5.2.1   Permanent Flow Meter Data
Model calibration is a crucial component of the hydraulic modeling effort. The model must be calibrated to match flow metering data to ensure the most accurate results possible.
The City has permanent flow meters near the bottom of the collection system on major trunk lines. Data from these meters was analyzed for the period of January 1, 2019 to June 2, 2019. Table 5-1 provides a summary of the data for the four major meters during the selected time period, including the average flow, maximum flow, and peaking factor. The 7800 South trunk line is the largest of the main trunk lines within the City, and thus carries the highest flow.
