hi
can Swmm Calculate the velocity in a junction? I know that we can calculate the velocity in the pipes but i wanna the velocity in a Junctio
Thank you

Good question, there is no explicit routing in a junction, the node depth is calculated based on the equation dH/dt = dQ/dA where H is the depth, Q is the Flow and A is the node area
However, if you use a storage node you can approximate the velocity in the node by dividing the storage volume by the total inflow to get the velocity - you will have to include the depth to get the right units
How can I include the depth ??
