Bow Back Riversとは 意味・読み方・使い方

The Bow Back Rivers are part of the River Lea in the London Borough of Newham, east London, England, and form a complex system of waterways. The River Lea was originally tidal as far as Hackney Wick; man-made changes to the river had changed this dramatically in the 9th century, and in 1110 a bridge was put in place at Bow. Over the ensuing centuries, the causeway that led to the bridge was cut by a number of man-made channels made to power water-driven tidal mills, such as those at Abbey Mills, and the still-surviving Three Mills. Further improvements to the channels were carried out in 1930 under the River Lee (Flood Relief) Act.
