From 1956 to 2005, bathymetric surveys of South San Francisco Bay were compared to study sediment deposition and erosion. The analysis identified an erosional period from 1956 to 1983 and a depositional period from 1983 to 2005, with net changes varying by subregion. The dataset was summarized by the USGS.
Use Cases
- Model sediment regime shifts based on the identified erosional and depositional periods
- Analyze bathymetric change rates based on comparisons of surveys from 1956, 1983, and 2005
- Study subregional sediment behavior based on depth, morphology, and location classifications
- Investigate sediment supply changes based on patterns consistent with increased supply from Central Bay
Strengths
- Analysis spans a 49-year period from 1956 to 2005
- Compares three distinct bathymetric surveys from 1956, 1983, and 2005
- Identifies subregional patterns based on depth, morphology, and location
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
