Abstract

The acute and long-term effect on Chinook salmon during flushing events and natural flood events is estimated using the severity index and habitat suitability index at different locations after the events. Suspended sediment concentration at different locations after flushing events are used for determining the acute effects using severity index whereas, changes in bed composition, depth of water column, and velocity are used to estimate the suitability of the habitat of chinook salmon. Both flushing and natural flood scenarios are recreated using Delft 3D models in the Sandy River downstream of Marmot Dam (removed in 2007).

Additional Metadata

Name	Value
River Model	The river model consists of 4, Delft 3D model files for 3 flushing scenarios and one natural flood scenario.
Reservoir Model	The reservoir model provides 3 Delft 3D model files for flushing at 20%, 50%, and 80% of peak flow and also an excel file showing the results from these models which are used as an upstream boundary condition for the river model.
Habitat Suitability	This folder consists of 2 excel files as an example of how the severity and habitat suitability index was computed from the results obtained from the river model.
