Flood Risk Information & Modeling

Riverine and inland flooding is a significant risk to both
life and built assets

Having reliable flood depths and extents for future precipitation events is critical to assessing risk and developing meaningful mitigation strategies. At BSC, our multi-disciplinary team of climate, hydrology, engineers, data and remote sensing specialists, and software engineers have developed innovative methods and procedures to efficiently model large areas for pluvial/fluvial flooding events based on best available climate and rainfall projections.

Regional Climate Hazard Modeling

BSC has worked to develop an approach to regional/state-scale modeling that provides full geographic coverage, including rural areas, and can be customized using local geospatial data, precipitation projections, and return periods. We capture a greater extent of flood-prone areas, compared to FEMA maps, by incorporating forward-looking precipitation data, including lower order streams that other maps might omit, and model multiple design storms leading to a nuanced inundation pattern, especially in areas surrounding minor rivers.


Hydrologic & Hydraulic Modeling for Design

BSC has extensive experience performing hydrologic & hydraulic modeling of riverine settings throughout New England in support of culvert and bridge replacement projects. BSC utilizes the latest modeling software, including ArcGIS, HEC-RAS, HY-8, and HydroCAD, to analyze the project site and design resilient structures.


BSC Modeling Software and Infrastructure

Although flood modeling involves significant judgement and orchestration on the part of experienced and highly trained modelers/experts, there are many aspects of the modeling pipeline that are routine and very time-consuming. In addition, the modeling process is highly iterative and new information such as new drainage and impounding structures like culverts and dams often needs to be added to the models after base models are created.

Modeling large areas such as states or regions requires significant computational resources. In order to perform modeling at this scale and in a cost-effective and timely manner, a fully automated data processing pipeline has been developed by BSC to streamline many labor-intensive functions, such as input data preprocessing, automated simulation queueing, and processing.

BSC has developed a proprietary flood modeling processing server farm that allows simultaneous simulation processes to be run without human interaction. The system utilizes a variety of plugins that allow interoperability with various modeling packages and environments.

To ensure consistent and reliable output data, the system interfaces with GIS data and remote sensing data to automate and standardize many time-consuming and error-prone tasks.
