I need to be able to turn off the water supply to a unit am working on. However, I have no idea where to look for the water shutoff. (For ex., in most houses in the US (AL), there'd be a little gutter in the ground where I could twist a knob and that would disconnect the water supply to the house)

In the second screenshot the nodes and links downstream of the steep link result in the downstream water level for that link to be high. The downstream water level is high, and as a result the water level at the mid point of the conduit is high – the pipe is approx half full. The high water level at mid point leads to a high cross section area of flow in the pipe and hence a (comparitively) low velocity. The calculated maximum velocity for the link shown in this configuration is 5.83m/s

There should be an isolation valve that controls your apartment’s water only. It’s usually under the laundry sink, but also look under the kitchen sink. Look for a tap that appears to be doing nothing. Draw its location and tape it inside the pantry door.

When it comes to locating shut-off valves, it seems antipodeans are more ruggedly individualistic than the more conformist locales I inhabit.

The velocity calculations for pipes at steep grades are sensitive to tailwater conditions (or to the water levels in the downstream node).

Under open channel conditions (part-full pipe flow) , the mid-channel depth is the average of the upstream and downstream depths. The velocity will be different at the upstream, mid-conduit, and downstream ends of the conduit.

In the first screenshot below the tailwater level (the downstream water level) for the steep link is determined by 12d Model (using critical depth and normal depth equations). The downstream water level is low, and as a result the water level at the mid point of the conduit is low – the pipe is approx quarter full. The low water level at midpoint leads to a low cross section area of the flow in the pipe, and a hence a high velocity. The calculated maximum velocity for this link shown in this configuration is 9.05m/s

You’ll find the valve near the front of your property ... our valve is located inside the front fence near the boundary with our neighbour. For those of you with larger properties, it might be outside the front fence.

use the main shutoff valve to turn off the water supply to the entire house. You'll find the main shutoff valve on the inside or outside of your house where the main water supply pipe enters. Turn the valve clockwise to shut it off.
