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

Rules for using the NRCS (SCS) Dimensionless Unit Hydrograph Method in InfoSWMM and InfoSWMM SA
A unit hydrograph is defined as the direct runoff hydrograph resulting from a unit depth of excess (effective) rainfall produced by a storm of uniform intensity and specified duration. Unit hydrographs could be natural … Read the rest
Infiltration is the process of rainfall penetrating the ground surface into the soil over the pervious areas of Subcatchments.

How to Use the Clark Unit Hydrograph Method in InfoSWMM and InfoSWMM SA
Clark’s method derives a unit hydrograph by explicitly representing the processes of translation and attenuation, which are the two critical phenomena in transformation of excess rainfall to runoff hydrograph. Translation refers to the movement, without storage, of … Read the rest
