Sea Level Rise CalFloD-3D
This data provides predicted inundation location and depth for the San Francisco Bay area, the Sacramento-San Joaquin River Delta and California coast resulting during likely future storm events at different sea level rise scenarios. This research is unique and innovative in its dynamic spatial detail and the fact that it incorporates real, time series water level data from past (near 100 year) storm events to capture the dynamic effect of storm surges in modeling inundation using 3Di, a three dimensional hydrodynamic model along with high resolution earth surface models.
The San Francisco Bay and Sacramento-San Joaquin Delta are modeled at spatial resolutions ranging from 3m x 3m to 12m x 12m tiles. Due to the large extent of the California coast, coastal areas are modeled at a coarser resolution of 50m x 50m tiles and do not include surface object elevations. Details are described in Radke et al., 2016.
Spatial Resolution and Extent
Cal-Adapt provides inundation depth mosaics derived from the original tiles for the San Francisco Bay area, the Sacramento-San Joaquin Delta and the entire California coast. The mosaics were produced using the following steps:
- Resampling the inundation depth layer for each tile to 3m x 3m spatial resolution for the San Francisco Bay and Sacramento-San Joaquin Delta. The coastal data retains the original resolution of 50m x 50m.
- Rounding the inundation depth values (in meters) to 3 decimal places.
- Mosaics are assembled as maximum of source layers.
Sea Level Rise Scenarios
Data is available for inundation based on a real near 100-year storm event coupled with 0.0, 0.5, 1.0, and 1.41 meters of sea level rise.
