Practice Overview
My practical experience is varied and substantial. My focus is the application of hydrologic and hydraulic
models to the solution of engineering problems — including the U.S. Army Corps of Engineers' HEC-HMS and
HEC-RAS, HEC-SSP statistical software, USGS PeakFQ flood-frequency analysis, and custom analysis using the
open-source R platform. I have substantial experience with the hydrologic and hydraulic components of dam
safety studies — more than 30 completed, mostly in Missouri — and I execute hydraulic modeling studies
addressing the impact of proposed projects on FEMA-regulated floodplains. I also serve as an expert witness
in surface- and ground-water litigation, for both plaintiffs and defendants.
Areas of Expertise
- Hydrologic & hydraulic modeling (HEC-HMS, HEC-RAS 1D/2D, FLO-2D, HEC-SSP, PeakFQ)
- Dam safety analysis, spillway design, and dam-breach / inundation studies
- FEMA floodplain studies — CLOMR/LOMR applications and floodplain mapping review
- Flood frequency analysis and regional regression methods
- Groundwater analysis — well fields, aquifer impacts, seepage/dewatering design
- Expert witness services — surface-water and ground-water litigation and arbitration
- Stormwater management and drainage design
- Climate change impact assessment for water resources and infrastructure
Selected Recent Project & Expert Witness Highlights
