The wall section comprises a flexible barrier membrane 40 having a first portion 42 fixed at or vertically adjacent to the trough section and one or more float members 50 which co-operate with the flexible barrier membrane such that the flexible barrier membrane is in tension when the wall section is at the second position. |
