The project involved the transformation of a straight, uniform, steeply embanked, trapezoidal river channel into a morphologically diverse, oxygenated and habitat-rich river channel. Key improvements made to the river here include increased floodplain connectivity, greater variety in channel depth and width and enhanced flow velocities (to accelerate geomorphic change).
