Abstract: An intake for drawing make up water of about 2.8 cu. m/s for the cooling water system of 1840 MW Super Thermal Power Project was proposed to be located in the deep channel hugging the right bank of Ganga river at Kahalgaon which is downstream of Patna. On the basis of studies conducted in a 1:60 geometrically similar scale partwidth model, suitability of location and orientation of the intake were assessed and local protection in the vicinity of the intake was suggested. A tendency for the main channel to shift away from the right bank was observed. Studies were, therefore, conducted on a comprehensive model constructed to a horizontal scale of 1:500 and vertical scale of 1:70 for evolving suitable river training measures to peg the main channel along the right bank at the location of the intake. On the basis of model studies, three permeable spurs along the left bank upstream of the intake were suggested to make the existing branch channels heading towards the right bank more active.
