Solution & Step-by-step Explanation
The primary objective of constructing the Farakka Barrage was to divert water from the Ganges River into the Hooghly River channel through a feeder canal. This was done to increase the water flow during the dry season, thereby flushing out silt accumulation and maintaining the navigability of the Kolkata Port. This corresponds to enhancing/raising the lean or lower flow into the Bhagirathi-Hooghly system.
