Abstract

Water offers many advantages that are essential for the preservation of human existence. Excessive quantities of water, such as flooding, can negatively impact human beings. The land utilization within a watershed (drainage area) plays a crucial role in the frequency and impact of flooding events. Instances of land use changes that resulted in flooding happened in the Bang Sub-watershed, located in Malang Regency. A comprehensive and up-to-date examination of flood management solutions is required. This study seeks to offer technical suggestions for flood management in the Bang Sub-watershed due to land-use alterations, utilizing the HEC-RAS software. Integrated treatment solutions are provided to mitigate the potential damage caused by future flooding. The flood simulation yielded recommendations for mitigating the impact of future floods. These recommendations include the construction of a retarding basin in the upper part of the river with a capacity of 1.4 million m3, as well as the construction of a 654 m long river embankment that is 50 cm. The alteration of the land leads to a decrease in the cross-sectional capacity of the river at the mouth of the Bang River, resulting in annual flooding occurrences. A non-technical approach to enhance the quality of the watershed is implementing reforestation measures to decrease the runoff coefficient.

Abstract

Road damage in the UB Forest Sumberwangi Area, Karangploso District, Malang Regency, is one of the harmful impacts of the drainage system. This study aims to analyze an accurate and efficient drainage system by applying modern methods, namely Building Information Modeling (BIM). By using BIM, the analysis of drainage work becomes faster and more accessible than with conventional methods. BIM is beneficial in building and analyzing drainage network data quickly and effectively and can help expand it to provide more accurate results. BIM can integrate models based on technical data and simulate development information into a three-dimensional model. BIM is used to perform 3D modeling of drainage channels using Autodesk Civil 3D, as well as analyzing channels from both hydrology and hydraulics with Storm and Sanitary Analysis (SSA). After calculating the design for a 5-year return period rainfall, channel dimensions of 50 x 50 cm and 30 x 30 cm were obtained. Based on the hydraulic analysis, it is known that several points have velocities that exceed the maximum velocity for the concrete surface (v < 3 m/s), so it is necessary to build a drop structure with h = 1 m. The quantity take off and the volume are calculated by Civil 3D for cut and fill work 7824.07 m3 and 1389.79 m3, respectively.

Abstract

Flooding in the Ngotok Ring Canal is a recurring problem, primarily caused by intense rainfall, elevated water levels of the Brantas River, and the limited capacity of the canal's flow. This issue is especially evident at the confluence points of the Ngotok Ring Canal with its tributaries, where backwater effects or puddling occur. The objective of this study is to analyze the flood dynamics in the Ngotok Ring Canal, specifically evaluating the rise in floodwater levels and necessary mitigation measures. The analysis was conducted using the HEC-RAS program to model existing river conditions and assess flood risks. The study identifies that the embankment height at the upstream section of the Ngotok River is insufficient to contain the flood discharge, leading to overflow into surrounding agricultural fields. The flood design for the Ngotok River, based on a 25-year return period, was determined to be 866.29 m³/sec. The proposed solution involves an economical embankment design with a 1:1.25 slope, ensuring that the floodwater level remains below the average land elevation. This design approach addresses both floodwater containment and cost-efficiency in construction, providing a sustainable solution to reduce flooding risks in the area.
