From: Effects of sediment flushing operations versus natural floods on Chinook salmon survival
Temporal variation of the percentage of river surface that is suitable for the different life stages of Chinook salmon after the start of (a) the natural flood event and (b) the flushing operation starting at 80% of the flood peak and, the percentage of area suitable for eggs according to water depth, flow velocity and fine sediment and composite Habitat Suitability (HSI) at different times after the start of (c) the natural flood event and (d) the flushing operation starting at 80% of the flood peak.
