Line 11: Whilst TUFLOW does have a specific syphon channel, there are two approaches to model a syphon system in TUFLOW. === Matrix Flows === The most appropriate approach to model a syphon is to use a M channel, described ~~in Section 5.9 ''M Channels (User Defined Flow Matrix)''~~ in the <u>[https://~~downloads~~docs.tuflow.com/~~TUFLOW~~classic-hpc/~~Releases~~manual/~~Latest~~latest/~~TUFLOW%20Manual.pdf~~ TUFLOW ~~Classic/HPC User~~ Manual ~~2025.0~~]</u>. A M channel can be used to define a matrix of flows between two invert levels based on their respective depths. If this matrix of flows through the syphon can be calculated, or if they are given as part of the operational instructions, then they can be input in .csv form as below, where negative values indicate flows going from downstream to upstream.
