What is the common purpose of Hydrographic Analysis?

Hydrographic Analysis:

Hydrography is the study of how water moves through the world. Hydrography is the branch of science that studies and describes the physical features of the parts of the Earth that can be accessed by water. Hydrographic surveyors look at these bodies of water to see what the “floor” looks like, then report back to the government.

NOAA’s Office of Coast Survey does hydrographic surveys to determine how deep and flat the bottom of water bodies is. Data is used to make changes to nautical charts and make hydrographic models. This information is essential to navigating the ocean and our country’s waterways.

Hydrographic Analysis or surveys are also used in NOAA’s Integrated Ocean and Coast Mapping program, which helps with many things, like building seafloor structures, laying pipelines and cables, dredging, anchoring, and understanding fish habitats.

A hydrographic survey is:

Hydrographic Surveying is a branch of surveying that deals with anything that is still or moving water, like a lake, harbor, stream, or river. 

The Goals of hydrographic surveying:

For one or more of the following, hydrographic surveying is done.

  • Measurement of tides for sea coast work, such as building sea defense works, harbors, and so on, to get leveling data and to cut down on the amount of sounding.
  • Soundings are used to find out how deep the bed is.
  • To help you get around.
  • Or find where rocks, sand bars, and navigation light.
  • Because of where under waterworks are, the volume of underwater excavation, and other things like that.
  • As part of irrigation and land drainage schemes.
  • It’s number three: figuring out which way the current is going.
  • It is where any pipe or channel sends wastewater outfalls.
  • Measure water quantity and flow in connection with water schemes, power schemes, and flood control. 

Why need hydrographic surveys – what are the uses of hydrographic surveys:

  1. There has been a lot of growth in offshore engineering and the shipping industry.
  2. A drilling rig, used to find resources in the deep sea like oil and gas, looks for them up to 125 miles offshore.
  3. Dredged material is used to build offshore islands because it can be brought from somewhere else and dumped there to support marine structures.
  4. A harbor depth of at least 80 feet is needed to fit bigger ships and tankers.
  5. Containerization has become an efficient and popular way to move goods.
  6. It ranges from big pleasure cruise ships to small sail bonds.
  7. Then, cruise ships go to small sail bonds. These surveys are done to a group and show information about oceans, lakes, or harbors that they found. 

Final Words…!!!

Determine the shorelines, soundings (measurement of depth below water level), characteristics of bottoms, areas subjected to scouring and sedimentation, depth available for navigation.
