Interactive engineering model
Infiltration trench storage and drawdown
Route a triangular design-volume pulse through aggregate void storage with bottom infiltration, 50-percent sidewall credit, and surface overflow.
Preparing the 3D model...
A cutaway aggregate trench animates a cumulative 24-hour mass balance under a contributing impervious area. Infiltration arrows show full bottom credit and half sidewall credit, and text readouts report storage, cumulative inflow, infiltration, overflow, and the continuity residual.
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 aggregate trench animates a cumulative 24-hour mass balance under a contributing impervious area. Infiltration arrows show full bottom credit and half sidewall credit, and text readouts report storage, cumulative inflow, infiltration, overflow, and the continuity residual.
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.
