Flux32 Software for Load Estimation

Flux32 Software for Load Estimation is a U.S. Army Corps of Engineers (USACE) tool designed to estimate constituent loads—such as nutrients, sediment, and other water-quality parameters—from paired concentration and streamflow data. It helps practitioners translate monitoring results into defensible estimates of transport over time, supporting regulatory, planning, and restoration decisions.

The software implements standard load-estimation approaches used in water-quality analysis and reporting. By combining concentration measurements with discharge records, Flux32 calculates period-specific and annual loads, flow-weighted mean concentrations, and related summary statistics, with options to evaluate uncertainty and potential bias.

Key capabilities include:

• Multiple estimation methods (e.g., stratified, period-weighted, and regression/rating-curve approaches) to match data availability and site behavior
• Computation of loads over user-defined intervals (event, seasonal, monthly, annual) and flow-weighted mean concentrations
• Data screening and quality-control utilities, including unit handling and missing-data checks
• Import and export of common data formats to streamline workflows and reporting
• Clear, auditable outputs with tables and graphics suitable for documentation and stakeholder communication

Typical applications:

• Watershed and receiving-water assessments
• TMDL development and evaluation
• Permit and compliance reporting
• Project and restoration performance tracking
• Support for linked water-quality models and decision tools

Developed by USACE, Flux32 is intended for environmental professionals, agencies, consultants, and researchers who need transparent, reproducible load estimates grounded in accepted methods.
