Abstract

The drainage concept common mistake that often occurs is dumping stagnant water into the river which will exceed the river's capacity, resulting in flooding. The eco drainage system can be a more environmentally friendly solution by absorbing as much surface runoff as possible into the soil naturally or channeling the water into rivers without exceeding the river's capacity limits. This research aims to determine how much water runoff is on sloping land, the effectiveness of the eco drainage method in controlling water runoff and its effect in increasing soil infiltration on sloping land. This experimental research was tested using a Rainfall Simulator with slopes of 13° and 20° and dead-end drainage holes. On a land slope of 13⁰ with rainfall of 3.67 L/minute, the amount of runoff with dead-end drainage is 3.71 L/minute and without which is 4.14 L/minute. Meanwhile on a land slope of 20⁰ with rainfall of 3.99 L/minute, the amount of runoff with dead-end drainage is 8.4 L/minute and without which is 9,63 L/minute. Providing dead-end drainage on sloping land can reduce the speed of surface runoff which will then enter the soil in the form of infiltration water.

Abstract

Sungai adalah aliran air di permukaan bumi yang terbentuk secara alami, mulai dari hulu kecil hingga hilir besar. Transportasi sedimen, sebagai proses alami yang melibatkan pergerakan material sedimen di sepanjang sungai, dapat berdampak cukup besar pada morfologi sungai. Keberadaan sedimen yang terlalu banyak dapat mempengaruhi perubahan morfologi seperti perubahan bentuk aliran dan kedangkalan di sungai, yang dapat menyebabkan air meluap yang dapat menyebabkan bencana banjir setiap tahunnya. Dalam banyak kasus yang ditemukan di Kabupaten Bantaeang, Sungai Calendu mengalami perubahan morfologi yang signifikan akibat sedimentasi yang terlalu tinggi. Tujuan dari penelitian ini adalah untuk mengetahui seberapa banyak transportasi sedimen dan pengaruh sedimen terhadap perubahan aliran Sungai Calendu di Kabupaten Bantaeng. dan hasil yang diperoleh untuk metode USBR, kejadian pengangkutan sedimen terapung sebesar 13,85 ton/tahun dan total pengangkutan sedimen terapung dengan debit desain Q50 sebesar 178,52 ton, pengangkutan sedimen dasar menggunakan metode Mayer Petter Muler sebesar 1903,72 ton/tahun, Einstein 78,70 ton/tahun, dan berdasarkan data lapangan sebesar 56,22 ton/tahun.

Abstract

The Katingan watershed in Central Kalimantan Province, Indonesia, has experienced land use changes that have led to a reduction in the groundwater recharge areas. This study aims to examine the hydrological response of the Katingan watershed due to land cover changes by simulating the discharge of the Katingan River in Kasongan using the Arc-SWAT model integrated with Geographic Information System or GIS. The calibration results showed that the dominant physical parameters influencing the model were CN2 and ALPHA_BF. The CN2 value increased from 80 in 2013 to 83 in 2022, indicating a decrease in recharge areas and an increase in surface runoff volume. Meanwhile, the ALPHA_BF value remained 1 for all calibration years, indicating no significant changes in groundwater volume. The best-performing model was found for the calibration and validation years 2022 and 2023, indicating that land cover changes had a significant impact on the hydrological response of the Katingan watershed

Abstract

Flooding in the residential areas of Palangka Raya City has become more frequent, including in the neighborhoods around Jalan Pangeran Samudera. A viable approach for managing flood risks is the use of rooftop rainwater harvesting. The objective of this study is to model the effects of implementing a rooftop rainwater harvesting system in these residential areas on the flow of the main drainage system. The study was conducted in 2024 using a simulation approach. The data used includes maximum daily rainfall, the drainage network and its flow directions, as well as the roof areas of buildings around Jalan Pangeran Samudera. The Rational Method was employed to analyze the discharge both without and with the rainwater harvesting scenario. The research findings show that, for return periods of 2 to 20 years, the drainage discharge without the implementation of the rooftop rainwater harvesting scenario ranges from 4.414 m³/second to 7.396 m³/second. Meanwhile, with the implementation of the rooftop rainwater harvesting scenario, the drainage discharge is estimated to range from 1.847 m³/second to 3.095 m³/second. In other words, for return periods of 2 to 20 years, the implementation of the rooftop rainwater harvesting scenario is estimated to reduce the drainage discharge by between 2.566 m³/second and 4.300 m³/second. On average, the drainage discharge is expected to decrease by 58.15%.

Abstract

The Kampili irrigation system has experienced some damage, such as damage on channel body by ages, wild plants due to lack of maintenance and there are several channels that are not used to irrigate land according to the planned drainage area. The purpose of this study was to analyze secondary channel water loss and analyze the efficiency value of water distribution. This research was held on September 2024 and analyzed using the experimental methods. The results showed that the level of efficiency of the secondary channel was 79% which was still in the good category. That means it still functions well to channel water to the tertiary channels in Pallangga Village. This level of efficiency is supported by the physical structure of irrigation which also still in a good condition. In addition to water loss due to seepage, water loss was also caused by evaporation of 0.004209 m3/s but the level of efficiency still in standard.
