How do you interpret the Flow and Hydrology Summary Tables in SWMM 5.1? Interpretation of the Tables..

How to See the Highest Continuity Errors Table in the Output Report Manager for #InfoSWMM In the output text report file of infoSWMM and H2OMap SWMM there is the Highest Node Continuity Error Table. The Table shows the highest 20 Nodes for percent node continuity errors and the actual continuity error as defined by Node Outflow – Node Inflow. This table is also shown in the Output Report Manger table  The same value of Node Outflow – Node Inflow is shown in the Junction Summary table under the column flow volume difference. The units of flow volume difference will be the same as the RPT file if the units are changed in the Output Unit Manger. How to change the volume units in the Output Unit Manger. Change the volume to MG or ML (for SI units). The flow volume difference can also be seen in Map Display by picking the Active Output variable Vol_Diff or Flow Volume Difference. SHARE THIS:

How to Rectify Offset Issues in InfoSWMM and H2OMap SWMM 1. Use Tool preferences to use elevation Rim Elevations (instead of depths) and elevation link offsets (instead of depths) 2. Once these flags are set you need to divide all of the link offsets by 2 to get the original values 3. The node and links should be correct 4. Check a portion of your model using the Input HGL tool to see if the offsets make sense 5. You should always check to see if you have the right elevation preferences a. Offsets of depth and Node Max Depth or b. Offsets of absolute elevation and Rim Absolute Elevations instead of Depths

How does a PID controller work in  InfoSWMM  and SWMMM 5 - this also applies to H2OMap SWMM?? double getPIDSetting(struct TAction* a, double dt)   //  at each time  step find  the PID control  changes for the  current  time step dt // Input: a = an action object // dt = current time step (days) // Output: returns a new link setting // Purpose: computes a new setting for a link subject to a PID controller. // Note: a->kp = gain coefficient, // a->ki = integral time (minutes) // a->k2 = derivative time (minutes) // a->e1 = error from previous time step // a->e2 = error from two time steps ago { double e0, setting; double p, i, d, update; double tolerance = 0.0001; // --- convert time step from days to minutes dt *= 1440.0; // --- determine relative error in achieving controller set point // Or how close are we to the set point? e0 = SetPoint - ControlValue; if ( fabs(e0) > TINY ) { if ( SetPoint != 0.0 ) e0 = e0/SetPoint; // n...

Innovyze Further Expands RDII Analyst Functionality, Setting New Standard for Sanitary and Combined Sewer System Model Calibration New Features Allow Unprecedented Analysis and Comparison of Rainfall-Derived Inflow and Infiltration Data, Parameters for Complex Sewers Broomfield, Colorado, USA, March 15, 2016 Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the newest release of its  RDII Analyst  (Rainfall-Derived Inflow and Infiltration) for  InfoSWMM  and  H 2 OMAP SWMM . The new version delivers expanded functionality, incorporating many advanced Genetic Algorithm (GA) optimization features. It increases its unmatched productivity by making it easy for users to further adjust the dry weather flow (DWF) and RTK parameters (with initial and maximum monthly storages for continuous simulation) to achieve a better fit and ultimately a better model based on their experiences. The...

How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM  w/ #SWMM5 Find the Fraction of Normal Flow Limited in the Flow Classification  Table and copy it to the Link Information Table - the value of FLM can then be Displayed in a Map using  the Map Display command.  In this small example, three links primarily used normal flow and one uses it for a short time. Normal flow only uses the Manning's equation and the link upstream depth, hydraulic radius and cross sectional area to compute the flow. How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM  w/ #SWMM5 St. Venant equation  solution – this is the link attribute data used when the St. Venant Equation is used in #SWMM 5. Simulated Parameters from the upstream, midpoint and downstream sections of the link are used. Normal Flow Equation  – this is the link attribute data used when the Normal Flow Equation is used in #SWMM 5. Onl...

Steps in #INFOSWMM for Using and Saving Hot Start Files for Quasi Steady State Runs 1. Two Scenario's to Save and then Use a Hot Start File  2. Save and Use the Hot Start Files  3. Graph the Depth and Flow of the Scenario that uses the Hot Start File, the depths and flows should be connstant  4. You can see the time step values in the Attribute Browser  5. Map Display Depth on the Map to see the flows and depths are steady Steps in  #INFOSWMM  for Using and Saving Hot Start Files for Quasi Steady State Runs
