Captured sediment is retained behind in river structures such as checkweirs, with the aim of reducing downstream river pollution. Monitoring of these checkweirs is required to ensure a level is maintained to allow them to work to the best of their capability. To continue the monitoring that has been carried out over the past three to four years we are looking to source a supplier to provide long term monitoring to collate data relating to the accumulation of metal rich sediment including chemical analysis of the sediment, volume and particle sizing and impact of any scour of river banks in accordance with the detailed requirements within the scope The initial works will focus on three established checkweirs but may be expanded with the construction of new structures elsewhere in England.
