Assessment of erosion and sedimentation: What and how
Effective planning and operation of hydropower projects necessitate understanding and monitoring erosion and sedimentation. Key considerations during the preparation stage include hydrological data analysis, instream sediment monitoring, climate change predictions, impacts of surrounding reservoirs, and an assessment of the catchment condition. The integrity of the project’s slope stability and erosion risks, alongside robust sediment sampling… Read more

Water quality in deep reservoirs
Maintaining water quality in deep reservoirs of hydropower projects is complex due to stratification and oxygen depletion. Nutrient enrichment from agricultural runoff poses a challenge, but aeration systems and selective withdrawal offer potential solutions. Catchment management is vital, and investing in water quality management is economically prudent. A multifaceted approach is essential for sustainable hydropower. Read more

Erosion and sedimentation – why is it so important?
Managing sedimentation in hydropower projects is crucial due to its impact on efficiency and longevity. Sediment accumulation reduces reservoir capacity, impairs dam functionality, and affects energy production. Innovative strategies involving engineering and environmental science, along with stakeholder engagement, are essential for sustainable solutions that balance operational, economic, and environmental considerations.

Ecological connectivity
Hydropower projects, crucial for sustainable energy, pose significant challenges for fish migration. Alterations such as dams and flow changes obstruct migratory paths, impacting species like salmon and sturgeon. Turbines also pose a threat. Innovative solutions and rigorous environmental assessments, alongside comprehensive studies and regulatory frameworks, are vital for addressing this critical environmental challenge. Read more
