1D and 2D HEC-RAS modeling through FEMA submission — most floodplain submissions fail on completeness, not technical merit.
1D & 2D HEC-RAS Modeling
Steady and unsteady-flow hydraulic modeling for riverine, urban, and coastal-adjacent systems. 1D for clean channelized flow; 2D for overbank, urban grid, and complex floodplain interaction where 1D assumptions break down. Models delivered with documented input data, parameter assumptions, sensitivity notes, and a clean output package.
Local & FEMA Floodplain Studies
No-rise certifications, floodplain encroachment analyses, CLOMR/LOMR submissions, and county-level floodplain development permits. The alternatives analysis and detailed work map FEMA actually requires — most submissions fail on completeness, not technical merit.
Inundation, Velocity & Scour Mapping
2D HEC-RAS output mapping for dam-break analysis, levee/embankment failure scenarios, and structure-protection studies. Velocity and shear-stress mapping for scour assessment at bridges, culverts, and stream restoration features.
Civil site design, from feasibility to record plat.
