These coarse materials can also find a place in Habitat creation or enhancement works, normally providing protection for vulnerable sites or areas for nesting birds or shingle flora. • Medium and Fine Sands - Finer grain materials are less suitable for use in structural reclamation, though if it is well contained there are uses as bulk fill or reclamation remote from quay structures. Although not employed so much in the UK, marine sourced sands are used extensively in Europe in a wide range of construction projects.
It was noted that there was a lack of consistency between local and area offices of the Environment Agency regulation staff, which was exacerbated by high staff turn over, problems with fragmented assessment and individual interpretation varying from officer to officer (Apitz et al, 2002). Potential Impacts The primary impact on the navigation industry will be an increase in costs for dredging projects. This in turn will cause navigational bodies to restrict the level of dredging to an absolute minimum and increase use of hydrodynamic methods.
1 bar) and keeping a small stand-off distance are key factors in minimising turbidity. The optimum stand-off distance, which depends upon the settled sediments' particle size distribution and permeability, is often determined through practical experience. The properties of the induced fluid mud layer depend on a large number of factors, but of prime importance are the particle size and viscosity of the sediment. Figure 2. The Material Exchange Processes HESK 41 The density current thus formed flows under the combined effects of gravitational, hydrostatic, current and friction forces.
