Papers are concerned with approaches for treating and detoxifying sediments and for isolating and stabilizing contaminated sediments by capping or in disposal facilities. Authors describe their experiences with monitored natural attenuation of sediments and with a wide variety of treatment technologies (e.g., physical, chemical, thermal, electrokinetic, enhanced biodegradation, phytoremediation) to remediate sediments and wetlands. Several papers focus on options for beneficial reuse of sediments and on containment/immobilization approaches. Book jacket.
"During the latter part of the 20th century it became clear that another approach should be found for handling contaminated dredged material. Up to then it was common practise to dispose dredged material at sea or use it to raise the land or as fertilizer on land. A new approach was to store contaminated dredged material in confined disposal facilities (CDFs). These CDFs are only meant for dredged material that is heavily contaminated and cannot be relocated into the water system or used for engineering or environmental purposes. Much effort was devoted to the design of CDFs and to the assessment and management of environmental risks. Despite the fact that stricter environmental pollution controls meant that sediments in rivers and harbours became less contaminated and options for use of dredged material became more available, there still is the need for more storage capacity for contaminated dredged material arising from certain capital, environmental remediation and sometimes maintenance dredging projects. It is especially difficult to decrease the influence of diffuse sources on contamination levels of sediments."--Introduction.
This report provides guidelines for the sustainable development of recreational navigation infrastructure (RNI). There are multiple potential benefits of recreational navigation infrastructure, but it is critical for sustainable development that these opportunities become actual benefits. This report provides guidelines for a design process and illustrates project features that can achieve this goal. It also outlines the benefits that sustainable RNI provide, as an economic engine with social and environmental benefits, in sustainable tourism, in large infrastructure projects, in urban waterfront projects, and as part of broad conservation strategies.
