Hydraulic Model Calibration Data
15-minute dry weather flow datasets and RDII parameters formatted for direct import into EPA SWMM, InfoWorks ICM, SewerGEMS, XPSWMM, and ESRI.
Model Calibration
Turn monitoring data into model-ready intelligence
US3 supports hydraulic model calibration with time-series flow data, dry-weather patterns, wet-weather response, and engineering-ready exports.
What This Service Is
US3 provides field-measured calibration data that makes hydraulic models accurate. Models built on assumed flow patterns misrepresent actual conditions by 30–65% — leading to oversized capital projects and capacity evaluations that fail under regulatory review.
Why Municipal Utilities Need It
Regulators and permitting agencies require hydraulic models calibrated against measured field data. Uncalibrated models are not accepted for consent decree submittals, capacity certifications, or capital improvement justifications.
How the Process Works
DWF Diurnal Patterns: 15-minute interval dry weather flow time series — average daily flow, peak hour flow, and minimum night flow derived from continuous sewer flow monitoring.
RDII Parameters: R, T, and K values calibrated against observed storm events using SSOAP software — direct inputs for EPA SWMM and similar platforms.
Compatible platforms: EPA SWMM, InfoWorks ICM, SewerGEMS, XPSWMM, ESRI. US3 coordinates format requirements with your modeling engineer before fieldwork begins.
Typical Project Workflow
DWF calibration: 14–21 days minimum. Full DWF + RDII calibration: 3–6 months. US3 delivers interim DWF data early while wet weather collection continues.
