Hydrodynamic Modeling
Wapato Reach
Yakima River
Study Objectives
- Estimate the hydraulic characteristics of the Wapato Reach over a range of flows, from 300 to 15,000 cfs
- Provide spatially explicit hydrodynamic layers (i.e., velocity and depth) to the USBR as input into a decision support system that will be used to determine suitable spawning and rearing habitat for salmonids
