Evaluating the effectiveness of rehabilitation actions in creating fish habitat in the Trinity River
A simulation model of the Trinity River was first developed that models the impacts of different habitat creation actions and flow regimes upon future changes to the habitat. We then evaluate several experimental designs to determine which designs are most likely to detect a difference in habitat creation resulting from different mechanical rehabilitation actions. We model the formation of berms using transition state matrices derived from expert opinions. The model creates different transition matrices for various rehabilitation actions, flow volumes and dependence on upstream conditions.
Finally, the performance of alternative designs under different model conditions is compared and presented.
This model will be useful in helping the Trinity River Recovery Plan assess which actions will lead to the creating and maintenance of future fry habitat.
This type of interdisciplinary work is a hallmark of our program in Applied Statistics at Simon Fraser University. For more information, please contact Darcy Pickard (firstname.lastname@example.org) or her supervisor Carl Schwarz (email@example.com), Department of Statistics and Actuarial Science.
