Dragflow, environmental-proof technologies. Beyond business for love of the Earth.
Dragflow chooses to soften the environmental impact with advanced technologies for dredging optimization and naturalistic protection. High performances imply a specific attention towards ecosystems where the operations are carried, since they often are fragile and easy to jeopardize. That’s why Dragflow conceived technical solutions like the anti-turbidity bell: designed to preserve ...

Control of dredging works in the Danube River - Austria - Case study
The Austrian waterway management has introduced an automatic system to monitor a series of barges, which calculates the dredged material as a basis for handling invoices of the dredging companies. Before converting to a remote data transmission option, all calculations were entered manually. The datalogger saves the cost for hand-writing documentation of the dredging works by external staff and ...

Sediment spill monitoring from dredging, using the SediMeter
Strategies for sediment spill monitoring and siltation measurements. The SediMeter allows a gradual increase in the equipment investment as conditions merit, from a single stand-alone logger, to a real-time monitoring network in which all previously purchased equipment can be included. Sediment spill causing siltation gives rise to two separate environmental problems: A suspended sediment plume ...

Performance of a pilot showcase of different wetland systems in an urban setting in Singapore
The Alexandra Wetlands, part of PUB's Active, Beautiful, Clean Waters (ABC Waters) Programme, showcase a surface flow wetland, an aquatic pond and a sub-surface flow wetland on a 200 m deck built over an urban drainage canal. Water from the canal is pumped to a sedimentation basin, before flowing in parallel to the three wetlands. Water quality monitoring was carried out monthly from ...

Confined disposal facilities: History and trends
ABSTRACT Confined disposal facilities with filter layers have been used for disposal of dredged sediments for decades. Recent assessment of the environmental risk of contaminants in sediments has resulted in the use of lined confined disposal facilities. A case history outlines a contaminated sediment disposal facility designed with geosynthetics. Trends indicate more stringent requirements for ...
