Abstract

Flow Duration Curve (FDC) is an important tool for various water related applications like hydro power generation, planning and design of irrigation systems, management of stream-pollution, river and reservoir sedimentation. Whenever adequate length of recorded data is not available, the FDC can be constructed to analyze the available stream flow data at the site. FDC provides the percentage of time (duration), a (monthly or seasonal) stream flow is exceeded over a recorded period for a particular river or stream. In this paper, statistical analysis is carried out to determine the series characteristics of stream flow data recorded at Farakka feeder canal. The stream flow data series for the months of March, April and May is independently used to construct FDCs for the respective months using empirical method. The study suggests that the dependable flow at different percentage levels viz., 75%, 90% and 100% obtained from FDCs can be used for planning of irrigation, hydro-power and drinking water projects in Farakka feeder canal.
