Bathymetric Mapping of California Reservoirs

Our surveyors have been active performing cutting-edge bathymetric mapping to investigate seafloor conditions and capacities of several California reservoirs. Utilizing our Multibeam Echosounder (MBES) and integrated mobile LiDAR system, McLaren conducted highly-detailed 3D scans above and below the water. The MBES emits sound waves in a fan shape beneath the boat’s hull using beamforming to extract directional information from the returning soundwaves. Several transducers allow for a large swath of area to be surveyed from a single ping, making the hydrographic survey fast and more accurate.

Simultaneously, the LiDAR technology utilizes remote sensing in the form of a pulsed laser to measure ranges to complete the full 3D model of each reservoir. This bathymetric mapping method for acquiring the data sources increases the accuracy of the water volume capacity calculations while also identifying potential erosion or sediment deposit related issues.
