A new report has highlighted the increasing challenges facing Scotland's hydropower sector due to climate change, particularly the impact of increased sediment buildup.

Commissioned by Scotland's Centre of Expertise for Waters (CREW), the report, published today, warns that climate change is expected to lead to a significant increase in sediment entering Scottish rivers, impacting the performance of hydropower facilities and potentially harming river ecosystems.

"The research highlights the complex balance that needs to be maintained between meeting Scotland's renewable energy needs and ensuring the environment is properly protected," said Professor Richard Williams, of the University of Glasgow's School of Geographical & Earth Sciences, who led the research. "While hydropower is vital for meeting climate change targets, care must be taken to minimise its impacts on river health and ecosystem."

The report, which was produced in collaboration with cbec eco-engineering and involved input from hydropower companies, Scottish Canals, SEPA, and NatureScot, outlines a series of recommendations to address these challenges.

These include measures to reduce sediment entering rivers, such as increased tree planting and peatland restoration, as well as improved sediment management practices at hydropower sites.

"We are delighted to see that the University of Glasgow and cbec eco-engineering have proactively taken steps to produce some excellent guidance material that will help operators in understanding the environmental importance of sediment and raise awareness on the importance of correctly managing sediment in a climate-changing world," said Dr Chris Bromley, Senior Hydromorphologist at SEPA.

The report also emphasizes the need for greater collaboration and knowledge sharing among stakeholders in the hydropower sector.
