CEDA Dredging Days 2017

Sustainable Dredging - Continued Benefits


9-10 November 2017, Rotterdam, the Netherlands

Project initiation, planning and design

  • Sustainability and added value
  • Methods to develop sustainability in design
  • Sustainability consideration at earliest stage of project development
  • Understanding and using typical features of project region
  • Stakeholder engagement
  • Different perspectives on infrastructure development
  • Handling uncertainties by risk- (and opportunity) based design
  • Creative solutions by multi disciplinary collaboration

Environmental and social assessment, prediction, modelling and monitoring

  • Pre-project assessment and prediction of project-attributed effects
  • Hydrodynamic modelling of dredging works against background situation
  • Monitoring of near-field and far-field effects
  • Implementation of adaptive management for mitigation purposes
  • Sustainability as performance criterion in contracts
  • Education and training of local workforce

 Sustainable working method and equipment

  • Turbidity: reduction, source term prediction, mitigation and modelling
  • Energy efficient equipment and working methods
  • Sustainable extraction and placement methods
  • CO2 reduction measures

Sediment management

  • The relation between capital dredging projects and the natural sediment budget
  • Maintenance dredging as a tool for sediment balance in estuaries
  • Reuse of dredged sediments
  • New evolutions in beach nourishment for eroding coasts
  • Artificial islands influencing the sediment balance
  • The impact of climate change on sediment management

Inland dredging

  • Challenges of dredging and maintaining small inland waterways
  • Hydrodynamic dredging of slow flowing canalised inland waterways
  • Challenges of dredging and maintaining large inland waterways for uninterrupted service to the economy, environment and society
  • Dredging of lakes and reservoirs to improve/maintain hydromorphology and water quality
  • Hydrographic survey techniques for shallow waterways
  • Advancements in sediment analysis to meet requirements of changing legislation
  • Managing the conflicting demands of the users of inland waterways
  • Specialist plant & equipment (and techniques) for dredging and treating sediments from small waterways
  • Sediment management strategies for large waterways
