One-line model description Simulates freshwater mussel populations' response to changes in suspended sediment
Extended model description This model simulates the interaction between suspended sediment, chlorophyll-a, and mussel population density. Discharge is the driver; it modulates suspended sediment and its interactions in the system. The model is suitable for simulating mussel densities at-a-site. It was originally developed to test the hypothesis that increased sediment loads in Minnesota Rivers are a plausible cause of observed mussel population declines. The model and results are described in detail in the following paper:

Describe processes represented by the model See the associated published paper:
Describe key physical parameters and equations See the associated published paper: and the readme file for parameter descriptions.
Describe length scale and resolution constraints Spatial scale is implicit; resolution is n/a.
Describe time scale and resolution constraints Model constructed for daily time steps, but can be altered with little effort.
Describe any numerical limitations and issues None known; the model requires very little computational expense.

Describe available calibration data sets See readme file and the associated published paper:

Calibration must be performed on a site-by-site basis; the provided data do not permit calibration for our sites, but we do include the calibrated parameters and explain our methods.

Do you have current or future plans for collaborating with other researchers? This was an effort by a team that no longer works together closely as a whole, although we collaborate in other arenas. As far as I know, there are no current plans to collaborate regarding this model, although it has been shared with various researchers for their projects.
Is there a manual available? No
