Spatial Environmental Assessment Toolkit (SEAT) Plugin in QGIS
Contents
Introduction
The SEAT incorporates device specific parameters, site-specific hydrodynamic conditions, and local receptor information to assess the potential for environmental change within a system. Results from a successful SEAT application informs developers and regulators on the risk of environmental change associated with deploying a device or array in a site of interest. There are four modules available that assess different physical aspects of the impact of instruments on environmental conditions:
- Shear Stress Module: Analysis of spatial change in bed mobility
- Velocity Module: Analysis of spatial change in larval motility
- Acoustics Module: Analysis of acoustic propagation and thresholds
- Power Module: Analysis of power generated by WEC/CEC array
For this tutorial we will be using the Shear Stress Module on a coastal region of interest in Canada. This region is the Cow Bay/Eastern Passage area, south of Dartmouth.
