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 fielddata acquisition process
is done, post-processing and use of data are
needed to glean physically relevant details.

Types of Bathymetric Surveys

Harbour and port surveys
Wreckage surveys
General Bathymetric survey
Passage survey
Coastal survey

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.

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 dont have draft
restrictions on vessels.

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.

4) Coastal survey
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.

5) Wreckage surveys
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.

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.

• 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.
