This tower is a 67 m high, reinforced and prestressed concrete structure with an oval cross-section measuring 17,5 m by 14,5 m. It stands in the upper reservoir straddling the waterway and is linked to the crest of the main Rockview embankment by a vehicular prestressed concrete access bridge. The large screen protected bellmouth at its base has been shaped with the aid of a hydraulic model to prevent flow separation and air entrainment into the waterway, an aspect descriptionbed in more detail in the paper by Kimpton and Gibson.
