WP6 – INTERACTIONS WITH STRUCTURES

Sediment management in diverse Alpine torrential watersheds and river basins must be based on a detailed analysis of the interactions between existing and planned man-made structures (i.e. torrent control works, hydropower plants, river restoration schemes) and sediment dynamics including large wood as an important habitat element. WP6 is dedicated to these interactions and will provide several guidelines to policy development in the field of integrated sediment management.

Actions

• Assessment of mutual interactions between control structures, torrential and river sediments, and large wood.
• Evaluation of the effects of hydropower dams on sediment continuity for design and planning purposes.
• Evaluation of river hydro-morphological alterations due to longitudinal sediment- continuity disruption and performance analysis of river restoration measures.
• Performance analysis and definition of optimal planning and design of torrent control works to reduce their impact on longitudinal sediment continuity.

Expected outputs

• Improved concepts of responses of torrent/river control structures to floods and debris flow impacts (including wood).
• Guidelines for planning/designing of efficient torrent control structures with low impact on sediment continuity between upstream torrential headwaters and downstream river reaches.
• Guidelines for improved planning of hydropower plants aimed to improve the longitudinal sediment continuity between upstream torrential headwaters and downstream river reaches.
• Guidelines for planning and designing of effective flood protection systems, river training and restoration projects that have lower impact on sediment continuity.
