Bay-Delta SCHISM Processed Bathymetry
Listed in California Open Data
These datasets include processed Digital Elevation Models as used in important SCHISM studies, in particular the Delta Conveyance Project and 10 year retrospective.
Description
The datasets closely follow version 4.2 of our bathymetric data set but with three modifications:
- The DCP mesh includes some sections that are based on version 4.1 of our bathymetric data. These are bundled and labeled separately.
- Removal of subgrid curvature arifacts with the algorithm of Malladi and Sethian
- Inclusion of design surfaces for Lindsey Slough, Yolo Flyway Farms, Decker Island and Tule Red restoration areas.
- Synthetic extensions of the upstream reaches of the Sacramento and Mokelumne Rivers meant to prevent tidal reflection under extreme sea level rise. An extended lidar surface (not synthetic) is provided for the same purpose on Yolo Bypass
