Robert Dickinson posted a discussionHow is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5?
Subject: How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5? An explanation of the four St. Venant Terms in SWMM 5 and how they change for Gravity Mains and Force Mains. The HGL is the water surface elevation in the upstream and downstream nodes of the link. The HGL for a full link goes from the pipe crown elevation up to the rim elevation of the node + the surcharge depth of the node. The four terms are: dq2 = Time Step * Awtd * (Head Downstream – Head Upstream)…See More
Tributary Area to a Node in InfoSWMM
- Rating: No Rating
Note: Tributary Area to a Node in InfoSWMM
Here are the steps you neeed to take to calculate the tributary area of a node in InfoSWMM:
Step 1: Use the DB Editor to get the total area in your model using the Data Statistics Tool.
Step 2: Use the Process options in InfoSWMM to ONLY simulate surface runoff and flow routing.
Step 3. Copy the Node name and Total Inflow Volume from the Juntion Summary Output Table to Excel
Step 4: Find the Total Wet Weather Flow during the simulation from the Wet Weather Inflow Row in the Flow Continuity Table.
Dry Weather Inflow 0.000 0.000
Wet Weather Inflow 0.782 0.255
Step 5. Make a new column in Excel to calculate the tributary area.
The Tributary Area of a Node = Total Inflow Volume / Total Wet Weather Flow * Total Subcatchment Area from Step 1.
You will now have the tributary area for each node. You can verify this number = the total tributary area at the outfalls should equal the Total Subcatchment Area from Step 1.
