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.

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)

Dredging Roadmap, Protocols, Facts

Facts About International Maritime Conventions is a roadmap through the complicated regulations governing dredging and explains in brief such concepts as the ‘reverse list', the precautionary approach and the adaptive approach, as well as the London Protocol and the OSPAR and the Dredged Material Assessment Framework (DMAF).   International regulations that are followed by all shipping nations have long been seen as the best way to improve sea-going safety.
