“…Berkurangnya daerah resapan air menyebabkan peningkatan limpasan (runf off) pada musim hujan (Jumhasla Putra et al, 2018). Air Hujan yang jatuh sebagai salah satu bagian dari siklus hidrologi akan terintersepsi, sebagian akan terinfiltasi pada wilayah yang masih hijau dan akan menjadi limpasan (runf off).…”

Abstrak. DAS Citanduy merupakan salah DAS yang terbesar di pulau Jawa dengan sungai utama adalah Cintanduy. DAS Citanduy terdiri dari beberapa sub DAS, salah satunya adalah sub DAS Citanduy Hulu. Perubahan tata guna lahan di DAS Citanduy Hulu terus terjadi, kondisi tsb telah mengakibatkan peningkatan debit banjir di sungai. Peningkatan debit di sungai diakibatkan adanya limpasan permukaan akibat hujan. limpasan permukaan dapat dianalisis menggunakan metode SCS (Soil Conservation Service). Metode SCS juga dianalisis berdasarkan kondisi tanah, sehingga dapat menentukan nilai Curve Number (CN) dari lahan. Hasil analisis tahun 2018, menunjukkan bahwa tutupan lahan 18,99% atau 13.735,97 ha berupa hutan (hutan primer, sekunder dan hutan tanaman). Sebaran jenis tanah di umumnya adalah Typic Dystrudepts (36,57%) dan Typic Hapludands (37,93%). Hydrological Soil Group (HSG) di DAS Citanduy Hulu didominasi oleh klas B sebesar 76, 92 %. Hasil analisis didapatkan bahwa DAS Citanduy Hulu tebal runoff maksimum pada PUH 2, 5, 10, 25, dan 50 tahun secara berurutan adalah 104 mm, 133 mm, 147 mm, 171 mm dan 187 mm. Tebal limpasan permukaan minimum dengan PUH 2, 5, 10, 25 dan 50 tahun secara berurutan adalah 17 mm, 31 mm, 39 mm, 53 mm dan 64 mm. Tebal limpasan permukaan menunjukkan potensi peningkatan debit banjir.Analysis And Mapping Runoff In Watershed Upper Citanduy With SCSN MethodAbstract. Citanduy watershed is one of the largest watersheds on the island of Java with the main river being Cintanduy. The Citanduy watershed consists of several sub-watersheds, one of which is the Upper Citanduy sub-watershed. Changes in land use in the Upper Citanduy watershed continue to occur, this condition has resulted in an increase in flood discharge in the river. The increase in discharge in the river is caused by surface runoff due to rain. Surface runoff can be analyzed using the SCS (Soil Conservation Service) method. The SCS method is also analyzed based on soil conditions so that it can determine the Curve Number (CN) value of the land. The results of the 2018 analysis show that 18.99% or 13,735.97 ha of land cover is forest (primary, secondary and plantation forests). The distribution of soil types, in general, is Typic Dystrudepts (36.57%) and Typic Hapludands (37.93%). Hydrological Soil Group (HSG) in the Upper Citanduy watershed is dominated by class B by 76.92%. The results of the analysis showed that the maximum runoff thickness of the Upper Citanduy Watershed at PUH 2, 5, 10, 25, and 50 years respectively was 104 mm, 133 mm, 147 mm, 171 mm, and 187 mm. The minimum surface runoff thickness with PUH 2, 5, 10, 25, and 50 years respectively is 17 mm, 31 mm, 39 mm, 53 mm, and 64 mm. The thickness of the surface runoff indicates the potential for increased flood discharge.

Pasi Mesjid villages in Meureubo district are vulnerable to floods in the rainy season. Every year, the village was flooded and submerges many houses, rice fields, and plantation land owned by residents. The phenomenon of annual flooding is a concern for the local community because it causes material losses. Research on the flood discharge in the Meureubo watershed, Pasi Mesjid Village, was carried out to determine the amount of flood discharge with various return periods. The flood discharge calculation methods are using Melchior and Snyder. The scope of this study includes frequency analysis, rainfall design, flood discharge design by the Melchior and Snyder methods with return periods of 2, 5, 10, 25, and 50 years. The hydrological analysis results showed that the flood discharge values of the Snyder and Melchior methods were not much different, namely in the 2-year return period of 1607.77 m3/s. With the Melchior method, a 2-year return period obtained the plan flood discharge of 1813.286 m3/s, a 5-year return period of 2791.62 m3/s, a 10-year return period of 2938.14 m3/s, a 25-year return period of 3153.19 m3 / s, and a 50-year return period of 3336.5 m3/s. With the Snyder method, the 5 (five) year return period is 2374.710 m3/s, the 10 (ten) year return period is 2762.09 m3/s, the 25 year return period is 3284.96 m3/s, and for the 50 year return period, the value is 3699.18 m3/s. Based on this analysis results, the Snyder and Melchior methods can be used in analyzing the flood discharge in the Meureubo watershed area.

Floods that occur in Pasie Mesjid Village, Meurebo District, West Aceh Regency are increasing every year. This research was conducted to determine the risk factors that cause flooding and priority weights in an effort to minimize flood risk using the Likert Scale and AHP (Analytical Hierarchy Process) methods. The results of research using the Likert scale method show the perception of the people of Pasi Mesjid Village who live in the riverbank area that they need to relocate. The results of public perception became recommendations for 3 expert teams on Water Resources (SDA) PUPR, BPBD (Regional Disaster Management Agency) and the Expert Team from the Faculty of Engineering, Department of Civil Engineering, Teuku Umar University), by determining the priority weight for overcoming flood problems using the AHP method. Based on the research results, the analysis of the two methods shows that relocation is the most important thing in flood management efforts in Pasie Mesjid Village
