Interactive engineering model
Trench drain longitudinal flow profile
See flow accumulate along a sloped linear drain and identify stations where normal depth exceeds the channel depth.
Preparing the 3D model...
A cutaway trench set into pavement, with a removable grate, holds a water body that thickens downstream under a uniform lateral-inflow teaching assumption. Stations with no normal-depth solution are hatched instead of drawn.
Focus the 3D view and use the arrow keys to orbit, plus or minus to zoom, and Home to reset the view.
Text explanation and non-WebGL fallback
A cutaway trench set into pavement, with a removable grate, holds a water body that thickens downstream under a uniform lateral-inflow teaching assumption. Stations with no normal-depth solution are hatched instead of drawn.
The numeric controls and readouts remain usable if WebGL is unavailable. Drag or swipe the 3D view to orbit and use a wheel or pinch gesture to zoom. With the 3D view focused, use the arrow keys to orbit, plus or minus to zoom, and Home to reset. The complete numeric lesson is also keyboard-accessible in the adjacent controls and readouts.
