Hidden features of the 1D St Venant solution for SWMM5, InfoSWMM, and ICM SWMM Networks

🌍 Deep Dive into InfoSWMM SA & Its Nuances 🌊

1/ 🚀 ArcEngine InfoSWMM SA: This variant of InfoSWMM, known as InfoSWMM SA, reveals some fascinating, often overlooked features of the 1D St Venant solution. This extends to software like SWMM5, InfoSWMM, and ICM SWMM Networks. Dive into SA's capabilities with these intriguing output graphs and reports! 🖼️ [Image]

2/ 💾 Software Compatibility: ArcEngine InfoSWMM SA 3.0 is built on ESRI's 10.7 version, while InfoSWMM is more adaptable, running on ArcMap versions ranging from 10.3 to 10.8. 🖼️ [Image]

3/ 🌐 ArcGIS ESRI Software Family: For those curious about how ArcMap fits into the broader ArcGIS ESRI suite, here's a tidbit: ArcMap specializes in 2D spatial data visualization and editing. For a deeper dive, check out ArcGIS Wikipedia. 🖼️ [Image]

4/ 💡 Flow Insights in SWMM5: The SWMM5 engine calculates the flow at the link's midpoint, relying on upstream and downstream hydraulic data. Outputs in this context span Flow, Depth, Capacity, and the Froude Number. 🖼️ [Image]

5/ 📊 Capacity Analysis: In SWMM5, while the flow is gauged at the link's midpoint, associated data like depth and capacity follow suit. Here, "Capacity" is derived from the middle cross-sectional area divided by the full flow area. 🖼️ [Image]

6/ 📈 Velocity in SWMM5: The velocity, a derived output in SWMM5, is calculated using the link's midpoint flow and the depth-related cross-sectional area. 🖼️ [Image]

7/ 🚦 Capacity vs. Surcharge d/D: While SWMM5 displays the capacity (area/full area), InfoSWMM further offers insights into the Surcharged d/D – essentially the average of upstream & downstream depths. A point to note: Capacity ranges between 0 and 1, but Surcharge d/D might exceed 1. 🖼️ [Image]

8/ 🌪 Flow Volume & Froude Number: Both are computed outputs in SWMM5. Notably, the Froude Number works in tandem with the Keep, Dampen, and Ignore parameters, influencing the non-linear term's inclusion/exclusion in the St Venant Equation solution. 🖼️ [Image]

9/ 🌊 Velocity Outputs in SWMM5: Besides the central flow output, SWMM5 provides computed outputs for upstream and downstream velocity, derived from the link's flow and the respective cross-sectional areas. 🖼️ [Image]

10/ 📜 Area in 1D St Venant Solution: This solution leverages upstream and downstream cross-sectional areas, extracted from the respective depths. These play a pivotal role in the solution's non-linear term. 🖼️ [Image]

11/ 📐 Upstream & Downstream Depths in SWMM5: These depths, pivotal in SWMM5, are based on node area rules and the corresponding node depths. Depth essentially is the node depth, but can differ if there are offsets, normal depth, or critical depth. 🖼️ [Image]

InfoSWMM, InfoSewer and InfoWater from Innovyze connection between your model data and your GIS data

One of the great features about InfoSWMM, InfoSewer and InfoWater from Innovyze is the intimate connection between your model data and your GIS data. It is important for this to work correctly that you use the correct spatial reference. Innovyze has many tools for changing the spatial reference:

1. Arc GIS TOC

2. Arc Toolbox projection tools

3. Innovyze tools for changing the spatial reference

4. Innovyze tools for margining spatial reference

5. GIS background maps from ESRI

6. Google Earth and Google Maps connections

Hydraulic Jump and Froude # in #SWMM5

In this blog we example the Froude Number values computed in SWMM5 as equations, table, graphs and units. We use a QA/QC version of SWMM 5 that lists many more link, node, system and Subcatchment variables than the default SWMM 5 GUI and engine. This blog also applies to #InfoSWMM and any software the uses the #SWMM5 engine.  SWMM 5 computes only one flow in the middle of the link but it uses depth, head, cross sectional area and hydraulic radius at the upstream, midpoint and downstream points of the link (Figure 1).  The Froude # is computed at all three points and if you could see the Froude # you will see a jump at times in a single link (Figure 2).

Figure 1.  Computational points in #SWMM5

Figure 2.  Three locations of the Froude Number - it is possible to see where the Hydraulic Jump occurs in the link.

How to See the Highest Continuity Errors Table in the Output Report Manager for #InfoSWMM

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.
