New report on wildfire evacuations for Paradise and Bolinas, CA

A new technical report is recently completed by the Soga Research Group highlighting the socio-technological challenges faced by California communities in wildfire evacuations. In this interdisciplinary effort, a team formed by researchers in wildfire simulations, communication process modeling, and traffic simulations, worked closely with community partners to identify and reconstruct realistic evacuation scenarios for the two case study areas in Bolinas and Paradise, CA. A… Read More »New report on wildfire evacuations for Paradise and Bolinas, CA

SRG researchers take on working platform design using DFOS

A team from the Soga Research Group led by Ph.D. candidate Peter Hubbard is working with a team from Malcolm Drilling led by Peter Faust to assess the performance of working platforms in San Francisco when subject to large loads from drilling rigs using distributed fiber optic sensors (DFOS). A working platform is a layer of material that is placed on top of the existing… Read More »SRG researchers take on working platform design using DFOS

Long-term health monitoring of levee cutoff wall under Garden Highway in Sacramento by distributed fiber optic sensing (DFOS) technology

USACE (US Army Corps of Engineers) is currently implementing a levee improvement project along the American River in Natomas, California. The main  measure for the levee is a Slag Cement-Cement-Bentonite (SCCB) cutoff wall with an objective to reduce potential for seepage induced distress such as backward erosion piping (BEP) and slope instability. The levee cutoff wall is constructed by a mixture of cement, bentonite and… Read More »Long-term health monitoring of levee cutoff wall under Garden Highway in Sacramento by distributed fiber optic sensing (DFOS) technology
