<![CDATA[Curah hujan yang tinggi menyebabkan terjadinya luapan di Sungai Remu merupakan salah satu penyebab terjadinya banjir di Kota Sorong. Terjadinya banjir di sekitar Sungai Remu disebabkan banyak faktor juga, salah satunya perubahan tata guna lahan di bagian hulu yang mengalami perubahan menjadi lahan pertanian, dan juga kegagalan penampang yang ada tidak bisa menampung air yang menyebabkan banjir. Maka dengan adanya hal tersebut perlu dilakukan analisis rambatan banjir Sungai Remu menggunakan aplikasi Zhong Xing HY21. Analisis ini membutuhkan perhitungan hidrologi dan statistika untuk memperoleh debit banjir rencana. Penggunaan metodenya dengan Hidrologi Satuan Sintesis Nakayasu dengan Q25 th. Setelah mendapatkan debit banjir rancangan, kemudian dilakukan analisis rambatan banjir menggunakan aplikasi Zhong Xing HY21. Berdasarkan hasil analisis tersebut, didapatkan seluruh desa tergenang banjir dengan total luasan banjir 2.183 km2. Sehingga dibuatnya Rencana Tindak Darurat sangat penting dengan membuat kelas prioritas dengan urutan evakuasi yaitu, Remu Selatan, Remu Utara, Malamso, Remu, Malawei, Malabutor, dan Malaingkedi.High rainfall causes overflow in the Remu River which is one of the causes of flooding in Sorong City. The occurrence of flooding around the Remu River is also caused by many factors, one of which is the change in land use in the upstream area which has changed to agricultural land, and also the failure of the existing cross section to not be able to accommodate water which causes flooding. So with this, it is necessary to analyze the flood propagation of the Remu River using the Zhong Xing HY21 application. This analysis requires hydrological and statistical calculations to obtain the design flood discharge. The use of the method with the Nakayasu Synthesis Unit Hydrology with Q25 th. After getting the design flood discharge, then a flood propagation analysis was carried out using the Zhong Xing HY21 application. Based on the results of the analysis, it was found that all villages were flooded with a total flood area of 2,183 km2. So it is very important to make an Emergency Action Plan by making priority classes in the order of evacuation, namely, South Remu, North Remu, Malamso, Remu, Malawei, Malabutor, and Malaingkedi.]]>
