    • Mobile Data Application - Water Quality - Discharge Calculations

    Metadata Updated: January 15, 2026

    FileMakerPro database designed for use on an iPhone to collect/calculate stream discharge data. This FileMaker Pro-based database application was developed by NETN to facilitate discharge data collection in the field. The application was designed for an iPhone but will run on an iPad. The application calculates section areas and at-point velocities, and makes final calculations of total discharge, average velocity, and total area. It also incorporates quality control checks and allows users to graphically display their cross-section. The application exports an Excel spreadsheet that can be e-mailed or downloaded to a computer. All calculations used in this application are based on the USGS's midsection method for computing discharge (http://hydroacoustics.usgs.gov/midsection/).
