​Establishing water depth, lake and river bottom profiles, features and shallow stratigraphy utilizing GPR techniques. Invaluable information for calculating river flow, water volume and informing lake bottom engineering design.

The bathymetry of fresh water lakes and rivers are typically measured by specific hydrographic equipment mounted to a vessel. GPR is no different, however often goes under utilized. The convenient form factor of GPR units, integration with mapping grade GPS and the ability to operate even if the water body is frozen, makes GPR ideal for this application.

Bathymetric data is essential for many disciplines, most commonly for scientific investigation, environmental monitoring and engineering works.

Dredging for example, requires periodic monitoring of sediment buildup and mobility to establish planning and execution of sediment removal. Understanding the deposition and/or removal of sediment material in times of high flow (i.e. flood events) can give insight into how rivers and lakes are evolving around us.

Radar travels much better in ice than in liquid water, a bonus for us in the great white north is that for once, throughout the winter months, the weather is on our side – improving signal transmission and therefore allowing us to survey deeper and with more clarity!

The same application applies for mapping the ice thickness itself, on roads, lakes, rivers, ponds, etc…
