Marlow Weir. The weir is at left,with water flowing over it from left to right. A weir is a small dam used to control the level of a river. This weir has several levels,and a footbridge passing across it. A weir can increase the oxygen content of the water flowing over it,as is seen here with the foaming water (bottom). Boats navigate past the weir using a lock,in this case the nearby Marlow Lock (not seen),constructed in 1773. This weir is on the River Thames at Marlow,Buckinghamshire,England | |
