Calibrated and validated HEC-HMS rainfall-runoff models for 12 sub-basins of the upper Little Colorado River, achieving Nash-Sutcliffe efficiency above 0.78 on peak flows. Built HEC-RAS 1D/2D floodplain models for 9 ephemeral washes supporting county drainage permits and FEMA LOMR submittals. Led post-wildfire debris-flow and runoff assessments for 3 burn scars (31,000+ acres), delivering peak-flow increase estimates to land managers within 14 days of containment. Wrote Python (pandas, xarray) scripts automating gauge data pulls and report figures, cutting monthly reporting time 30%.

Collected ADCP and wading-rod discharge measurements at 18 stream gauges across the Coconino Plateau, maintaining rating curves within 5% of USGS standards. Installed and serviced 25 pressure transducers and tipping-bucket rain gauges, raising telemetry data uptime from 88% to 97%. Sampled surface and spring water quality (pH, conductivity, turbidity, nutrients) at 30 sites under strict chain-of-custody protocols. Mapped riparian restoration reaches in ArcGIS Pro and Field Maps, supporting a $420K watershed restoration grant. Trained 6 seasonal volunteers in field safety, gauging methods, and data entry procedures.

Analyzed 10 years of canal delivery and diversion records to flag 7 reaches with seepage losses above 12%. Digitized 140 miles of lateral canals and turnouts in ArcGIS, improving asset inventory accuracy for operations staff. Assisted with groundwater recharge basin infiltration tests and summarized results in a technical memo for engineers. Built an Excel and Python dashboard tracking weekly water orders for 1,200+ irrigation accounts.

GPA 3.7; Dean's List 6 semesters Relevant coursework: Surface Water Hydrology, Groundwater Hydrology, Fluvial Geomorphology, Watershed Management, GIS for Environmental Science, Hydrologic Modeling, Statistics for Scientists Senior capstone: modeled snowmelt runoff timing for the Rio de Flag watershed using HEC-HMS and SNOTEL data

Lead monthly citizen-science water quality and flow observations at 6 urban stream sites; mentor 10+ new volunteers each year.
