River channel restoration and natural flood management opportunities within the Garrell Burn catchment were investigated by cbec as part of the wider Dumbreck Local Nature Reserve and Garrell Burn restoration project led by WSP and commissioned by North Lanarkshire Council
An initial desk-based and geomorphological walkover were undertaken by cbec and used to determine the reference condition of the lower Garrell Burn, with restoration opportunities for the lower section of the burn then identified and appraised, considering this information in addition to site constraints. cbec supported WSP with the production of detailed designs, which included realignment of an approximately 450 m section of the burn that was significantly straightened and canalised, advising on appropriate channel geometry and relevant features to be implemented within the new design channel. cbec also led the design of several in-channel large wood structures, which were included within the design to promote flow diversity and habitat.
Construction of the realigned section of burn was completed in 2021, with cbec providing design site supervision at key stages of the build. In November 2022, the project was nominated as a finalist in the RSPB Scotland’s Nature of Scotland Awards and was Highly Commended in the Nature and Climate Action category.
