Subject: What are the Types of Force Mains (FM) in SWMM 5?
There are five ways to model a force main in SWMM 5 for the combination of full and partial flow in the force main (Figure 1):
1. Full Flow using Darcy-Weisbach for the friction l

Stormwater Inlets consist of four main types (http://onlinemanuals.txdot.gov/txdotmanuals/hyd/storm_drain_inlets.htm) with most common shown in Figure 1.
1. Curb opening inlets either at a
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 u

I am trying to model system:
Storage unit (el 100.00), pump, and then forced main and then some outlet (el 104.00) where pipeline connects on gravity sewer system. Slope is always adverse so I am using Dynamic wave.
I started with storage unit, t

This is about the control rules.
I am trying to simulate a network with the help of control rules.
Total simulation period is 2 hrs and 30 minutes, however, I'm running the simulation part by part. Eg 0 to 15 minutes, 15 to 30 minutes, 30 to 45 minu

Purpose: The purpose of this note is to explain a significant dynamic wave routing difference between EPA SWMM 5.0.013 and EPA SWMM 5.0.011 and before. A few people have detected a difference. The previous solution(s) would use only the midpoint
