New Environmental Monitoring Guidance for Dredging

Developers and regulators often require monitoring of the marine environment, to assess potential changes and impacts during construction projects.

More monitoring, however, is not necessarily better monitoring, and dredging experts from HR Wallingford have helped to produce new guidance on why and how environmental monitoring should be carried out.

Environmental Monitoring Procedures is a new Information Paper published by the Central Dredging Association (CEDA). It covers the different types of monitoring needed during the different stages of a dredging project, and includes a series of case studies which illustrate monitoring methods and uses.

The case studies represent various types of monitoring including: baseline monitoring, surveillance monitoring and compliance monitoring.

The examples are used to illustrate the relevance of adapting the monitoring program as the understanding of the system, and its response to pressures, changes. It also illustrates how the dredging may be adapted during the project period as a result of knowledge obtained by monitoring.
