摘要

The California Department of Water Resources (DWR) Urban Levee Geotechnical Evaluations (ULE) and Non-Urban Levee Evaluations (NULE) Programs are evaluating approximately 1,950 miles of urban and non-urban levees in California's Central Valley. The amount of historical data associated with these levees (historical performance, design, maintenance) is staggering.rnSimilarly, the collection of program-generated site-specific data like subsurface exploration logs, laboratory test results, light detection and ranging (LiDAR) survey data, bathymetric data, and helicopter-borne electromagnetic (HEM) survey data is voluminous and will continue to grow in size as the levee evaluations continue. Collected historical and program-generated data needed to be cataloged and formatted in such a way that data are readily available to geotechnical evaluation teams and program stakeholders. This paper discusses how existing and program-generated data are handled in the Levee Evaluations Database, an integrated documents database. It also discuses how the database works in association with geographical information systems (GTS) to efficiently respond to ULE and NULE Program needs.rnULE and NULE Program teams developed the Levee Evaluations Database to identify and catalog collected historical and site investigation information. This information is also compiled in a GIS database. Database integration allows GIS specialists to create data layers of site-specific information into specialized maps that can be overlaid with other relevant levee information. Resulting maps can show geotechnical conditions in a specific levee reach and help analysis teams assess existing conditions, prepare analysis cross sections and correlate analysis results with historical performance information.rnThe combined Levee Evaluations and GIS databases also facilitate retrieval of collected information. These combined databases helped ULE and NULE teams catalog, manage and organize terabytes of information and knowledge. They also promote consistency and uniformity of available information, and improve communication across the levee evaluation teams. These databases have already proven indispensable when generating levee profiles and the cross sections required for geotechnical evaluations and analysis.
