Understanding Dredging

The Central Dredging Association – CEDA
Dredging is essential to the construction or maintenance of much of the infrastructure on which our economic prosperity and social well-being depend. It is also an important tool to restore and enhance the natural environment. It is an activity of which the wider public is largely unaware, but it is a field within which research has led to enormous developments in recent years. Against this background there is a need for a forum for the exchange of quality information on all aspects of dredging. Set up in 1978, the Central Dredging Association – CEDA - an international, independent professional society,... (read more)

CEDA Dredging Days 2011

Dredging is no longer a stand-alone exercise, but is rather becoming part of a broader, more integrated project realisation process. We are no longer in the era of "Dredging and nothing but dredging", we are in the century of "Dredging and beyond". The CEDA Dredging Days 2011, to be held on 10th and 11th November 2011 in Rotterdam, The Netherlands, will focus on two main areas where this integrated dredging approach is emerging. Subjects are Dredging and rock dumping for the offshore oil and gas industry and deep-sea mining; and Building with nature for soft and hard dredging solutions (coastal... (read more)

Dredging Point-cloud Software

Charting underwater structures, soils and project progression using GPS, sonar, single and multibeam systems produces a huge amount of data that needs to be analysed. Vast project areas can be analysed with the Point Cloud package by Pythagoras that includes user-friendly drawing, calculation and design tools and 3D visualisation of large point-cloud files and vector data. Datasets coming from total stations, GPS instruments, laser scanners, mobile mappers, UAV and drones, single and multibeam systems and other CAD and GIS software packages can be handled and processed. Calculating volumes, contour lines, cross sections, profiles, terrain models and exporting machine control datasets... (read more)

Environmental Aspects of Dredging

During a two-day Seminar, to be held on 10th and 11th March 2011 in Delft (The Netherlands), dredging experts and professionals present invaluable information on the interface of dredging and the environment. In addition, participants are challenged through case studies to apply this knowledge in order to get an understanding of the scope and significance of the environmental aspects of dredging projects, the management of dredged material, and effects of environmental guidelines. Dredging is a necessary activity in society's development. Under the right circumstances dredging is also an indispensable tool for remedying past environmental interferences. By its very nature, however,... (read more)
