ENVIRONMENTAL RISK AND RELIABILITY FOR SUSTAINABLE DREDGING

Dredging work and placement leads to changes to the environment. Environmental impact assessment has been employed to address these changes. Risk assessment which rarely covers large part of uncertainty associated with dredging work is captured in EIA. EIA focus on fixed and inflexible standards which have led to post dredging failures. This makes it necessary to do critical and dependability scientific risk analysis that quantitatively determine whether the changes are serious or irreversible.

This paper discuss the new internationally recognized philosophy of risk analysis or formal and system risk based design that provide opportunity to focus on real concern of the dredging project. The paper will discuss case study of failed project based on conventional EIA and best practice performance of systemic risk base design approach.
