Unit Hydrographs

Unit Hydrographs (UHs) estimate rainfall-dependent inflow/infiltration (RDII) into a sewer system. A UH set contains up to three such hydrographs, one for a short-term response, one for an intermediate-term response, and one for a long-term response. A UH group can have up to 12 UH … Read the rest

Tutorial – Step 9: Export Results to InfoSWMM and InfoSWMM SA RDII Analyst

Step 9: Export Results to InfoSWMMand InfoSWMM SA

In this section, you will export the hourly DWF patterns created for weekdays and weekend, the groundwater inflow time series and the RTK parameters to InfoSWMM and InfoSWMM SA. The exported data would be assigned to the nodes that contribute flow to … Read the rest

Tutorial – Step 8. Calibrate the RTK Hydrograph Parameters for InfoSWMM RDII Analyst

Step 8. Calibrate the RTK Hydrograph Parameters

Automated calibration is another powerful tool that RDII Analyst offers. The calibration tool identifies optimal parameters of the RTK hydrograph to match the RDII flow simulated by InfoSWMM H2OMAP SWMM with the RDII time series identified by RDII Analyst using the decomposition process … Read the rest
