1D Pump Sumps

Recommended Posts

I am trying to model a stormwater drainage network that drains down to a small pump sump. The pump is used to pump over sand dunes into a higher drainage system. I think I understand how to pump from a 2D domain into 1D (HS boundary & SC transfer into the 1D), but am at a loss how to create a pump entirely within the 1D domain (i.e. 1D to 1D). This model is running entirely within Tuflow (i.e. no ISIS, etc)

Any assistance will be appreciated,

Thanks Kate - will look into M-channels, though the requirement of 0 flow if the downstream depth matches or is greater than the upstream depth will seriously hinder implementation as a pump I think?
