Our engineers and geologists specialize in dam and levee safety evaluation and design. We evaluate seepage, stability, and seismic behavior of embankment dams and levees to evaluate potential deficiencies and develop efficient retrofit designs to mitigate deficiencies. Our engineers are highly experienced in using powerful analytical tools to model complex behavior, including liquefaction, extreme ground shaking, and large permanent deformations. We utilize FLAC for modeling liquefaction and highly nonlinear behavior, and other finite element programs, such as QUAD4, for more simplified modeling. We have also developed and implemented pre- and post-processing modules for QUAD4 and FLAC to allow for efficient randomization of material properties and ground motion inputs. We have used these tools for probabilistic analyses of slope instability for use in quantitative risk analyses.
We perform safety inspections and FERC 5-year Part 12D safety inspections at hydroelectric facilities throughout California. We are experienced at facilitating Potential Failure Modes Analysis (PFMA) workshops and developing detailed reports to support a robust dam safety program and to meet FERC requirements. We execute risk analyses and assessments so our clients can make risk-informed safety decisions to mitigate potential risks to public health and safety, physical property, and the environment.
