Subject: How to use the Flow Splitter in InfoSewer for Dendritic Networks
InfoSewer, which is an extension in Arc Map, does need to have slit split defined where gravity mains merge together to determine the amount of flow in each of the downstream conduits (Figure 1). The options for the flow splitterin each of the downstream links are:1. Automatic Allocation
2. Fixed Flow Percentage
3. Variable Flow Percentage and
4. Inflow-Outflow Curve
At an outfall where the invert of the outfall pipe is raised compared to the inverts of the incoming and outgoing pipes a flow split of Variable Flow Percentage or Inflow/Outflow curve may work better (Figure 2).

Figure 2. The Effect of the flow split can be used to model complex situations in a dendritic model with outfalls.
