| Abstract/Description or Keywords | Examining patterns of bioturbation in larger rivers, we review the available data and observations that describe some of the conditions particular to Chinook bioturbation and dune bedform evolution in larger rivers. These rivers show large-scale perturbation of the bed, suggesting that sediment transport in the bioturbated reaches is strongly conditioned by spawning activity. Bed load flux rates are more difficult to quantify in these larger reaches. The morphologic imprint of the fish is not washed out as in the smaller systems, and analysis of sequential air photos suggests that the development and complexity of the bedforms is linked with the annual number of returning spawners. |
