Why is it important?

Monitoring sediment load and distribution during dredging and material handling in aquatic environments is important for infrastructure companies and environmental authorities to ensure that the health of these coastal systems is not disturbed.

By utilizing the opportunities that satellites provide, it is possible to optimize the timing of field campaigns so that any and all seasonal variations are included in the sampling based on historical data, and at the same time get more accurate and cost-efficient information than traditional monitoring techniques. This reduces the risk of dredging bans and limits damage from dredging.

How does it work?

Sediment detection from satellite information reduces the risk and damage of dredging while providing more accurate and cost-efficient information than traditional monitoring techniques.

Many infrastructure companies and environmental authorities face difficult circumstances when undertaking coastal constructions, dredging activities and general management of coastal activities.

Traditional monitoring methods include costly field based approaches with associated risks for both personnel and equipment.

We can provide you with a web-based solution that provides information on the spatial distribution, in near real-time, which optimizes construction and production activities and reduces costs.

What you get!

A quick and cost-efficient way of monitoring suspended sediment in your coastal area

A baseline to establish the spatial extent of sediment distribution and load

A tool to separate the effect of marine construction from natural occurrences

Typical customers?

Coastal managers use it for identification of potential sedimentation problems, for environmental impact assessments, and for monitoring conditions during coastal constructions

Coastal construction companies use it to document the environmental impact, for optimal site identification and to identify baseline conditions

Dredging companies use it to estimate sediment movements. To document environmental impact of activities and to calibrate sediment movement models


This type of information can be delivered in near real time for regional studies (250 m – 1200 m resolution) and within a few days for detailed studies (0.6 m – 30 m resolution)

Historical analysis possible based on archived satellite data to establish baselines

Cost-effective compared to traditional monitoring methods (in-situ collection, buoy measurements etc.)

Provides information on spatial variation – not just a point measurement

Data available in a ready to use format – easy incorporation into existing GIS systems and databases
