Summary

This child data release includes fused topo-bathymetric digital elevation models of the Merced and Tuolumne Rivers in California used to support research on anadromous salmonids. The purpose of this study was to calculate the capacity for reintroduction of salmonids above impassable barriers. Airborne, near-infrared (NIR) LiDAR and hyperspectral imagery were acquired simultaneously in September 2014 from a Cessna Caravan, with the LiDAR data used to map topography of dry land and the imagery used to map water depth in the wetted channel. Topo-bathymetric DEMs of channels and floodplains with 1-m resolution were constructed for the study reaches by using remotely sensed hyperspectral image data to estimate water depths within the below-water [...]

Purpose

The purpose of this study was to estimate capacity for reintroduction in two iconic San Joaquin tributaries, the Merced and Tuolumne river systems. Currently there are no anadromous salmonids in either system due to large impassable dams. The goal of this investigation was to create a practical workflow that can be used to estimate this dynamic capacity at fine spatial and temporal resolution over a broad extent and extended time period, and use it to see what can be learned about capacity for reintroduction of Spring-run Chinook salmon and Steelhead in the our two river systems of interest. Information on channel and floodplain topography was used as input to hydraulic models that quantified water depths and flow velocities, two important aspects of habitat quality for these species.
