Abstract

Kampung Rawa Bamban, Benda District, Tangerang City, is highly prone to flooding due to its flat topography, inadequate drainage systems, and uncontrolled water flow. High rainfall intensifies the issue, leading to prolonged inundation. Flooding results in significant material losses, disrupts daily activities, and degrades environmental quality. Therefore, an effective and sustainable solution is essential. This study aims to evaluate the effectiveness of detention ponds and pump systems as an integrated flood control strategy. The research employs topographic analysis, flood volume calculations, and hydrologic-hydraulic simulations to assess the performance of retention ponds and pumps. The detention pond functions as a temporary reservoir for stormwater runoff, while the pump discharge excess water into drainage channels once the pond reaches its capacity. The results show that the retention pond can store up to 1,208 m³ of stormwater. Based on land availability, the pond is designed with a surface area of 300 m² and a depth of 4 m, supported by a pump with a capacity of 300-liters-per-second. Model simulations indicate that the pond reaches near-maximum elevation at 05:36, prompting triggering pump activation at 05:37. After operating for approximately two hours, the pond is fully drained before 07:00. The combination of detention pond and pump is effective in reducing the flood extent and shortening the inundation duration. This study offers valuable insights for local governments in developing sustainable flood mitigation strategies.

Abstract

Tapin District, located in the Kuranji Watershed of South Kalimantan Province, frequently experiences flooding due to heavy rainfall. Flood event simulation can be utilized to generate hourly discharge data for flood early warning systems, addressing the absence of observed hourly discharge data from the Kuranji Automatic Water Level Recorder (AWLR). Moreover, limited watershed parameters and the unavailability of hourly rainfall data pose challenges in developing a hydrological model for the Kuranji Catchment. To overcome this issue, the hourly rainfall distribution pattern from 10 Global Precipitation Measurement Mission (GPM) Satellite grids were used to convert daily rainfall observations recorded at the Talaga Langsat, Lok Paikat, and Tapin Utara rainfall stations Hourly rainfall data from each GPM grid were matched with several synthetic hourly rainfall distribution patterns. The chosen distribution pattern was subsequently applied to simulate flood events using the HEC-HMS model. Two flood events, dated 4–7 March 2017 and 21–23 March 2018, were used for trial fitting to estimate catchment parameters. Simulated hourly discharges were compared with daily discharge data from the AWLR at Kuranji station, using Total Relative Volume Error (TRVE) and Root Mean Square Error (RMSE) as performance indicators. The simulation results demonstrate that daily-to-hourly rainfall conversion is applicable for estimating catchment parameters, with average TRVE and RMSE values of 1.955% and 7.025 m³/s, respectively. Furthermore, the trial fitting results indicate that the simulated discharge values align well with observed peak daily discharge data. Acquiring and incorporating hourly discharge data would enhance the accuracy of daily-to-hourly rainfall conversion by synchronizing the temporal resolution. Additionally, incorporating more flood events into trial fitting tests could produce more robust and representative outcomes.

Abstract

To increase food production in the Karang Agung Hilir Swampland requires effective water management by understanding the hydrodynamics of water quantity and quality; however, related research remains limited. This study aims to examine the characteristics of the Karang Agung Hilir Swampland in relation to tidal variability and water quality. The method used is correlation analysis with the variables of tidal hydrodynamics, land elevation, pH, electrical conductivity (EC), and salinity in the rainy and dry seasons. . Tidal influence is significant at the channel estuary but decreases toward the channel’s end. The land in the middle of the navigation channel is classified as hydro-topography A (<+2.00 m), B (+2.00 m to +2.30 m), and C (>+2.30 m). During the rainy season, the pH in the estuary and mid-channel is higher during spring tide than during neap tide, influenced by elevated EC values indicating saltwater intrusion during high tides. At the channel’s end, extremely acidic pH (<4.00) and EC values exceeding 2,000 µS/cm suggest the presence of an oxidized pyrite layer. In the dry season, pH levels in the channel are higher compared to the rainy season due to increased salt concentrations. Water management strategies are needed to enhance acid leaching, prevent pyrite oxidation, and limit saltwater intrusion. A one-way water management system is recommended to improve water circulation and supply, while maintaining water levels above the pyrite layer. This research is expected to provide recommendations for water management in swamplands with similar characteristics to this research location.

Abstract

River morphology is a condition that is constantly changing due to erosion and sedimentation in certain parts of the river. However, erosion and sedimentation that occur in undesirable parts of the river can cause significant losses to humans. One of the villages that has the potential to experience damage due to river erosion is Kalibuntu Village where there has been a shift in the river channel that has approached the residential area and increased the risk of landslides. Based on this, the construction of river groynes is planned to prevent further erosion. The use of river groynes must be in accordance with the characteristics of the river and its surroundings. Selecting appropriate designs and materials is very important to achieve effective results in preventing river erosion. To obtain the effect of groynes on changes in the magnitude and direction of flow velocity at the Kalibuntu bend, numerical modeling was carried out using MIKE 21 - Curvilinear software which is a hydrodynamic model. This method was chosen because the software can describe the morphological response of the river with relatively good accuracy. The numerical model was carried out with 2 series of models, the first simulating the existing conditions of the river, while the second simulated the normalization of the river with installed groynes as per the planned design. When compared to previous studies, this study only focuses on the effect of groynes on flow velocity as depicted from the results of 2D modeling and validated using field observation data based on several approaches, while a further novelty is that similar research has not yet been conducted at the selected study location. Based on modeling of 4 river segments, the installation of groynes showed a reduction in average flow velocity by 0.04 m/s at the starting point segment just before the river bend, by 0.111 m/s at the outer bend of the river, by 0.124 m/s at the outer bend segment of the river downstream, and an increase in average flow velocity by 0.157 m/s at the inner bend segment of the river.

Abstract

Uncontrolled land-use changes are a significant factor contributing to flooding, particularly in urban areas. A plot of land in the city of Bandung is planned to be developed into a place of worship. Due to the existing topographic conditions and future planning by the local government, a drainage channel will be constructed to convey runoff from the religious facility area and the adjacent western area to the Ranca Mekar drainage channel. This study examines the impact of runoff from these two areas on the flood water level in the Ranca Mekar drainage channel. Based on the analysis, the runoff from these areas increases the flood water level (MAB) in the Ranca Mekar channel by 20-25 cm for both 2-year and 10-year return periods. This increase in flood water level is exacerbated by blockages in segment J10, caused by channel narrowing and an upward slope. Additionally, sedimentation issues along the channel reduce its capacity. The study also evaluates three alternative solutions to address these problems. The results show that reducing the slope of the channel bed in segments J10-J12 can lower the flood water level by 11 cm, whereas widening the channel dimensions in segment J10 is less effective, reducing the water depth by only 5 cm. A combination of both alternatives results in a 12 cm reduction in flood water level in segment J10 for both the 2-year and 10-year return periods. Although some alternative solutions have been effective in reducing the flood water level, further studies are required to evaluate runoff management strategies in both the religious facility gereja area and the western region. Potential measures include the implementation of retention ponds, infiltration wells, and other mitigation approaches.

Abstract

Floods are an annual disaster that disrupt public services and cause financial losses. Climate change and urbanization are the main factors contributing to increased rainfall which challenges the capacity of conventional drainage systems. The aim of writing this article is to analyze the depth, inundation area and flow direction in the superblock development plan using HEC-RAS 2D hydraulic modeling. The method used is to combine hydrological analysis, namely calculating the rainfall distribution using the Gumbel method, with hydraulic modeling. Hydrological analysis is conducted to calculate the frequency analysis of return periods and peak flood discharge. The return period rainfall using the Gumbel method for a 5-year return period (R5) is 212.921 mm. The flood discharge was calculated using the Rational method with catchment area 12.96 ha, resulting in Q = 1.08 m³/s. In calculating the Rational peak discharge, a rainfall intensity value is needed. The rain intensity required in the Rational method calculation uses the IDF curve to obtain a value of 100.6 mm/hour. The rain intensity value is then processed using an equation and the planned peak discharge is produced. Then peak flood discharge data is inputted and simulated using two-dimensional hydraulic modeling with HEC-RAS version 6.3.1 to obtain flood water surface profiles, inundation area and flow direction. The height of the flood inundation resulting from twodimensional hydraulic modeling using HEC-RAS 6.3.1 is 42 cm, the inundation area is approximately inundation area is around 8.5 ha, and the flow direction during flooding is towards the east of the project site.

Abstract

The Cikakembang River, a tributary of the Citarum River in Majalaya District, has been polluted due to domestic and textile industrial activities. Although the Citarum Harum program, initiated in 2018, has been considered successful in improving water quality in the Citarum River, pollution in the Cikakembang River remains a serious issue. This study aims to analyze the impact of organic waste disposal on the water quality of the Cikakembang River using HEC-RAS. The modeling results obtained are then used as a basis for formulating pollution control strategies. This study focuses on four water quality parameters: BOD, DO, NH₃-N, and TP. In addition to field measurements of various technical data, this study also includes laboratory testing of twelve (12) water samples taken along the Cikakembang River. The data obtained are used to calibrate a mathematical model with statistical bias and relative error analysis as the objective function. Based on water quality testing results, it was found that the concentrations of BOD, DO, NH₃-N, and TP in the Cikakembang River do not meet Class II water quality standards as stipulated in Government Regulation No. 22 of 2021. Furthermore, HEC-RAS simulation results with various pollution control scenarios indicate that the existing conditions cannot fully address the issue. Therefore, stricter monitoring measures are needed for wastewater quality discharged into the water bodies, including enhancing the capacity of wastewater treatment plants and optimizing river rehabilitation programs to sustainably reduce pollution in the Cikakembang River.

Abstract

Pekalongan City, located on the northern coast of Central Java, is vulnerable to flooding due to high rainfall, low land elevation, land subsidence, sea level rise, and uncontrolled human activities. The Banger River, originally constructed as an artificial river to reduce flooding from the Loji River, has now become a source of flooding. This study aims to identify technical flood control solutions for the Banger River using spatial, hydrological, tidal, and hydraulic analyses supported by hydraulic flow modeling software. Twenty years of rainfall data, spatial data, river geometry, and tidal information were used to simulate existing and projected long-term conditions. The design flood discharge with a 20-year return period was calculated at 281,9 cubic meters per second, resulting in an average inundation of 0,27 meters, which may rise to 0,85 meters within the next ten years due to land and sea level changes. Three alternatives were evaluated: normalization with earth embankment, a combination of normalization and parapet, and parapet-only implementation. Results indicate that using parapets, or combining them with river normalization and embankments, offers the most technically effective flood control solution in both short and long terms. Overall, the study emphasizes the need for adaptive flood management strategies in coastal urban areas. It is recommended that local governments integrate structural measures with nonstructural policies, such as land use regulation and public awareness, to ensure sustainable flood risk reduction.
