Abstract

Kali Gunting terletak di Kecamatan Mojoagung, Kabupaten Jombang yang memiliki panjang sungai ±10 Km dan luas daerah tangkapan air seluas ± 240,255 Km2. Saat musim hujan di Kali Gunting sering terjadi banjir. Banjir ini dikarenakan dimensi saluran tidak mampu menampung debit yang ada. Karena itu tujuan dari tugas akhir untuk mengetahui tindakan yang akan dilakukan untuk mengatasi banjir ini. . Tahapan Untuk mencapai tujuan tersebut adalah sebagai berikut. Pertama analisa hidrologi, yang meliputi: perhitungan distribusi perhitungan parameter statistik, perhitungan koefisien pengaliran, dan perhitungan hidograf satuan sintetik. Kedua analisa hidrolika dengan menggunnakan program bantu HEC-RAS Dari hasil analisis diperoleh, dengan debit periode ulang 10 tahun (Q10) yang sebesar 394 m3/dt terjadi banjir di Kali Gunting. Sehingga dilakukan pelebaran saluran di beberapa titik yang terjadi banjir. ================= Gunting river is located in Mojoagung Subdistrict, Jombang Regency which has long river ± 10 Km and wide catchment area of ± 240,255 Km2. When the rainy season in Kali Gunting often flood. This flood is due to channel dimension is not able to accommodate the existing discharge.Therefore the purpose of the final task to know what action will be taken to overcome this flood. Stages To achieve these goals are as follows. First is hydrological analysis, which includes: calculation of statistical parameter calculation distribution, calculation of drain coefficient, and calculation of synthetic unit hydrograph. Second is hydraulic analyzes using the HEC-RAS auxiliary program From the analysis results obtained, with a 10 year re-period discharge (Q10) which amounted to 394 m3/dt flooding occurred in Kali Gunting. So that the channel is widened at some point in the flood.
