Robert E 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 subcat…

Chow Ming Fai commented on Chow Ming Fai's blog post 'Calibrating total width of catchment using SWMM5'
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 subcat…

Robert E 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 goi…
