How to Understand your Hydraulics Output using InfoSWMM and InfoSWMM SA 2D and 3D Linked Graphics

InfoSWMM v 14.6 and InfoSWMM SA v2 (InfoSWMM SA is a not an Esri Extension in ArcMap) has many new graphical and map display tools that help answer the following modeling questions in a easy to understand group of linked Time Track Graph, 2D Graphs and 2D Thumbnails:

  1. How do the flows, depths, velocities, Froude Number, d/D, surcharged d/D change over time?
  2. Let’s you see a thumbnail of surcharged d/D in my Output Report Manager graphs,
  3. You can see the maximum, minimum and current surcharged d/D at any time in the Atrribute Browser (AB),
  4. Using the Time Track you can link the thumbnail, graphs, 2D view of the links in the AB and the Map Display on the Map of ArcMap or Arc Engine in InfoSWMM SA
  5. See Figure 1 for an example of how the Time Track connects all graphs and views.

Images of how each of the 24 shapes in InfoSWMM and InfoSWMM SA are shown in the linked 2D, Graph and Attribute Browser

Here is a graphical view of the nonlinear runoff processes in InfoSWMM and SWMM5:
1. Three runoff surfaces
a. Impervious with Depression Storage
b. Pervious
c. Impervious without Depression Storage
2. Evaporation
a. Constant
b. Time Series
c. Monthly
d. Temperature
e. Climate File
f. Monthly Adjustments for Climate Change
3. Slope (same for all runoff surfaces)
4. Infiltration
a. Horton
b. Modified Horton
c. Green Ampt
d. Modified Green Ampt
e. Curve Number or SCS or CN
f. Monthly Adjustments for Climate Change for all Infiltration Methods
5. Roughness (Manning’s n)
a. Impervious
b. Pervious
6. Width or the Dimension of the Subcatchment (same for all runoff surfaces)
7. Wind Speed for Snowmelt
a. Climate File
b. Time Series
