Abstract

Effective reservoir management can be supported by applying rainfall-runoff hydrological models. However, one of the main challenges of such models lies in the availability of reliable rainfall data. Satellite-based rainfall data offer a viable alternative to address this issue. This study aims to evaluate the reliability of satellite-based rainfall data for hydrological applications, specifically for simulating reservoir inflow using the HBV-96 model in the Selorejo Reservoir. The rainfall data used in this study include satellite-based datasets from TRMM, GPM, and RCM, tested in both raw and corrected forms. The HBV-96 model parameters were calibrated using observed rainfall data from 1998 to 2008, achieving a correlation coefficient and Nash-Sutcliffe Efficiency (NSE) of 0.86 and 0.72, respectively, for simulated streamflow. The model's performance was subsequently verified using observed rainfall data from 2009 to 2016, yielding consistent results with a correlation coefficient and NSE of 0.832 and 0.71, respectively. These calibrated parameters were then applied to the satellite rainfall datasets. The findings reveal that, in general, corrected TRMM satellite rainfall data using regression equations were not suitable for hydrological modelling. However, TRMM data corrected using duration curves significantly reduced deviations by up to 50% compared to raw data and provided better-simulated streamflow results, aligning more closely with observed streamflow. Conversely, RCM rainfall data, whether raw or corrected, performed poorly in the HBV model, with negative NSE values. Meanwhile, the bias-corrected GPM satellite rainfall data demonstrated the best performance in the HBV model, with a maximum deviation of only 5.81%.

Abstract

The Frequency Ratio (FR) method combined with Geographic Information Systems (GIS) was applied to map groundwater potential in the Bedadung Watershed, Jember Regency, Indonesia. The study was conducted from September 2024 to January 2025 by analyzing 136 spring locations across an area of 9,590.83 km². The main objectives were to identify factors influencing groundwater potential, validate the predictive model using the Area Under the Curve (AUC) method, and produce a detailed groundwater potential map. A total of 14 environmental parameters were considered, including Elevation, slope, and vegetation density. Model validation produced an AUC value of 73.8%, indicating a good level of predictive accuracy. The highest groundwater potential was observed in the sub-districts of Sukorambi, Arjasa, Sukowono, and Kalisat, where more than 50% of the area falls into the very high potential category. In contrast, Panti Sub-district demonstrated limited groundwater availability, with 59% of its area classified as low to very low potential. The resulting groundwater potential map was classified into five categories: very low, low, moderate, high, and very high. These findings provide a scientific basis for sustainable water resource management, emphasizing conservation strategies in high-potential areas and infrastructure development in low-potential zones. The effectiveness of the FR method in spatial analysis is reaffirmed, offering valuable insights for groundwater management in the Bedadung Watershed.

Abstract

The water supply at the IPB Education and Research Garden Jonggolis generally sourced from rainfall. This can lead to water shortage during certain periods, so building a water storage structure such as a small reservoir (embung) is necessary. The embung can provide a more stable water supply by storing rainwater and river inflow. This research aims to design an embung at the IPB Education and Research Garden Jonggol, and to analyze the water balance of the planned embung. This study presents the application of SWAT-based dependable discharge analysis for small-scale industrial reservoirs in tropical regions. The findings support sustainable water management and enhance enhance agro-industrial resilience, particularly in regions dependent on rainfall. The planned embung is designed for the palm oil processing plant with a total water requirement of 8,786 m3 in the dry season. Dependable discharge analysis is conducted using Soil Water Assessment Tool (SWAT), while flood discharge analysis uses the rational method. Embung capacity design is based on water availability, water requirement, sediment volume, and total evaporation. The planned embung will be located at coordinates 107° 2' 10.53" E and 6° 28' 17.60" S. It features a normal water surface area of 7,737.19 m², a normal water depth of 3 m, and a total storage volume of 9,947.76 m³. The design includes essential components such as an overflow channel, an outlet channel, and an embankment. The water balance indicates that the embung will begin filling in February and remain full from March to May. Subsequently, the water balance is expected to repeat its cycle consistently, ensuring that the embung can meet the water demand at the location.

Abstract

Bogor City, with a population of approximately 1,064,000 in 2022 and an annual growth rate of 2.01%, faces increasing pressure to meet housing demands. To accommodate this need, one modern residential development in the area has undergone extensive expansion. A previous assessment indicated that the development of a 10.75-hectare residential area in this neighborhood could increase peak discharge by approximately 24.74% for the 2-year return period and 16.67% for the 5-year return period.Based on these findings, this study aims to evaluate the effectiveness of Low Impact Development (LID) measures, specifically the use of rain barrels, in mitigating the hydrological impacts of land-use changes. Simulations were conducted using the Storm Water Management Model (SWMM) to: (1) analyze changes in peak discharge and runoff volume before and after development; (2) design the residential drainage system while testing different rain barrel capacities; and (3) evaluate the effectiveness of rain barrels in reducing peak discharge and runoff.Simulation results indicate that the installation of two rain barrels per household, each with a diameter of 1.41 m and a height of 1.19 m, can reduce peak discharge by 19.66%, approaching pre-development conditions. However, total runoff volume remains higher than baseline levels, suggesting that additional LID strategies are necessary for more comprehensive flood mitigation. These findings underscore the potential of rain barrels as an effective tool for urban runoff management and provide practical guidance for optimizing their implementation in similar residential developments.

Abstract

Flood disasters, with their increasingly common occurrence and shorter peak discharge times, have led to more significant runoff and elevated flood risks. Taliwang City, the economic center of West Sumbawa Regency, is particularly vulnerable to flooding, despite the presence of the natural reservoir, Lake Lebo Taliwang. The construction of the parallel Bintang Bano and Tiu Suntuk dam is expected to significantly reduce flood impacts. This study aims to analyze peak flood discharge and conduct flood inundation modeling to assess how reservoir routing from dam inflow and Lake Lebo Taliwang affects flood conditions in the Rea watershed. Flood discharge analysis was performed by converting rainfall data into flow hydrographs using HEC-HMS software, while flood inundation modeling was carried out using HEC-RAS (2D) software. The input for the HEC-RAS model included flood inflow from the Rea sub-watershed, differentiated by the 50-year return period (Q50) discharge, both before and after considering the effects of reservoir routing. The results showed a significant reduction in peak discharge for the Q50 return period post-dam construction, decreasing from 3,198.42 m³/s to 1,575.72 m³/s—a reduction of 50.73%. Additionally, the area affected by flooding shrank by a substantial 33.96%, from 4,016 hectares to 2,652 hectares, demonstrating the practical benefits of the dam construction. The depth of flooding along the riverbanks decreased from 1.14 meters to 0.63 meters, while it was reduced in Taliwang City from 0.42 meters to 0.08 meters.

Abstract

Lake Sentarum has a unique role as flood control in the lower reaches of the Kapuas River Basin. Changes in land use and high rainfall can cause an increase in the rate of erosion and sedimentation that occurs in the Sentarum Sub-river basin, which potentially reduces the storage capacity of Lake Sentarum. The objective of this study is to determine the sedimentation rate and analyze the impact of sedimentation on the storage capacity of Lake Sentarum.The erosion rate analysis using the Universal Soil Loss Equation (USLE) method shows that in the 2015 to 2020 period, the most significant erosion rate occurred in 2016,which 2016 was the year with the highest rainfall. The erosion rate that occurred in 2016 in the Sentarum Sub-river basin and Lake Sentarum catchment area was 293,622.79 Ton/Ha/year and 160,413.01 Ton/Ha/year, respectively. The types of land cover that have the most impact on erosion rates are dryland agriculture mixed with shrubs, plantations, shrubs, and open land. The sedimentation rate was calculated using the Sediment Delivery Ratio (SDR) method, where the most significant sedimentation rate occurred in 2016 with the sedimentation rate of the Sentarum Sub-river basin was 201.842,37 Ton/Year which resulted 86.702,05 m3 of sediment volume and the Lake Sentarum catchment sedimentation rate was 117.591,64 Ton/Year which resulted in 50.511,87 m3 of sediment volume. With an average sediment volume in the Lake Sentarum catchment from 2015 to 2020 of 42,668.05 m3, Lake Sentarum will lose its capacity by 0.001% each year.

Abstract

Trenggalek Regency in East Java Province is considered vulner between these two drought typesable to drought due to uneven rainfall distribution and predominantly hilly topography. This study aims to assess the levels of meteorological and hydrological drought hazards and to examine the relationship between these two types of drought within the region. Meteorological drought was analyzed using the three-month Standardized Precipitation Index SPI-3,  derived from rainfall records obtained from 18 rainfall stations. Hydrological drought was evaluated using the three-month Standardized Runoff Index SRI-3, based on discharge data from several streamflow gauging stations within the Brantas sub-watersheds. The spatial distribution of drought hazards was mapped using the Inverse Distance Weighted (IDW) interpolation method within a spatial analysis framework. The results indicate that the southern coastal area of Trenggalek Regency experiences high to very high meteorological drought hazard, whereas the mountainous regions exhibit relatively lower drought hazard due to higher rainfall intensity. Hydrological drought analysis reveals that drought hazard levels vary from very low to moderate across several gauging stations. The discrepancy between meteorological and hydrological drought conditions is influenced by the presence of baseflow derived from groundwater storage, which helps sustain river discharge during dry periods. Correlation analysis between SPI-3 and SRI-3 demonstrates a positive relationship, with correlation coefficients ranging from 0.41 to 0.79, indicating that meteorological drought generally precedes hydrological drought with a detectable lag time. These findings provide important insights for improving drought mitigation strategies and supporting sustainable water resources management in Trenggalek Regency

Abstract

On 7 March 2019 and 31 December 2021, extreme rainfall events occurred in the Wae Mese Watershed, West Manggarai Regency, resulting in the inundation of several villages and agricultural fields. Currently, detailed records regarding the area and depth of these flood events are unavailable, hindering the formulation of comprehensive disaster mitigation plans. This study aims to reconstruct the flood inundation area and depth in the Wae Mese Watershed, while simultaneously evaluating the accuracy of various open-access Digital Elevation Models (DEM). The flood inundation simulation was performed using a two-dimensional (2D) HEC-RAS hydraulic model, driven by flood discharge values derived from a rainfall-runoff model using recorded rainfall data during the events. The flood model simulation results were calibrated against the inundation depth from the 2019 flood event in Golo Bilas, Macang Tanggar, and Gorontalo Villages. The inundation modeling incorporated four open-access DEMs: SRTM DEM, Merit DEM, NASA DEM, and DEMNAS. Simulation results indicated that DEMNAS yielded an inundation depth of 1.03–2.03 m and an inundation area closest to the actual flood event on 7 March 2019. The statistical indicators, such as an RMSE of 0.38, a BIAS of 0.15, a correlation coefficient of 0.92, and a RVE of 10.6%, show that the results are close to the actual flood.  The superior performance of DEMNAS is attributed to its higher spatial resolution compared to the other DEMs, providing a more precise representation of surface topography for modeling inundation areas and river channels. Consequently, DEMNAS is recommended as a reliable reference for developing flood hazard maps and planning flood mitigation strategies in the Wae Mese Watershed.

Abstract

Dams are vital infrastructure that supports irrigation, raw water supply, flood control, hydroelectric power, and tourism. Reservoirs of the dam store the water during the rainy season and release it in the dry season to reduce the flood risk. Continuous monitoring is essential to ensure their optimal function and safe operation. However, in many developing regions, the availability and quality of discharge data remain inadequate due to poor data governance, limited resources, and insufficient digital infrastructure. These challenges highlight the need for new approaches capable of improving discharge prediction under limited data conditions. To address this issue, Machine Learning (ML) has gained popularity in hydrological research. Long Short-Term Memory (LSTM) is one of the ML methods that has proven effective for analyzing historical data patterns for prediction. This study uses an LSTM-based hydrograph model in the Pandanduri Reservoir Watershed, Indonesia. Compared to conventional statistical or conceptual models, LSTM offers the advantage of capturing nonlinear dynamics in long time-series datasets. The model utilized open data, including satellite rainfall data, meteorological data, and streamflow data records, to capture the complex relationship between rainfall and streamflow.  The generated model was validated with the recorded streamflow data. The model evaluation produces an NSE of 0.44 and an RMSE of 0.74. These values indicate that the model is capable of reproducing key rainfall–runoff dynamics under data-limited conditions. Further research is essential to improve the ability of LSTM to capture extreme events and improve its generalization across hydrological conditions.

Abstract

Phosphate pollution from domestic detergent wastewater poses a significant challenge to urban water quality, particularly in small drainage channels where detergent-derived sources and dispersion patterns have not been thoroughly investigated. This study focuses on the Cibarani Channel in Bandung, Indonesia, where phosphate primarily originates from household detergent discharge. The objective was to model the spatial–temporal dispersion of total phosphate (TP) and evaluate two control strategies: substitution with low-phosphate detergents and partial technical reduction of TP concentration. A steady-flow hydrodynamic and water quality model was developed using HEC-RAS by incorporating field data on flow discharge, TP, DO, BOD, and NH₃–N, as well as community survey results. Model performance was evaluated using R², RMSE, and Nash–Sutcliffe Efficiency (NSE). Simulations during wet and dry seasons showed that TP concentrations consistently exceeded the Class II water quality standard (0.2 mg/L), reaching peaks of 0.878 mg/L during the wet season and 0.578 mg/L during the dry season. The low-phosphate detergent scenario reduced TP concentrations by up to 58%, while the partial technical reduction scenario lowered concentrations close to the water quality standard even under low-flow conditions. Survey results indicated that all respondents were willing to adopt environmentally friendly detergents. The findings suggest that the combination of low-phosphate detergent use and partial technical TP reduction has the potential to become an effective management strategy for reducing phosphate pollution in urban drainage channels.
