Larval Transport Analysis (Velocity)

This set of inputs evaluates the impact on larval motility given a single critical velocity receptor in a CSV file.

Input

At this point you should have already setup the input files and style files as detailed in Prepare Tutorial Files.

To run this demonstration, use the Load GUI Inputs button located at the bottom left of the SEAT GUI, navigate to DEMO/tanana_river/velocity_with_receptor.ini, and click OK to load the inputs. If you need detailed instructions on how to load inputs, please refer to the Save & Load Configuration section in the SEAT QGIS Plugin documention.

In brief, the model data consists of individual .nc files for each flow return period. The period within the .nc filename determines the probability of occurrence. There is a set of results for no device and a set of results for 9 devices in the river.

Note

Your paths will differ than the ones shown in the example below. If you get an error double check the paths making sure the files exist at the specified location.

Output

For this case the velocity with devices is compared to the velocity without devices and a difference (stressor) is calculated.
