What is the lake bathymeters?

BATHYMETRY measurement technique through Sonar Sounders has existed since the age of 30. Bathymetry is used to measure the depth of ocean floors and outline features of bed in other water bodies. The technique of lake bathymetry, as the name suggests, concerns the measuring of the depth of the bed over the body of the lake. The interpolation of Sonar values ​​can be built a three-dimensional (3-D) map of the lake flooring showing outlines and other features of the bed.

The water formation is equipped with a number of ridges, riverbed and outlines of general depth known as isobaths. Bathymetry is a study of these features of the bed, which is performed using echosoundes Monobeam or Multibeam. These echosunds make rays of sound or lights from recording to the bed of the water body. The water depth at this point is determined by the time needed for sound or light to return to the recording system. This technique is often referred to as Jakonar Pinging. By emitting and recording a range of beams arranged in a fan pattern, Multibeam Echosounders can record wider OBLast and therefore requires fewer passages. The arrangement of the beam fan also increases the accuracy of the mapping of very steep or vertical surfaces on the surface of the bed.

In terms of safety, the lake bathymetry can be used to provide instructions for surface navigation. Another use that focuses more on the application for fans is the study of the outline map to identify the best areas for fishing. These graphs are known as bathymetric charts. The first tool used to create bathymetric graphs was a pre -award -winning rope that was reduced on the side of the ship. This original technique proved to be inaccurate due to the effects of underwater rope streams outside the center and was also a very time -consuming task, with only one depth measurement.

Modern Bathhymmetry Systems Lakes are equipped with global positioning devices (GPSS) and height that enables PR modificationson the compensation of the role of the container on the surface. Global navigation satellite systems (GNSS) are also used in ocean bathymetry along with less satellite images. The lake bathymetry technique is less common than the ocean topography study and is mainly used for the safety of vessels, recreational activities and studying mineral and rock deposits on the lake bed.
