How to Use Scatter Plots in the DB Output tables of #InfoSWMM for d/D and q/Q

Image
How to Use Scatter Plots in the DB Output tables of #InfoSWMM
All of the SWMM5 output tables are available in the output report manager of InfoSWMM and H2OMap SWMM.  A key output table is the conduit summary table where the maximum link values are shown.  You can use the right mouse click to see the statistics, plot, frequency plot, histogram graph and scatter graph for the selected column.  If you select two columns you can make a scatter plot. 
An interesting scatter graph is the d/D or capacity of the pipe versus q/Qfull for the pipe.  Qfull is based on the full pipe depth, area and hydraulic radius using the bed slope.  Due to the fact that InfoSWMM, SWMM5 and H2OMap SWMM use the full St. Venant solution you can have a q/Qfull greater than 1 when the d/D is less than 1.  Here are some St. Venant solution in SWMM5 blogs for reference.

Just a note about the great work being done on the new EPANET and SWMM 5 QGIS interface. This is the third Minimum Testable Product, released for testing of specific functionality.
This is not a fully functional product and is not suitable for production use.—

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

Image
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

More St Venant Equations in #SWMM5

Image
This blog shows the relationship between the terms dq1, dq2, dq3 and dq4 in the SWMM5 code and the St. Venant Partial Differential Equations.
dq2 = Time Step * Area wtd * (Head Downstream – Head Upstream) / Link Length or

dq2 = Time Step * Area wtd * (HGL) / Link Length Qnew = (Qold – dq2 + dq3 + dq4) / ( 1 + dq1) when the force main is full dq3 and dq4 are zero and
Qnew = (Qold – dq2) / ( 1 + dq1) The dq4 term in dynamic.c uses the area upstream (a1) and area downstream (a2), the midpoint velocity, the sigma factor (a function of the link Froude number), the link length and the time step or

dq4 = Time Step * Velocity * Velocity * (a2 – a1) / Link Length * Sigma the dq3 term in dynamic.c uses the current midpoint area (a function of the midpoint depth), the sigma factor and the midpoint velocity

dq3 = 2 * Velocity * ( Amid(current iteration) – Amid (last time step) * Sigma

dq1 = Time Step * RoughFactor / Rwtd^1.333 * |Velocity| The weighted area (Awtd) is used in the dq2 term of the …

Hydraulic Jump and Froude # in #SWMM5

Image
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).

#SWMM5 1-D St Venant Equation Terms

Image
Overview In this blog we show how the St Venant terms are used 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 also applies to #InfoSWMM and any software the uses the #SWMM5 engine. SWMM5 is using is the most advanced equations as it takes into consideration the full dynamic (St. Venant) equations and not the more simplified kinematic wave / manning equations. The manning equation only considers the uniform flow conditions which represents a situation where the gravitational force on a column of water (due to the channel slope) balances out the frictional force. The full dynamic equations contains additional factors that affect the movement of water in a conduit or channel. These include the pressure force due to variation of depth along the length of the channel and the inertial (or convective acceleration) effect due to variation of flow…

#SWMM5 has Topological sorting of conveyance network links

Image
SWMM5 has Topological sorting of conveyance network links in toposort.c  It sorts the network for kinematic wave but also finds the degree of number of links out of a node.  An upstream node has a negative degree and an outfall has a degree of zero.  The degree of the node is used to determine the node composition for the OUTFLOWS file in SWMM 5.  Figure 1 shows the node degrees for a sample network.

The effect of backwater and depth downstream on the links and depths upstream in #SWMM5

Image
Do not forget that the downstream links of your model can affect the d/D and other hydraulic terms in the current link.   The downstream link with backwater raises the downstream link depth which affects the depth and d/D in the link of interest.  For example, The d/D is higher in link CDT-2253 due the effect of a fuller pipe downstream (1).  The d/D is the value in the middle of the link and it averages the downstream and upstream d/D.    The flow in CDT-2249 is 160 and the d/D is 0.47 but even though the flow in CDT-2253 is the same, the d/D is higher as the pipe downstream Pipe-4520 is fuller due to a flow of 425.  The higher d/D in Pipe-4520 means that the downstream d/D of CDT-2253 is higher as
The d/D is the middle value and is the average of the depths at the upstream and downstream points of the link.
CDT-2249 has a d/D of 0.47 as it does not have a downstream effect.
