Abstract

The drainage system in Malang City currently relies on the Sengkaling Kiri irrigation network to discharge urban drainage water. However, the existing channel capacity is insufficient to accommodate the increasing water flow during rainfall events due to channel narrowing and sedimentation. This limitation has resulted in frequent waterlogging and localized flooding, particularly around Jl. Soekarno Hatta, Jl. Ahmad Yani, and Jl. Lt. Gen. Sutoyo. This research aims to evaluate the performance of the current drainage system, identify the primary causes of flooding, and propose effective solutions to reduce inundation in these critical areas. The study employs a descriptive and analytical approach, combining field surveys, hydrological data collection, and hydraulic modeling to assess the channel’s capacity and identify critical points of overflow. The findings reveal that the current Sengkaling Kiri irrigation network has experienced significant sedimentation and reduced cross-sectional area, leading to a capacity deficit during peak discharge events. Proposed solutions include channel widening, sediment removal, and the construction of alternative drainage routes, such as diverting part of the flow directly from the Sengkaling Kiri network to the nearest Sungai Brantas. These interventions are expected to significantly reduce waterlogging and improve flood management in the affected areas. The implications of this study highlight the importance of regular maintenance, capacity upgrades, and the integration of urban drainage systems with natural waterways to ensure long-term flood resilience in rapidly developing urban areas.

Abstract

DAS Welang merupakan salah satu DAS terbesar yang menjadi pemasok kebutuhan air baku dan irigasi untuk daerah Pasuruan. Namun, pada DAS Welang terjadi permasalahan hilangnya data curah hujan sehingga tidak dapat menghitung debit andalan yang terjadi pada DAS Welang. Alternatif untuk melengkapi data curah hujan yang hilang adalah menggunakan data curah hujan dari satelit, salah satunya satelit yang diluncurkan oleh NASA, yaitu Global Precipitation Measurement (GPM). Data curah hujan dari satelit GPM yang telah terkoreksi akan digunakan sebagai input data hujan pada pemodelan National Rural Electric Cooperative Association (NRECA) untuk menghasilkan estimasi debit pada DAS Welang. Analisis kalibrasi data curah hujan satelit GPM menghasilkan nilai NSE sebesar 0,843 kategori “Sangat Baik” dan nilai Koefisien Korelasi sebesar 0,919 kategori “Sangat Kuat”. Pemodelan metode NRECA untuk analisis kalibrasi dan validasi menunjukkan bahwa nilai NSE dan Koefisien Korelasi paling baik dihasilkan oleh komposisi data kalibrasi dan validasi 19:1 dengan nilai NSE untuk kalibrasi sebesar 0,952 kategori “Sangat Baik” dan untuk validasi sebesar 0,627 kategori “Memenuhi”, sedangkan nilai Koefisien Korelasi untuk kalibrasi sebesar 0,983 kategori “Sangat Baik” dan untuk validasi sebesar 0,807 kategori “Sangat Kuat”. Perhitungan debit andalan, hasil yang didapatkan untuk Q80% sebesar 2,63 m³/dt, untuk Q90% sebesar 2,11 m³/dt, dan untuk Q95% sebesar 2,01 m³/dt.

Abstract

Rainfall data is crucial in water resources management, particularly associated with its quantity, quality, and spatial and temporal availability in a basin. This study aims to assess the feasibility of Global Precipitation Measurement (GPM) satellite rainfall data to represent rainfall in the Wampu basin. The observed and the GPM rainfall data were collected for 2001 – 2022. Rainfall data from observations and satellites are classified into seven rainfall depth classes with an interval of 10 mm for each class. The GPM was calibrated by determining each class’s correction factor (CF). Calibration is carried out by adjusting the CF value until the difference between the probability of occurrence of satellite and observation data for 2001 – 2017 shows a minimum value. The accuracy of the yielded CF was then validated by evaluating the estimated rainfall from the GPM with the observed rainfall for 2018 – 2022. The results show that the CF of GPM varies from 0.9 – 1.012 for rainfall intervals 0 – 10 mm, 10 – 20 mm, 20 – 40 mm, 40 – 50 mm, 50 – 100 mm, 100 – 110 mm, and >110 mm, respectively. Then, the validation results show an “Excellent” level of accuracy between the corrected GPM and the observed data.

Abstract

The temporal distribution of rainfall plays a vital role in hydrological analysis, particularly in estimating peak flood discharge, which significantly impacts the design of flood control infrastructure. Understanding rainfall distribution patterns is essential for improving flood forecasting and water resource management. This study aims to compare the rainfall distribution patterns in the Jatigede Watershed (DAS Jatigede) using the Huff Quartile 1 to 4 method. Hourly rainfall data were collected from six rainfall stations: Bayongbong, Cikajang, Darmaraja, Jatigede, Leuwigintung, and Sadawangi, with Ground Station data used for validation. The analysis revealed that rainfall in the Jatigede Watershed is steeper than Huff Quartile 1, with peak intensity occurring earlier during events, indicating a high concentration of rainfall at the beginning of storms, which may affect flood peak formation and watershed response time. These findings underscore the need to adjust hydrological models to better reflect actual rainfall distribution. However, the study has limitations, including a relatively small number of observation stations, potential inaccuracies in rainfall measurements, and the Huff method’s limited ability to capture spatial rainfall variability. Addressing these limitations in future research is essential for enhancing flood risk assessment and hydrological modeling accuracy in the Jatigede Watershed.

Abstract

A process of converting rain data to runoff or discharge flow is called the rain transformation process. The transformation of rain into discharge is affected by the physical characteristics of the watershed and its land used. Discharge data in a watershed functions is as a measure of the amount of discharge available in a river which is useful in improving the management of water resources. This study purpose is to determine the results of the calculation of rain to discharge which located in the Metro DAS, Malang Regency. The methods analyzed by researchers is the FJ. Mock and NRECA methods. The results of the calculation from these methods are then compared with the rain data, because the AWLR discharge in the Sub Metro Watershed is considered not suitable to be the discharge of observations in this study. Based on the analysis results, the most suitable method for calculating the rainfall discharge in the Sub Metro Watershed is NRECA method with a determination coefficient (R2) = 0.792, and a correlation coefficient (r) = 0.887.

Abstract

Urban surface flooding has become a recurrent problem in rapidly urbanizing cities in Indonesia, including Malang City. The Lowokwaru District, as an educational and residential hub, frequently experiences inundation during moderate to high rainfall events, indicating potential inadequacy in its urban drainage system. This study aims to evaluate urban drainage capacity in relation to surface flooding in Lowokwaru District through a comprehensive synthesis of empirical studies, modeling-based evaluations, and spatial analyses conducted over the past decade. A qualitative-descriptive and comparative approach was employed by reviewing and integrating results from peer-reviewed journal articles that applied hydrological–hydraulic analysis, EPA SWMM modeling, GIS-based evaluation, and eco-drainage concepts. The results indicate that a significant proportion of drainage channels in Lowokwaru are unable to convey design flood discharges for 5- to 10-year return periods due to insufficient channel dimensions, sedimentation, debris accumulation, and rapid land-use change. Several studies demonstrate that structural improvements alone are insufficient; instead, integrated solutions such as Low Impact Development (LID), infiltration wells, detention ponds, and eco-drainage strategies can reduce surface runoff and flooding by 40–70%. This study concludes that urban drainage management in Lowokwaru requires a systemic and sustainable approach that integrates hydraulic capacity enhancement with land-use control and nature-based solutions. The findings provide a consolidated scientific basis for urban flood mitigation planning in Malang City and similar rapidly urbanizing areas.
