Abstrak. Luas Sub DAS Krueng Jreue 23.218,06 Ha dan Khee 9.599,66 Ha. Berdasarkan hasil kajian bahwa luas vegetasi tutupan lahan semakin berkurang setiap tahunnya dimana ditandai dengan tingginya nilai fluktuasi debit sehingga mengakibatkan banjir pada musim hujan kekeringan kemarau. Tujuan penelitian adalah untuk mengetahui ambang batas hidrologi di indeks Khee. Penelitian ini menggunakan metode ranking Weibull ditentukan Q50 Q80, dihitung defisit durasi kemudian hidrologi. Nilai 0,067 m3/s 0,181 m3/s. Defisit tahun 2014 tertinggi angka 0,401 kering tujuh bulan 2012 -0,715 enam bulan. Indeks 2015 0,0629 sub 2011 0,3282 m3/s.An Analysis of The Aceh’s Hydrological Drought Index (A Case Study Watershed and Khee)Abstract. area the Sub-watershed is 23,218.06 9,599.66 Based on results study that land cover vegetation decreases every year which indicated by high value discharge fluctuations, resulting in flooding rainy season drought dry season. purpose this was to determine threshold for hydrological Sub-watersheds index Sub-watersheds.
