Description

The apparatus is a transparent-sided tank, mounted on a steel-framed bench with work top.
The tank is clear so students can see the flow patterns. The sides are plate glass to resist
abrasion from the permeable medium. The rear of the tank contains pressure tapings. Each
tapping has filter that stop any unwanted particles. The tapings connect to a bank of
piezometer tubes at the side of the apparatus which allow measurement of the head
distribution along the tank. Removable stainless-steel mesh baffles at each end of the tank
hold the permeable medium (usually sand) in place. At each side of the baffles are end
compartments with adjustable overflow pipes for setting the water levels at each end of the
model. The top of the tank is open to allow students to fill the tank and set up model
structures. Supplied are clear, self-sealing plates for students to build models of sheet piling,
walls and simulated dams. Included is a dye-injector system to help show flow lines. Around
the front edge of the glass tank are scales to help students position and measure flow nets
correctly. The self-contained apparatus needs only a mains water supply and drain.
