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

Quality Calibration
Hi, i have a question on the quality calibration of SWMM? what is the allowable error between simulated and observed results for quality modeling? can i know any references for SWMM quality modeling? Thank you.stormwater%20quality%20modeling%20improvements%20needed%20for%20SWMM.pdf…See More
Robert Dickinson commented on Chow Ming Fai's blog post Calibrating total width of catchment using SWMM5
"You should still adjust the width individually for each subcatchment but compare the peak flows for the combined flows to your monitored data. Unless you want to model S1, S2 and S3 together then you are best off estimating the width for each…"

"Thank you for your help. However, the flow measurement was only taken at the outlet of the whole catchment (Out 1). if i want to calibrate the runoff quantity, how can i obtain the width of the whole catchment? Am i combine the total width of…"
Robert Dickinson commented on Chow Ming Fai's blog post Calibrating total width of catchment using SWMM5
"Originally, when SWMM was developed the width parameter was the collection length of the subcatchment. For example, it would be the gutter length on a street going to an inlet. In your case one easy way to estimate the Width for the subcatchment…"

Calibrating total width of catchment using SWMM5
Hello,I am not familiar on using SWMM for quantity and quality modeling. i need some helps here.I have a problem on calibrating the total width of catchment in SWMM quantity modeling. Figure shown below is my studied catchment. the surface runoff is flow from right to left. How can i calculate the total width of catchment? and how to calibrate SWMM quantity modeling on its total width?Hopefully i can get some help from you all. Thank you.See More
