A Floodplain Management project by Fain Environmental LLC
- 1D Hydraulic Analysis
- Analyzed FEMA Floodplain Mapping
- Sea-level rise analysis
Location: Aberdeen, Washington
Owner: Climate Impacts Group
Fain Environmental conducted hydrologic and hydraulic analysis and modeling for the Aberdeen Sea-Level Rise Study. We analyzed existing FEMA floodplain mapping. We modified an existing Hydrologic Engineering Center-River Analysis System (HEC-RAS) model of the Chehalis River to calculate 19 different sea-level rise and flow scenarios. Fain Environmental assisted in preparation for public meetings to discuss the implications of the modeling results.
