EHi -- Coastal_River_Lake

Coastal, River and Lake Processes When working in challenging coastal and riverine environments, engineers and scientists rely on accurate field data for project design, model calibration, and impact assessments, and ultimately for ensuring project reliability, function, and cost effectiveness. The staff at EHI have measured coastal processes around the world for more than 30 years using state-of-the-art techniques, providing our clients with accurate and reliable data.

Current and wave studies Information about currents and waves is often essential to projects being conducted in coastal, river and lake environments, including engineering projects (such as bridge construction) and environmental projects (such as shoreline change modeling). Specialized equipment is used to collect various data about marine conditions, which EHI staff will process, analyze and report upon. The exact nature and form of the study will depend on the specific requirements of the project. Return to top Return to services menu on home page
Discharge measurements Measurements of discharge (the volume and flow of water) yield information about the present condition and potential changes in waterways. This type of information can be invaluable in forecasting future effects, for instance, in assessing the potential for river flooding. Discharge measurements can be collected by using current meters from moving boats. Return to top Return to services menu on home page
Coastal processes and circulation studies Coastal processes impact the physical characteristics and well-being of our coastlines. Factors such as wind, current, tides and water fluctuations all contribute to a changing coastal environment, and an understanding of their effects helps predict and prepare for the future. Circulation studies show the distribution of sediments and help predict the likely location of concentrations over time. Through the expert deployment of specialized instrumentation, and by drawing on years of experience in this field, EHI scientists conduct start-to-finish studies that enhance knowledge and understanding of coastal environments.

Sediment transport The movement and settlement of sediment is an important factor in maintaining and optimizing use of waterways. EHI uses tracer studies to track sediment and report on its source and movement over different time periods. These types of studies are frequently commissioned by agencies responsible for waterway preservation and by engineering companies involved in the construction and maintenance of harbors and other structures. EHI has formed a strategic alliance with Environmental Tracing Systems, Ltd (ETS) to provide sediment and particle tracing services for the dredging, marine and environmental industries in the US.

Water quality monitoring and assessment Monitoring water properties in a defined area generates information about circulation and any associated sediment and bacterial problems. EHI has the expertise to determine the best combination of measurement techniques according to the water depth and environmental characteristics. These might include the release and tracking of dye and use of current meters. Return to top Return to services menu on home page
