Even if you're familiar with different types of land surveying, you may not be familiar with the bathymetric. These types of surveys use various techniques to measure the depth of a body of water and note the underwater features. Here is more information on how and why these are conducted.
They Can Be Conducted With Several Methods
The most common land surveying technique used with this type of survey is the multi-beam method, which involves attaching an echo sounder to the bottom of a boat and sending out multiple signals across a large portion of the water. This technique is similar to the single-beam method, which only sends an alert to the area directly under the boat. In addition, Ecomapper autonomous underwater vehicles will be deployed to gather data where a ship cannot go.
Acoustic doppler current profilers will be deployed to measure streamflows. In addition, sub-bottom profilers will also be deployed to examine the sediment and rocks at the bottom of a body of water.
They Are Useful for Different Types of Research
As mentioned, a bathymetric survey gathers critical data about the contours and features of a body of water. That can be helpful when researching an area because it can offer insight into natural phenomena such as flooding. For example, it can see if there is any possibility of leakage or if flooding will only come from stormwater. It can also look at the stability of the body of water in the long term.
Furthermore, it can offer insight into water quality for drinking or habitation. For example, it can see if there has been any environmental impact or if the biology of the water is still pure.
Bathymetric surveys offer information about bodies of water. This type of survey is critical for understanding more about these aquatic environments.
