Hydraulic Model Verification
Level + Visual
Hydraulic MOdel TRUTHING
A hydraulic model was built for the City of Carterville MO collection system in 2017 using available flow monitoring data available from 2011. Once the model was built, PreView sensors were installed to gather level + visual data at approximately 12 sensor points throughout the system to verify the accuracy of the model and make corrections where needed. The predicted hydraulic grade line for the 2017 rain events was plotted against the actual level data measured by PreView sensors. Results were used to further refine hydraulic model to match pipe conditions and rainfall derived infiltration and inflow projections.
