More St Venant Equations in #SWMM5

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 St. Venant equation:

dq2 = Time Step * Awtd * (Head Downstream – Head Upstream) / Link Length

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 area along the channel length. Because of these additional terms the flow/head relation you have in uniform flow conditions can be completely different according to the configuration of his network.

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).

How are the St Venant Terms used in SWMM5?

Figure 1 shows the terms and Figure 2  and Figure 3 shows the terms in a SWMM5 table and SWMM5 graph. 

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

You can also see the QA/QC report for SWMM 5 https://www.epa.gov/water-research/storm-water-management-model-swmm#downloads

How are the St Venant Units used in #SWMM5?

The new flow (Q) calculated at during each iteration of time step as

(1) Q for the new iteration = (Q at the Old Time Step – DQ2 + DQ3 + DQ4 ) / ( 1.0 + DQ1 + DQ5)

In which DQ2, DQ3 and DQ4 all have units of flow (note internally SWMM 5 has units of CFS and the flows are converted to the user units in the output file, graphs and tables of SWMM 5).

The equations and units for DQ2, DQ3 and DQ4 are:

(2) Units of DQ2 = DT * GRAVITY * aWtd * ( H2 – H1) / Length = second * feet/second^2 * feet^2 * feet / feet = feet^3/second = CFS

(3) Units of DQ3 = 2 * Velocity * ( aMid – aOld) * Sigma = feet/second * feet^2 = feet^3/second = CFS

(4) Units of DQ4 = DT * Velocity * Velocity * ( aMid – aOld) * Sigma / Length = second * feet/second * feet/second * feet^2 / feet = feet^3/second = CFS

The equations and units for DQ1 and DQ5 are:

(5) Units of DQ1 = DT * GRAVITY * (n/PHI)^2 * Velocity / Hydraulic Radius^1.333 = second * feet/second^2 * second^2 * feet^1/3 * feet/second / feet^1.33 = Dimensionless

(6) Units of DQ5 = K * Q / Area / 2 / Length * DT = feet^3/second * 1/feet^2 * 1/feet * second = Dimensionless

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

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.

How to Make Break Nodes in #INFOSWMM and #H2OMAP SWMM

How to Make Break Nodes in #INFOSWMM and #H2OMAP SWMM

You would add a break node to break up long force mains so that the pipe(s) react faster to the pump flows.

1. Find your long FM or long  Gravity Main links
2. Insert a Node into the middle of the link to break the link into two links with the same geometry but different lengths
3. Use the Node Inference tool to estimate the new nodes invert based on the immediate upstream and downstream node inverts
4.  If you make a new for a FM, please also use this tool  

which will set the Surcharge depth – 1000 is bit high. 

Steps used to Insert Nodes in a Force Main

InfoSWMM and the Custom Report Tool

Step 0 is to define the domain and use the Custom tool in Tools,

Step 1 is to define the data source

Step 2 is to define the fields to show in the table

Step 3 is to define the source (click on Domain) and

Step 4 is to view the output table.

The Impact of the yCrown Taper equation in #SWMM5 on Surcharged Nodes

The Impact of the yCrown Taper equation in #SWMM5

We are looking at three ranges of depth in the node:
1.  Node depths below yCrown using the node continuity equation to compute the new node depth,
2. Node Depths above 1.25 * yCrown use the point iteration solution for the node in which there is no node area and the program iterates until the sum of flows is zero for the timestep.
3.  Node Depths between yCrown and 1.25 * yCrown use the taper equation in which the node area decreases from the area at 0.96 Full Depth to a value of zero area at 1.25 yCrown.

If the current depth in the node is below 1.25 * yCrown

Where,  yCrown is the depth till the highest connecting conduit crown elevation

There is a tapered equation based on the sum of the  flow at the node and the surface area from the last non-surcharged condition which will influence dqdh if depth close to crown depth

F = yLast/yCrown – 1

Denom = Sum DQDH for all connecting links to the node

Denom = Denom + (Old Surface Area (at last non-surcharged condition) / dt (time step) – Sum DQDH term for connecting links ) * exp (-15*f)

This has the effect of quickly tapering the impact of the Old Surface Area between yCrown and 1.25 * yCrown (Figure 1 and Table 1).  It starts out at the value of Old Surface Area and by a depth of 1.25*yCrown the impact of Old Surface Area is zero.
