Flooding occurs every rainy season on Air Bersih Street, which crosses Medan Kota and Medan Denai Districts. Rainwater tends to pond on the road surface rather than flow into drainage channels, indicating an imbalance between runoff discharge and channel capacity. This study aims to evaluate the capacity of existing drainage channels and identify the factors affecting their performance. Field surveys were conducted on 12 segments along ±3 km to measure channel width, depth, length, and sediment thickness. Maximum rainfall data for 2014–2023 from BMKG were analyzed using the Gumbel distribution and Mononobe method. Domestic wastewater discharge was calculated based on population data.The results show severe sedimentation with a total sediment volume of 780.3 m³. The planned runoff discharge reaches 2.51 m³/s, while domestic wastewater contributes only 0.086 m³/s (3.3% of total discharge). Comparison between total discharge and channel capacity indicates that only segment 10 has sufficient capacity (2.79 m³/s > 2.60 m³/s), while the other segments are inadequate. The main causes are lack of routine dredging, improper waste disposal, and insufficient channel dimensions. Therefore, immediate channel normalization, periodic sediment dredging, and public awareness on waste management are strongly recommended.

This study aims to evaluate the performance of the drainage system in the Jalan Suluh – Jalan Pembangunan III corridor in Medan City based on surface runoff discharge. The main problem that occurs is waterlogging during high-intensity rainfall due to inadequate channel capacity. The methods used include rainfall analysis using the Log Pearson Type III distribution, rainfall intensity calculations using the Mononobe method, runoff discharge calculations using the rational method, and channel capacity analysis using the Manning equation. The data used were rainfall data for the 2016–2023 period and direct field measurements. The results showed that the maximum runoff discharge of 1.63 m³/second was greater than the capacity of most drainage channels. Of the eight segments analyzed, only one segment met capacity, while the other seven segments were unable to accommodate the flow discharge. Based on these results, it can be concluded that the drainage system at the study site is not functioning optimally and requires improvements in the form of channel normalization and redesign of channel dimensions.

Urban drainage systems are crucial for managing surface runoff and preventing flooding in densely populated areas like Medan. However, rapid urbanization, population growth, and sedimentary layers often reduce the hydraulic capacity of these channels, which can lead to local flooding. The purpose of this study was to examine the geometric characteristics and sedimentation conditions of the drainage channels on Jalan Alumunium Raya Medan. This study used a descriptive-evaluative method that combined field surveys for primary data on nine observation segments with secondary data analysis in the form of rainfall and population statistics. The study found significant sedimentation with a height of up to 0.8 m, reducing the effective capacity of the channel.Geometric measurements indicate that the channel is between 1.0 and 1.55 meters wide and 0.45 and 1.4 meters deep. Analysis indicates that the projected population of 37,050 by 2025 and high annual rainfall (2,100–2,600 mm) both increase the amount of runoff the system must handle. The total sediment volume is 1,359.23 m³, and the flow rate is 1.94 m³/s. In conclusion, the current drainage system is not functioning properly and can cause flooding. To restore the effective capacity of the channel and ensure long-term urban water management, regular maintenance, sediment dredging, and normalization of the channel dimensions are essential.

Urban drainage systems play an important role in managing stormwater runoff in urban areas. Rapid urban development often reduces infiltration areas and increases surface runoff, which can lead to flooding and waterlogging in several locations. This study aims to analyze the performance of urban drainage systems and identify factors causing water inundation in urban areas. The research method used is a descriptive quantitative approach by evaluating drainage channels based on rainfall data, channel capacity, sedimentation conditions, and supporting environmental factors. Secondary data were collected from previous studies and hydrological analysis results. The analysis includes rainfall intensity calculation, runoff discharge estimation, and comparison with existing drainage channel capacity. The results show that several drainage channels are unable to accommodate the design discharge due to sedimentation, waste accumulation, and changes in land use. In addition, insufficient maintenance of drainage channels also contributes to the reduced performance of the drainage system. Therefore, improvements in drainage channel capacity, routine maintenance, and integrated urban drainage planning are needed to reduce flood risks in urban areas. The results of this study are expected to provide useful information for local governments in improving urban drainage management systems.

The rapid population growth, projected to reach 151,340 people by 2026, significantly increases the burden on urban infrastructure. This study aims to evaluate the adequacy of the existing drainage channel capacity in coping with a 50-year return period rainfall of 3,861 mm. The methodology employed is field research using a quantitative approach through direct observation and measurement at the study site. Hydrological analysis was conducted by accounting for an evapotranspiration factor of 60% to obtain accurate runoff values. The results indicate that water flow efficiency is severely hindered by sediment accumulation, with the highest sediment volume reaching 728.26 m³ and a thickness of 0.41 m. Technically, the current channel dimensions are only safe for a return period of ≤10 years. Therefore, strategic measures are required, including channel redesign and periodic sediment dredging management, to ensure long-term safety and minimize flood risks for the community.

This study aims to examine the sedimentation condition in drainage channels located in Medan Johor District, Medan City, and to analyze its impact on channel flow capacity. The background of this research is the decreasing performance of drainage systems due to the accumulation of sediments originating from surface runoff, community activities, and solid materials transported by rainwater. The method employed in this study is a field survey involving direct measurements of channel dimensions, including length, width, depth, and sediment thickness at several observation points. The collected data were processed to estimate sediment volume using a geometric calculation approach. The analysis results indicate that the total sediment volume across seven observation segments reaches 2,180.75 m³, reflecting a relatively high level of sedimentation. This condition leads to a reduction in channel capacity, resulting in suboptimal water flow. Furthermore, population growth contributes to increased domestic wastewater entering the drainage system. If not properly managed, this situation may increase the risk of waterlogging and flooding. Therefore, sustainable drainage management and regular maintenance are essential to improve system performance.

Urban drainage systems play an important role in channeling rainwater and household wastewater so that they do not cause puddles or flooding in residential areas. Along with the increasing development and land use in urban areas, the capacity of drainage channels is often unable to accommodate the existing water discharge. This study aims to analyze the capacity of drainage channels located on Taduan Street, Medan Tembung District, and to determine their suitability for the existing rainfall discharge. The research method used is a quantitative method with data collection through field surveys to measure the dimensions of the drainage channels and collect rainfall data. The data were then analyzed to calculate the rainfall discharge and the capacity of the existing drainage channels. The results show that several parts of the channels experience sedimentation, narrowing, and the presence of household waste that obstructs water flow. These conditions reduce the capacity of the channels so that they are unable to accommodate water discharge optimally. Therefore, routine maintenance and improvement of channel dimensions are needed so that the drainage system can function more effectively in reducing water inundation.
