Ecology Landscape Recreation SEINE- SCHELDT Definition of River Restoration

“All measures to restore or reinforce the structure and processes which contribute to the dynamic balance in the river ecosystem”

•River ecosystem = river bed + meanders + embankments •Dynamic balance: a river is in constant evolution • Erosion vs. sedimentation • Flooding vs. droughts HISTORY OF THE LYS

• Deepening of the Lys • New lock Hoge brug • New weir • Restoration of migratory routes for fish • Heightening of Kuurnebrug upstream (*) • New Hoge Brug downstream • New waiting and mooring places • Construction of (ecological) embankments

(*) not part of D&B

Kuurnebrug SEINE- SCHELDT IN HARELBEKE (2/3)

• Dredging + protection against erosion Site Geldof • Straightening of waterway downstream Hoge Brug • New urban quay • New industrial quay Geldof • Realisation of intake at Banmolens • Renovation of hydraulic turbine Banmolens (*) • Continuous service road on left bank (+ bridge over intake) • Road works on right bank

(*) not part of D&B Banmolens SEINE- SCHELDT IN HARELBEKE (3/3)

• Spatial planning (without realisation): • Passage of the Lys at the new lock & weir • Insertion of Marina () • Impact assessment on Urban new urban quarter on left bank development • Overall spatial valorisation of the surroundings (o.o. Bloemmolens)

Bloemmolens HARELBEKE: MAIN PROJECT ZONE EXISTING INFRASTRUCTURE (1/3)

• Banmolens

• Industrial heritage • Reconversion project • Lofts • Hydraulic turbine • Intake needed! • Spatial cohesion • Fish migration? EXISTING INFRASTRUCTURE (2/3)

• Bloemmolens

• Industrial site until summer ‘09 • Acquisition by W&Z to safeguard space for future lock and weir • Possibility to transform into lofts? EXISTING INFRASTRUCTURE (3/3)

• Straightening the curve • Urban quay widening • Industrial quay Geldof

STRAIGHTENING THE CURVE

Max. 42.75m Min. 35m

Ca. 8m INDUSTRIAL QUAY GELDOF

• Continuity of Geldofs activities • Straightening the curve implies building a new quay wall downstream • Acquisition planned nearby

EXPLOITATION & MAINTENANCE REQUIREMENTS

• Life Cycle Management “keep the Whole Life Cycle Cost to a minimum” • Avoid calamities • Renewable energy sources • Accessibility of the (construction) site CONCLUSION OF PRELIMINARY STUDY

• The construction of a new lock and weir at one of the main challenges Harelbeke is for the international Seine-Scheldt project

many conflicting goals • There are that need to be reconciled

• An integrated project, by means of a Design & Build procedure is launched, based on two variants OVERVIEW
