The river path going down to Warsash is built up on a causeway which protects the saltings and a wildlife area known as Bunny Meadow. To let the tide water in and out there are some large culverts which flow under the path.
The open end of the culverts create a whirlpool pretty much like a domestic sink as the tide flows out. We were walking along last week at just the right time to see them, about three or so hours after high water
