Abstract

An effective drainage system in urban areas is essential to manage flooding caused by heavy rainfall. Inadequate drainage channels cannot accommodate excess water, leading to water stagnation and other negative impacts. Therefore, calculating the design flood discharge and designing drainage channels with sufficient capacity are crucial for stormwater management. This study aims to evaluate the capacity of existing drainage systems to handle design flood discharge and to design new drainage dimensions that can accommodate the largest discharge. The analysis shows that most existing drainage channels are unable to accommodate the design discharge (Qt) for return periods of 10, 20, 50, and 100 years, as the channel discharge (Qs) is smaller than the design discharge. Simulations using the Storm Water Management Model (SWMM) identified critical points at Junction 4 and Junction 10, where overflow occurs due to excess channel capacity. As a solution, new drainage dimensions were designed. A rectangular channel with a bottom width of 1.2 meters and a height of 1 meter can carry the discharge without overflow for a 100-year return period. Meanwhile, a trapezoidal channel with a bottom width of 0.25 meters, a height of 0.8 meters, and a side slope of 0.618 meters is also effective in accommodating the design discharge without overflow. This study recommends increasing the drainage capacity at critical points to reduce the risk of water stagnation

Abstract

Abstrak Banjir akibat air pasang atau banjir rob merupakan salah satu bencana yang sering terjadi di wilayah pesisir yang menggenangi bagian daratan di wilayah pesisir yang memiliki ketinggian (elevasi) lebih rendah dari muka air laut pasang tinggi. Kejadian banjir akibat pasang ini sudah memasuki area pemukiman penduduk di beberapa titik lokasi di Tarakan termasuk di sekitar kanal bandara Kota Tarakan. Berdasarkan pengamatan lapangan terdapat pemukiman warga di sisi kiri aliran kanal bandara Kota Tarakan, sehingga genangan mengganggu aktivitas warga. Berdasarkan permasalahan tersebut penelitian ini bertujuan untuk mengetahui tinggi muka air pada penampang kanal bandara Kota Tarakan akibat pasang surut dan banjir rancangan periode ulang 5 dan 10 tahunan. Metode yang digunakan untuk menganalisis tinggi muka air kanal bandara Kota Tarakan yakni menggunakan software HEC-RAS. Berdasarkan hasil analisis tinggi muka air menggunakan HEC-RAS diperoleh tinggi muka air penampang kanal bandara Kota Tarakan akibat banjir 5 tahunan dan 10 tahunan yang terjadi bersamaan dengan pasang tertinggi (HHWL) diperoleh tinggi muka air pada penampang sta 0+100 - 1+000 sebesar 3,8 m dan penampang 1+100 - 1+500 sebesar 3,81 m. Dari hasil penelitian ini maka disarankan pemerintah membangun pengendalian banjir dengan membuat tanggul dengan elevasi +4,5 m dari datum muka air terendah (LLWL). Kata kunci: Banjir rancangan, HEC-RAS, pasang surut, tinggi muka air,  Abstract Floods caused by high tides or tidal floods are one of the disasters that often occur in coastal areas that inundate the mainland areas in coastal areas that have lower elevations than the high tide sea level. The occurrence of tidal floods has entered residential areas at several locations in Tarakan, including around the Tarakan City airport canal. Based on field observations, there are residential areas on the left side of the Tarakan City airport canal, so the inundation disturbs the activities of the residents. Based on this problem, this study aims to determine the water level in the section of the Tarakan City airport canal due to tidal floods and floods with a 5-year and 10-year return period. The method used to analyze the water level of the Tarakan City airport canal is by using the HEC-RAS software. Based on the analysis results of the water level using HEC-RAS, the water level in the Tarakan City airport canal section due to a 5-year and 10-year flood that occurs simultaneously with the highest tide (HHWL) was obtained the water level at the sta 0+100 - 1+000 section is 3,8 m and the section of 1+100 - 1+500 is 3,81 m. From the results of this study, it is recommended that the government build flood control by constructing embankments with an elevation of +4,5 m from the lowest water level datum (LLWL). Keywords: Flood design, HEC-RAS, tides, water level,

Abstract

Climate change has a huge impact on the availability of water resources. Based on the case, this research is deemed necessary to do. Water availability is an essential issue related to climate change. The most perceived impacts due to climate change are climate anomalies; the rainy season lasts shorter with increasing intensity and the dry season lasts longer than usual conditions. The body of water cannot accommodate high-intensity rainwater, so it flows quickly into the sea. Relatively, a long dry season results in drought. The vulnerability of the availability of water sources in the Kalangkangan watershed, Tolitoli Regency was indicated through the reduction in river discharge. This changes in discharge had the potential to be difficult in meeting the needs of irrigation or clean water. If there is no attempt to protect and repair the water sources, it is believed that the reduction in discharge will continue until it hits a critical condition. The availability of water from the rain - discharge simulation model in the Kalangkangan watershed for wet conditions (Q20%) had a maximum discharge of 20.62 m³ / sec in June (decade II), and an average discharge of 13.59 m³ / sec. For normal conditions (Q50%) the maximum discharge was 19.47 m³ / sec in June (decade I), the minimum discharge was 5.35 m³ / sec in June (decade I) and the average discharge was 11.13 m³ / sec. For dry conditions (Q80%), the minimum discharge was 5.18 m³ / sec in May (decade I) and the average discharge was 9.05 m³ / sec
