Manage dams for sediment flow

Manage dams for sediment flow02. Sediment flow quantity improvement

General description

Expected effect of measure on (including literature citations):

  • HYMO (general and specified per HYMO element)
  • physico � chemical parameters
  • Biota (general and specified per Biological quality elements)

Temporal and spatial response

Pressures that can be addressed by this measure

Cost-efficiency

Direct sediment transfer cost should be about the same than suction dredging. However, the major cost share is not the suction work, but dewatering and deposition of the "surplus" sediment which often makes up 80 % of overall cost. On a global view, also from pure cost perspective sediment flow/transfer is much more efficient than sediment removal.
