What is a Bathymetric Survey?

1. What is a Bathymetric Survey?

2. Bathymetric is the study of the floor of a waterbody, which includes mapping of features on charts to offer details on water depth. These charts are usually made to help navigation and inform dredging activities. For instance, during maintenance of navigational channels. It is used as an echo sounder attached to the survey board. They also analyze and define the tides, surroundings, currents, and shorelines to make a better model of the area features overall. Using modern Acoustic Depth – surrounding instruments, the bathymetry survey of the river is done. After the field–data acquisition process is done, post-processing and use of data are needed to glean physically relevant details.

3. Types of Bathymetric Surveys Harbour and port surveys Wreckage surveys General Bathymetric survey Passage survey Coastal survey

4. 1) General Bathymetric survey This refers to studies of the water depth, determine of coastlines, mean sea level, and bathymetric plots. These are the most common ones and have applications in geological and science studies.

5. 2) Harbour and port surveys These are performed to find out the right locations to build these structures. Mostly undertaken by the national government, they find the best possible places that don’t have draft restrictions on vessels.

6. 3) Passage survey These are used to analyze the conditions of inland waterways, with the focus of turning them into passages for ships to go through. This is done to increase productivity and trade and the survey looks at analyzing mean draft, a restriction that needs to be imposed on the size of the vessels and the passage width.

7. 4) Coastal survey 5) Wreckage surveys This is done to analyze the coastline of a country and to document the flora and fauna. A Coastal bathymetric surveys in UAE is taken within the maritime boundaries of the country extending up to a specific mile beyond the coast. They also help in studying possible land reclamation projects. These are done to study the wreckage position. It can be done as a part of an investigative effort to analyze the probable case of the vessel sink. This can offer insight into the possible reasons for structural damage and flooding. During these operations, it is essential to make sure that no damage happens to both the surrounding and vessel areas.

8. The bathymetric survey includes techniques to offer single and multibeam, side scan, and sub-bottom survey services in the various marine environment. Services offered include real-time kinematic positioning accurate to within 2 cm, with heave compensation and real water level. Service also includes high-resolution single beam acoustic data for ponds, rivers, lakes, and coastal environments. This profiling of acoustic sub-bottom will help you find sediment distribution, the accumulation rate of rovers, volume, thickness reservoirs, and coastal environment.

9. A bathymetric survey service will provide you with the analysis of depth points and the velocity map of the river. It also provides a bathymetry map of the river bed and changes in the river beds over various surveys. Contact Falcon Survey Me, if you are looking for a seabed mapping with advanced technologies.
