Project II.4.2: Anthropogenic changes
Project Title: II.4.2 Anthropogenic changes
Project Lead: Modeling Team
Project Description
Several human-imposed manipulations of the Columbia River coastal margin are simulated using modified versions of the standard river-to-shelf domain grid. The results are analyzed to characterize the impacts of the changes on Columbia River processes
Fit in program
This scenario directly addresses one of the CMOP grand challenges.
Outcomes
The following Columbia River alterations have been defined and incorporated into the simulation run, using db14 weeks 16 through 36 of 2004 as a baseline:
| Anthropogenic Change | Short descriptor |
| Dike Removal | The standard river-to-shelf grid with estuarine boundaries unprotected by dikes. |
| Grays River restoration | A specific scenario of restoration defined for the Grays River, a mid-estuary affluent with tidal influence. |
Several aspects of these simulations have been evaluated, including the physical characteristics of the plume, the maximum distances of salinity intrusion, and the relative availability of juvenile salmonid habitat (as defined by velocity, depth, temperature, and salinity).
