Abstract
Desang is a perennial tributary of the River Brahmaputra in India. This tributary originates in the foothills of Arunachal Himalaya and confluences in the southern part of the River Brahmaputra. The Stage-Discharge Rating Curve has been prepared based on the Stage and Discharge information of the year 1995. This rating curve is used for discharge estimation based on stage data of 19 years, from the year 1994 to 2012. Equation of power regression is used, as it is the ‘Best Fit’ relationship, for this river to assess the Micro Hydropower harnessing potentialities. Desang is found to had have maximum annual discharge of around 7,547million cumec in the year 1995 and minimum annual discharge of around 3,977 million cumec in the year 2001. Based on the stage discharge rating curve, the daily discharge of 6,942 days is estimated before preparing discharge hydrographs. The flow duration curve is prepared for the stream along with assessing possible power generation potentialities at different head situations in the stream. The flow duration curve reveals that the Desang has enough discharge to produce more than 2.5 MW run-of-the-river electricity with 90% excedence at any geologically conducive point of 10 metres head.
