Advanced coastal mapping to support hydrodynamic modelling (Lidar)

Principal Investigator:

Dr. Tim Webster and Dr. Wayne St-Amour, NSCC Applied Research

Start Date:      April 2016

End Date:       April 2018

This project will use an innovative airborne Lidar system to collect surface and shallow submarine topographic data. The data will then be used in a hydrodynamic model to predict water movement (and by extension nearshore oil dispersion) adjacent to a complex marine tidal inlet system. The ability of the Lidar sensor and camera to map near shore topography, bathymetry, and sensitive habitats will be evaluated. The results will then be inputted into HD models to provide enhanced oil spill cleanup preparedness tools. Further, navigable pathways will be mapped within a dynamic nearshore system to demonstrate how the data can aid in the planning of cleanup efforts that could otherwise be dangerous using traditional navigation methods. Data regarding the critical distance, magnitude, and timing of impacts from potential oil spills will provide better information to responders to help guide restoration efforts, reduce costs and mitigate health and safety risks. Future phases of the project based on results from this project, may further refine model result through the use of dye tests and additional detailed current measurements.
