Interactive engineering model
Level-pool detention routing
Route a triangular inflow through a fixed 260 by 160 ft cutaway basin and an illustrative orifice-and-weir outlet using storage-indication (Modified Puls) continuity.
Preparing the 3D model...
A ponded water prism rises inside a cutaway basin past a circular orifice and a rectangular weir notch, against a stage staff, a weir-crest datum, and a peak-stage datum, while a Modified Puls route compares inflow and outflow and reports its continuity residual. Depth is drawn with an announced vertical exaggeration. The outlet controls teach routing behavior and are not calculator-parity inputs.
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 ponded water prism rises inside a cutaway basin past a circular orifice and a rectangular weir notch, against a stage staff, a weir-crest datum, and a peak-stage datum, while a Modified Puls route compares inflow and outflow and reports its continuity residual. Depth is drawn with an announced vertical exaggeration. The outlet controls teach routing behavior and are not calculator-parity inputs.
Important: Pedagogical outlet controls — use the calculator's stage-storage-discharge table for design routing.
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. This model is an educational aid and does not replace applicable design standards or professional review.
