### A rise in Pipe Inverts Across a SWMM 5 Node, What Node and Link Invert Elevations Does SWMM 5 Use?

A rise in Pipe Inverts Across a SWMM 5 Node Subject:  This is how SWMM 5 handles  jumps in pipe invert across a node.   The water surface in the node determines the flow in the link, as the depth increases due to upstream inflow eventually the downstream link will start flowing.

What Node and Link Invert Elevations Does SWMM 5 Use? Note:What Node and  Link Invert Elevations Does SWMM 5 Use? SWMM 5 uses the following Node information from the user: ·         Node Invert Elevation, ·         The Node Rim Elevation which is the Node Invert Elevation + the Maximum node depth ·         The Ponded Area when the Ponded  Area option is used ·         The Surcharge Depth above the Node Rim Elevation SWMM 5 uses the following link information from the user: ·         The Link Upstream Offset Depth or Offset Elevation and ·         The Link Downstream Offset Depth or Offset Elevation ·         The Link Maximum Depth or Diameter SWMM 5 calculates the following information internally: ·         The Pipe Crown El…

### @RDICKINSON for @Innovyze on @Medium or my Modeling Posts on Medium

This is a 2014 blogging experiment - a new set of posts on Medium.  I got the idea from @boonsri  The blogs describe @Innovyze software and SWMM5

### Showing Multiple Link Attributes in InfoSewer

This blog shows how to display multiple link parameters.

The 1st method would be to use Arc Map Layer properties and label multiple parameters for each gravity main or force main.  The image below shows and example and here is the code inside of Arc Map to do this

Function FindLabel ( [DIAMETER], [Pipe.SHAPE_Length], [COEFF] )
FindLabel = [DIAMETER] & " m / "  & " " & [Pipe.SHAPE_Length]  &  " m / n "   & [COEFF]
End Function

Or

Function FindLabel ( [DIAMETER], [Pipe.SHAPE_Length], [COEFF] )
FindLabel = " D= " & [DIAMETER] & " m / L="  & " " & [Pipe.SHAPE_Length]  &  " m / n "   & [COEFF]
End Function

The 2nd method is to use Annotation and Map Display in InfoSewer

If you want to show both pipe diameter and slope on the map of InfoSewer you will have to workaround the limitation of having only one map variable:
1.You can map the diameter using Map Display and then
2.Use the Ann…

### InfoSWMM 2D Version 13 Brings Significant 1D and 2D Simulation Advancements To Power Users

InfoSWMM 2D Version 13 Brings Significant 1D and 2D Simulation Advancements To Power Users Latest Release Confirms Product as Leading GIS-centric Urban Drainage Modeling and Management Solution Broomfield, Colorado, USA, November 18, 2014 Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the worldwide availability of the V13 Generation of its industry-leading InfoSWMM 2D for ArcGIS (Esri, Redlands, CA). InfoSWMM 2D delivers new ways to quickly and accurately build and analyze very large and comprehensive two-dimensional (2D) models that reliably simulate complex urban stormwater, sanitary sewers, river flooding and pollutant transport. It allows users to accurately predict the extent and duration of urban and rural flooding for comprehensive stormwater management directly within the powerful ArcGIS environment.

### Arc Map Backwards Compatibility for InfoSWMM

Arc Map Backwards Compatibility for InfoSWMM: Use windows explorer to, make a zero byte mxd file with the same name as your isdb folder, click on the blank mxd file and initialize InfoSWMM or InfoWater, Use the Table of contents to zoom to an InfoSWMM layer, fix the extents of the map in arc gis by using Data Frame, save the Arc Map to make a model in your version of Arc Map

### The 10 year Anniversary of the release of EPA SWMM 5

A colleague mentioned that this is the 10th year anniversary of EPA SWMM 5. I thought this important or noteworthy anniversary was worthy of a short blog.
The release dates for SWMM 5 are from
----------------------- Build 5.0.002 (11/1/04) ----------------------- Engine Updates 1. Modifications made to the Picard method used for dynamic wave    flow routing routine.
------------------------ Build 5.0.001 (10/29/04) ------------------------ First official release of SWMM 5.
since there were 4 releases during a 4 week period, it might be better to consider the whole month the release date for SWMM 5.0.001 to SWMM 5.0.004
Wikipedia has the whole timeline of SWMM 1/2/3/4/5
