How the Pump Target setting in #SWMM5 works with Initial Conditions

How does the Pump Target setting in #SWMM5 work?  Your pump options, include the initial conditions, the pump on and off depths, the pump type, the pump curve and optional real time rules or RTC Rules.

1. Red is the situation if you start with the Pump with the Wet Well depth greater than the Pump Off Depth. The Pump Setting is greater than zero and the depth is greater than the Pump Off Depth – the pump never turns off.   You need start the pump in the off condition.
2. Purple and Green is the situation when you start the model with the Pump Off.  The Pump then turns on based on the Pump On depth and off based on the Wet Well depth and the Pump off depth.

How is the variable time step option used in #SWMM5

How is the variable time step option used in #SWMM5? - Normally when using the variable time step in SWMM5 (Figure 2), the node time step is equal to the maximum user defined time step, the link time step changes based on a combination of the shortest link, Cr value and Velocity (Figure 1).

Overview of Center for Infrastructure Modeling and Management NCIMM for #SWMM6

The Center for Infrastructure Modeling and Management has been envisaged as an entity that will preserve, promote and extend the US EPA SWMM and EPANETsoftware applications, and potentially other applications.  SWMM and EPANET are two foremost tools for assessment of watershed hydrology and pipe network hydraulics, respectively, and are perhaps unparalleled examples of technical community accomplishments conducted as a partnership of stakeholders from all avenues of professional practice.  Build over decades with participation from regulatory, academic, consulting,  owner/operator, vendors, and institutional support under the continuing leadership of the US EPA, these tools are used around the world as 'first choice' software applications in many, many situations.  They will remain as first choice tools for years to come.  A key question, therefore, is how to ensure these hallmarks of professional practice can be maintained, promoted, and developed going forward.  The expectations of users has evolved, needs have evolved, so the tools and their support mechanisms must evolve along with them.

A visual view of the CDM SWMM5 GUI Circa 2007

This is from a working QA/QC version of SWMM 5.022 showing some feedback from the Simulation Run to the User’s Run Status dialog:

1. You can see the total inflow, outflow, storage and flooding in a graph and text box in the Run Status dialog
2. You can see a running estimate of the Continuity Error (CE) and
3. It stays on the screen when the run as finished.
4. The following images show some examples.
