ENVIROMUD and its associates provide sediment, water quality, and bathymetric monitoring and analysis to provide understanding of local sediment transport processes. Measurements provide ‘real data’ for assessment of marine civil engineering works and dredging. This data can be used together with numerical models to enable informed decisions for sediment management.
Terrestrial run-off results in storm-drain and watercourse discharges at the coast which can have a significant impact on the nearshore environment from sediment load, water clarity and chemical constituents. These may have adverse impacts such as water quality affecting marine life and bathing beach standards. ENVIROMUD has the expertise and experience both to carry out informed coastal environmental impact assessments and investigate appropriate mitigation measures.
Aquatic aggregate extraction and mineral mining are huge industries worldwide and are intrinsically involved with sedimentary systems. Our surveys and consultancy services provide essential data and advice for both optimising the processes of extraction and minimising any environmental impact in line with regulatory requirements.
ENVIROMUD can accurately assess the stability of cohesive sediment using SedErode, Shear Vane or CSM technologies, and with use of the AQUAMUD Scale (Such Salinger Peters Ltd, 2007). Determinations of erodibility and erosion potential can be applied to provide a ‘score’ from 1-10, indicative of the likelihood of erosion. This risk-based approach can be used to evaluate and predict movement of ‘harmful’ cohesive sediments and soils often containing pollutants, pathogens and organics (often sewage derivatives) from its’ source to a location downstream. Mitigation measures can then be investigated and prioritised to provide effective solutions preventing undesirable effects.
Assessment of the ‘health of the seabed’ relies upon sensitive investigation of habitat and benthic ecology. Correct management of a range of sensitive habitats is now seen as key to conservation effectiveness. A sound understanding of local seabed characteristics and sediment transport processes allows exploration of new ways of conserving and sustaining these important areas for the future.
Muddy sediment transport knowledge is important in fluvial settings, catchment run-off from fields, and drainage systems. Transfer of fine sediment and pollutants can adversely affect the water quality of downstream water bodies and is a real problem during flooding events. ENVIROMUD can measure and evaluate sedimentation problems and contaminant pathways in these scenarios.
