Corps of Engineers’ dams are challenged to perform beyond their intended service life, with increased risk to people and property downstream. In particular, dams on limestone or other geologic materials susceptible to dissolution have critical needs for subsurface retrofit and repair. Historical information about foundation conditions is often in paper format only, and does not capture current conditions because of subsurface changes due to grouting, compaction, and dissolution. Corps Districts need digital tools to define, visualize, and model changing conditions of dam foundations and abutments. These tools are needed to identify areas at greatest risk and to plan and document the effects of foundation grouting and other remedial activities. |
