Abstract


Krueng Meureudu watershed is a watershed whose carrying capacity must be maintained but in its development it has increased drastic river flow in the rainy season which is expected due to land conversion.This study aims to analyze the change of peak discharge and dependableflow discharge for two decades in Krueng Meureudu watershed Aceh Province. This descriptive research using Landsat image data and climatology data for top discharge count and debit mainstay using rational method and Mock model. The results of the Krueng Meureudu watershed study of Aceh Province have three sub-watersheds that have experienced peak discharge during the past two and a half decades by showing the highest peak discharge occurring in January, February, April, November and December with reliable dependableflow in Krueng Meureudu hilir sub-watershed period 2010-2015 is seen to experience fluctuations in unstable yearly discharge ranges from 3.44 - 4.82 m3 / s.
