Penentuan Debit Lingkungan Di DAS Dodokan Berdasarkan Metode Tennant Dan Flow Duration Curve (FDC)

The Dodokan Watershed (DAS) is a watershed that included in one of the national priority watersheds, so it necessary to monitor and evaluate management on regular basis. One very important aspect monitoring evaluating determination amount environmental discharge. Environmental discharge Indonesia known as river maintenance flow which intended context maintain ecosystems. regulated PP No. 38 2011 concerning rivers, namely Q95% mainstay purpose this study was determine efforts future. method used hydrological method, Tennant duration curve (FDC). recommends minimum set relative annual average FDC daily data processed into certain percentage probability value event using Weibull theory. results showed interval methods 0.01–0.2 m3/s, from can be seen characteristics have small quantity. This situation illustrates carrying capacity declining condition carry out proper accordance with existing conditions
