Total Hydrographic were approached with a brief to map over 35km of Inland River Waterways. The council were after survey data that could help provide them with a clear understanding of the bathymetry and the location of hazards and debris that could be a problem for recreational boating.

The objectives of the survey was to provide full bathymetric survey and provide a volume assessment for the renourishment site to meet the 3D design model. The data that we provided allowed the client to make an informed decision, based on quantitative and visual data presentation, as to the best mode of practice for dredging and renourishment operations.

In a drought prone country like Australia, where millions of people rely on the country’s many reservoirs for a safe and dependable water supply – efficient, forward thinking and strategically planned reservoir management is crucial. The risk involved in reservoir management can be mitigated with quick access to relevant and accurate data.

This image is an extract from a hazard clearance survey of a lake. The client needed to know that there was a minimum clearance depth of water available at particular water levels. There were many hazards on the lake bed, however the survey revealed that they were all deeper than the client’s required minimum depth.

Multibeam survey data can be presented in many ways. 3D contours are often a great way of presenting what is happening on the seabed. This Yacht Club survey not only reveals the depths but also the old pier alignment and extensive aquatic vegetation in the southern shallows.
