Calibration Functions for the InfoSWMM and InfoSWMM SA Calibrator
When calibrating a Stormwater management model, the goal is to determine the best set of InfoSWMM model parameters which produces the lowest overall deviation between the numerically simulated model results and the observed field data at user specified locations in the … Read the rest
LID Results - Summary Report
The performance of the LID controls placed in a Subcatchment is reflected in the overall runoff, infiltration, and evaporation rates computed for the Subcatchment as normally reported by SWMM5. The SWMM's Output Modeling Report also contains a section entitled LID Performance Summary that provides an … Read the rest
Excerpt from the EPA manual Storm Water Management Model Reference Manual Volume III – Water Quality (PDF) which can be found here
Management of stormwater quality is usually performed through a combination of so-called “best management practices” (BMPs) and a form … Read the rest
Problem: As SWMM5 is a link node network, the area of a Storage Node is both the area of the Wet Well and typically ½ the surface area of the connecting links. There is no surface area for the Pump(s) downstream of the Wet Well (Storage) but the area of … Read the rest

Objective Functions in the Genetic Algorithm of InfoSWMM and InfoSWMM SA
The objective of the optimal calibration problem is to minimize the numerical discrepancy between the observed and predicted values of link flow, link depth, and/or link velocity at various locations in the system. Any of the following five different … Read the rest
Calibration Methodology
The successful application of a sewer collection system model to the planning, design, and management of urban stormwater systems is highly dependent upon how well the model is calibrated and how well the model mimics the reality. Model calibration consists of fine tuning of model parameters until the … Read the rest
