Types of Dredging Projects
Types of Dredging Projects

Dredging projects are often classified into three categories: capital, that is, for new infrastructure, maintenance, or remedial (environmental) projects.

Long-Term Effects of Maintenance Dredging on Turbidity
Long-Term Effects of Maintenance Dredging on Turbidity

Maintenance dredging is required in many estuaries worldwide to provide access to ports and inland waterways. A newly developed dredging module is able to capture the two fundamental processes necessary to model the long-term impacts of dredging on turbidity.

The Use of Engineered Sediments for Dyke Construction in the Flood Control Area of Vlassenbroek
The Use of Engineered Sediments for Dyke Construction in the Flood Control Area of Vlassenbroek

By preparing material from maintenance dredging with selected additives, a protective dyke was constructed from 100% reused sediments.

The Port of Lisbon, Portugal: Maintenance Dredging in a Sensitive Environmental System
The Port of Lisbon, Portugal: Maintenance Dredging in a Sensitive Environmental System

With dredging responsibility for 11 municipalities along the environmentally sensitive Tagus estuary, the Port Authority of Lisbon needed an integrated strategic dredging plan. After detailed studies, they got it.

Uncertainty Analysis of the Mud Infill Prediction of the Oklng Approach Channel
Uncertainty Analysis of the Mud Infill Prediction of the Oklng Approach Channel

To take well-founded financial decisions, help manage risks and reduce uncertainty, a model for calculating the probabilistic assessment of maintenance dredging volumes was developed using the Olokola LNG project near Lagos, Nigeria, as an example.

Depth-Utilization Analysis for Estimating Economic Activity Supported by Dredging
Depth-Utilization Analysis for Estimating Economic Activity Supported by Dredging

The 2009 IADC Award for the Best Paper by a younger author evaluates how to prioritize channel maintenance dredging to ensure the safety and economic viability of waterborne transportation.

Possibilities of Minimising Sedimentation in Harbours in a Brackish Tidal Environment
Possibilities of Minimising Sedimentation in Harbours in a Brackish Tidal Environment

By studying the different mechanisms of sediment movement, solutions were developed to reduce sedimentation in harbours, and thus reduce the need for maintenance dredging.
