Agency capabilities
Five areas of agency work, each with a recent project.
Watershed, riverine & stormwater H&H
Floodplain and watershed studies, reservoir and canal design support, level-of-service analysis.
HEC-RAS, HEC-HMS, ICPR, SWMM, MIKEPrecipitation frequency & national-scale hydrology
Extreme-rainfall statistics, non-stationary frequency analysis, and large hydrologic datasets.
Python, R, statistical and GIS pipelinesRecent workNOAA Atlas 15, with IBSS and RTIGroundwater & integrated surface water–groundwater
Coupled models where the water table drives flooding, wetlands, and water supply.
MIKE SHE, MODFLOW, MODHMSEcosystem restoration & water quality
Wetland restoration performance, backwater channels, sedimentation, and nutrient transport.
ICPR 2D, HEC-RAS, WASP, MIKE ECO LabData, tools, training & model review
Custom pre/post-processing tools, real-time monitoring models, peer review, and software training.
Python, C#, MATLAB, GitHub
Selected agency projects
As a prime contractor and as a subconsultant to national engineering and research firms.
NOAA Atlas 15 Precipitation Frequency Estimates
Developing the non-stationary precipitation frequency estimates that will replace Atlas 14 as the national standard.

2017–2018View project →Silver/Twin Lakes Watershed Master Plan
Stormwater geodatabase, SWMM model, flood mapping, level of service, and cost-estimated alternatives.
2018–2021View project →Ways to work with us
We hold our own contract vehicle, and we regularly team with larger firms that need a modeling specialist.
Order through GSA
Federal agencies can order our professional engineering services through our GSA Multiple Award Schedule contract (47QRAA22D009K).
Team with us as a subconsultant
Primes including Atkins, Stantec, Carollo, HDR, and McKim & Creed have brought us in for the modeling piece. We work to your standards and schedule.
