Abstract

Data used in this case study, rainfall data (mm), temperature (ᵒC), humidity (%), duration of sun exposure (hours), wind speed (m / s). Data collection methods used in this study include, primary data obtained directly by conducting field research using Davis Vantage VVE 6250 Wireless Weather Station. And secondary data is obtained online from the official website data onlineBMKG.go.id. by taking data from 2010 to 2019 in a period of 10 years. With research locations: Mandiri Station, Lambaro Skep, Kuta Alam, Banda Aceh City. Class I Meteorological Station, Sultan Iskandar Muda, Aceh Besar. Meteorological Station Class IV, Lampanah Teungoh, Indrapuri, Aceh Besar. Cot Ba'u Class III Meteorological Station, Sukajaya, Sabang City, Aceh. Malikul Saleh Meteorological Station, Lhoksmawe, North Aceh. Cut Nyak Dhien Meteorological Station, Nagan Raya. Frequency analysis parameters include the parameter average value, standard deviation (Sd), coefficient of variation (Cv). Kurtosis Coefficient (CK) Calculation of these parameters is based on the record of the average daily rainfall of the maximum maximum of the last 10 years. Analysis of rainfall frequency distribution and birthday period (PUT). Analysis of Normal Distribution, Normal Log Distribution, Pearson Type III Log Distribution, Gumbel Distribution, and for analysis methods using isohyet methods, and arithmetic.

Abstract

Krueng Pandrah River was analyzed by cross section of a trapezoid-shaped river. To determine the capacity of river cross section capacity, it is necessary to do hydraulic modeling. From the results of modeling using HEC-RAS 5.0.5 1-dimensional flow stated that the Krueng Pandrah River with a trapezoid-shaped river cross section width of the river is 10.00 m, depth of 6.00 m, slope of the talud 1V: 1.5H and safe from flooding. The construction used to repair cliffs and river channel is River Revetment which is made of stone structure with a weight of 650 - 800 Kg / Unit. River Revetment Height is planned to be 6.00 m from the river bed, slope 1H: 1.5V, width of 2.50m Revetment gaiters, and 1.30 m thick rock layer. To maintain the stability of the Revetment against the decline and scouring that might occur behind it, a Non Woven Geotextile layer was installed as wide as the surface of the stone layer along the Revetment. For handling, river management, river normalization and flood mitigation, the flood return period used in this analysis is Q5 years of 163.02 m3 / sec.
