating that eight infiltration wells are needed. These wells are planned to be cylindrical, with a diameter of 1 m and a depth of 3 m, achieving an efficiency value of 85.04% in reducing runoff discharge.

Abstract

Problems that often arise in the city of Cirebon are flooding caused by rain, land changes not supported by adequate infrastructure, narrowing of drainage channels and sedimentation of channels. This is the location where flooding often occurs in the Pemuda Street area and its surroundings. Therefore, it is necessary to carry out research on surface flow analysis as an effort to handle floods with the aim of inundation management strategies to reduce excessive rainwater runoff in drainage areas and channels. The research methods used were problem identification, literature study, data collection, analysis and design planning. The results can show that inundation is handled in two ways, first by changing the dimensions of the channel at the initial height H to 0.45m, it still experiences inundation, this is due to the difference in elevation which causes inundation in the channel. There was a change in the flood inundation area to 23,127 ha from the original 58,958 ha, meaning that the flood free area increased from 9,388 ha to 35,831 ha. The second way is by making 378 infiltration wells spread across 34 channels that experience flooding. With these infiltration wells, the flooding can be reduced to a minimum from an area of ​​23,127 ha to 0.040 ha. The success rate for flood management efforts reached 99.908%, with failure being 0.092%. Of the area of ​​68,346 ha, the flood-free area reached 68,306 ha and the remaining inundated area was 0.040 ha..
