River restoration design delivers cost savings for clients

We recently used a single hydraulic model early in the design process of our River Bain project, to allow two strands of work to be undertaken simultaneously. This reduced the risk of one design element impacting on another, in effect the flood risk modelling and assessment was undertaken as part of the hydraulic design. This approach led to cost savings for the client since only one model was used for the design and flood risk assessment processes.

The River Bain in Lincolnshire, where we have applied this approach, has been successful in securing planning permission for a scheme to create a new chalk stream channel, thanks to our work. The large stretches of the River Bain were culverted under farmland in the 1950’s which lead to a loss of valuable chalk stream habitat. Working for the Lincolnshire Chalk Streams Project we have taken the scheme from feasibility to detailed design, and through planning.

The creation of a 1D hydraulic model was used to assess the risk of silt deposition at low flows, channel stability under medium to high flow conditions and also the potential impact of the restoration on flood risk.
