A survey ship with a specially developed silt profiler – designed and constructed in 2009 and owned by the Port of Rotterdam – follows a trailing suction hopper dredger at work to measure active and surface plumes. This was an integral part of the extensive monitoring programme at the Maasvlakte 2 expansion project in Rotterdam (see page 20).

The “soft” side of the closure of the sea wall at the Port of Rotterdam’s Maasvlakte 2 extension project, where sand was rainbowed onto the outer contour, was initiated in July 2012. This land reclamation increases the area of the Port of Rotterdam by 20% and makes the Netherlands 2,000 hectares larger. With a coastline 3.5 km further into the sea, it required extensive monitoring before, during and after construction (see page 16).

The newly expanded Falmouth Cruise Ship Terminal in Trelawny, Jamaica. To realise the dredging and reclamation works required for this economically important port project, an extensive environmental mitigation plan was implemented to preserve coral and other marine life by harvesting coral colonies, transporting and reattaching them at suitable locations and monitoring their health (see page 15).

The reclamation areas on the Danish island Lolland (dashed white lines) are an essential part of the sustainable design for the proposed Fehmarnbelt Fixed Link connecting Scandinavia and continental Europe. The design ensures that the reclamation areas do not extend beyond the existing ferry harbour at Rødbyhavn and do not impact the protected area at Hyllekrog (see page 20).

New Caledonia's tropical lagoons and coral reefs are one of the three most extensive, highly diverse reef systems in the world. Shown here, a sampling of the multitude of exceptional coral and fish species found there. For the dredging works inNew Caledonia a detailed Environmental Management Plan (EMP) was prepared and its successful implementation proved that good environmental management, which uses both pro-active and re-active approaches, can prevent unnecessary consequences (see page 25).

TASS (Turbidity Assessment Software) has been developed to address a need recognised by the dredging industry that the quality of predictions of the effects of dredging for Environmental Impact Assessments must be improved. Shown here, the results of TASS models are being validated by the Survey vessel Corvus, conducting experiments in the plume of a trailing suction hopper dredger (see page 14).

In the foreground a small elevated platform for geotechnical sampling through a shallow rock seabed and in the background a landing craft for soils sampling in excess of 5 m water depth. conducting a detailed geotechnical site investigation is crucial to the execution of a successful project, therefore, dredging contractors and consultants need to be involved early on so as to avoid expensive “surprises” once work starts (see page 24).

Aerial view of the 6-acre (2.5 ha) processing facility and offices along the banks of the Fox River in northern Wisconsin where a major cleanup project, involving dredging, capping with coarse sand and separating clean sand and dewatering the fine sediments with membrane presses, is taking place in order to remove PCB contamination and restore the natural beauty of the river

The 4,200-km-long River Niger, one of the longest in Africa, meanders through several countries. Dredging and River Training Works on the lower 575 km in Nigeria will regulate the river’s depth there, making it usable for water-borne transport of goods and improving the social and economic lives of the people living along the river (see page 27).
