Robert Dickinson replied to Robert Dickinson's discussion How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5?"Subject: Link Iterations in the SWMM 5 Dynamic Wave Solution
Each of the links in the SWMM 5 network can use up to 8 iterations to reach convergence during a time step in the dynamic wave solution of SWMM 5. The rules…"

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
