Flood Discharge Analysis Using the SCS Hydrograph Method in the Krung Tripa Watershed

The purpose of this study was to analyze the flood discharge of the krung Tripa river re-period plan and flood behavior based on hydrographic data obtained from rainfall data and estimate the magnitude of peak flood discharge. Flooding is the main problem caused by the overflow of Krung Tripa, with administrative Krung Tripa passes through 2 (two) districts in Aceh Province, namely in Nagan Raya regency in the area of the watershed (DAS) reached 3472.95 Km. Several factors cause flooding, including slope factors and land height of an area, soil type factors land uses. The method used to analyze flood discharge is the Scs Hydrograph method using  secondary data. The results of flood discharge analysis obtained flood discharge plans for a 2-year re-period of 2464.033 m3/s, a 5-year re-period of 3597.893 m3/s, in are-period of 10 year obtained the planned flood discharge for a 2-year re-period was 2464.033 033 m3/s, 5-year re-period 3597.893 m3/s, in the 10-year re-period 4372.634 m3/s, in the 25-year re-period 5377.98 m3/s, in the 50-year-old period 6153.054 m3/s, in the 100-year-old re-period 6946.462 m3/s.
