Air Trapping Simulation Results for Stormwater Conduits

A technical report from 2025 provides data and results supporting a study using the EPA Storm Water Management Model (SWMM). The data includes simulation results for entrapped air volume against inflow bias and other metrics, exploring effects of manhole diameter and inflow rise. The full test set included 15 different bottom slopes, though reported results are limited to three.

Use Cases

• Analyzing the relationship between entrapped air volume and inflow bias based on the reported data graphics.
• Evaluating the effect of manhole diameter on air trapping based on the described exploration.
• Comparing the impact of gradual versus sharp inflow rises on simulation outcomes.
• Validating hydraulic models using the centroid metric for trapped volume envelopes.

Strengths

• Results are tied to a specific 2025 technical report, providing clear context.
• Simulations explore a range of 15 bottom slopes, indicating systematic parameter testing.
• Analysis includes specific dimensionless metrics like V_e*, ΔQ*, Q_T*, and Q_e*.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
