This concrete structure in the river is a flume with a narrower section at its upstream end, designed to constrict the flow of water in a flood event. When a flood occurs water backs up behind the constriction and overtops a low section of bank further upstream, flowing into a large flood storage hollow set aside for that purpose next to the river. The flood water is then let down in manageable quantities through residential areas downstream.
