Design and Implementation of the River Sheaf Comprehensive Flood-Alleviation Scheme

The River Sheaf Comprehensive Flood-Alleviation Scheme is a flood-defence scheme promoted by the Yorkshire Region of the National Rivers Authority. The scheme will improve 5.2 km of main river from a 1-in-5 year standard to a 1-in-50 standard at an overall cost of £3.1 million over the next four years. The hydrological, hydraulic and benefit/cost analyses have been carried out by the National Rivers Authority. Balfour Maunsell were commissioned to carry out the detailed structural design, prepare and administer contracts and supervise construction. The paper covers the preliminary design work and the detailed design of Phase I of the scheme.
