Support for Newer Platforms and Operating Systems
SewerGEMS now supports the following:
SWMM Long Term Continuous Simulation
A long term continuous simulation is a simulation that spans multiple storm events and must typically account for things that a single return event would not, such as snow melt and monthly temperature. In previous versions, the SWMM calculation engine had the ability to compute a long term continuous simulation, but the SewerGEMS user interface was mainly designed for single event based simulations. In V8i SELECTseries 2, several features have been added to accommodate long term continuous simulations:
SWMM Interface Files (including Hot Start)
The SWMM calculation engine can use several different kinds of interface files that contains either external imposed inputs (e.g., rainfall or infiltration/inflow hydrograph) or the results of previously run analysis (e.g., runoff or routing results). As of SELECTseries 2, SewerGEMS can now utilize these interface files
SWMM Calculation Engine Update
The Explicit (SWMM) calculation engine has been updated to version 5.0.018. Meaning, when you choose "Explicit" as the "Engine Type" in the calculation options, version 5.0.018 of the calculation engine will be used when you compute a simulation.
SWMM RTK Method
The RTK method available in previous versions of SewerGEMS is different from EPA-SWMM's implementation. In SELECTseries 2, SewerGEMS now supports the SWMM RTK method for estimating RDII.
Catchment to Catchment SWMM Hydrology Support
Easier sharing of data between Implicit Dynamic Wave, SWMM and SewerCAD solvers
Several changes have been made to improve the compatibility between SewerGEMS Sanitary (SewerCAD) and both the implicit and explicit calculation engines in SewerGEMS. This effects cases where you are moving model files between these three calculation engines.
Improvements to the Dynamic Wave Solver (Implicit calculation engine)
Improvements to the Hydrology Calculation Engine
Improved Pond Outlet Structure User Interface
Network Tracing Queries
Advanced network tracing queries can now be performed, from the Network Navigator tool (View > Network Navigator). These can be very useful for cleaning up defects in a model or locating other modeling problems.
More Flexible Date/Time Formatting
In previous versions, time was displayed as either date/time (such as 07/09/2010 7:45 PM) time from start in decimal (such as 7.75) or time from start in clock time (such as 07:45:00). In V8i SELECTseries 2, you can now customize which time format SewerGEMS uses.
In previous versions, only one type of profile was available. This "regular" profile was useful for model review, but lacked some of the things that were more useful for presentation purposes. SELECTseries 2 now includes two profile viewing options: the old style "regular" profile, and a new engineering style profile. Note that any defined profile path can be displayed in either format.
Features of the engineering style profiles include:
Improved Profile Creation
Element Property Inferencing tool
The new Element Property Inferencing tool (located under the Tools menu) allows you to populate missing elevation information. This feature was previously available in SewerCAD and SewerGEMS Sanitary.
Scenario Comparison Tool
In the above example, the infiltration and inflow alternative was different between the two scenarios. One contains inflow information and the other does not.
Hydrology Alternative Editor Improvements
The hydrology alternative dialog box can now be easily filtered, to show only the input fields related to the type of catchment information you're interested in. In the past, this window showed all input fields at once, which was cumbersome since there are many different runoff methods, each with different input fields. For example if all your catchments use the SCS CN loss method, simply click "SCS CN" on the left side, and you'll see only the fields relevant to your model.
You can now export your SewerGEMS model to Inroads Storm and Sanitary as well as import an Inroads drainage database to create a SewerGEMS model.
Formula-based User Data Extensions
In the past, a user data extension always contained user-entered information. Now, you can create a user data extension whose value is calculated based on other existing fields. For example, you can create a field whose value is equal to the square root of the difference between one input field and another user data extension.
You will now have a dropdown at the top of the Element Symbology manager, which allows you to configure which symbology should be applied. For example, you may have one symbology definition for helping you with data input and a few for the different types of presentations you may want to make.
