2D Waterfall Canyon: Discharge & Impact Physics

Interactive 2D side-view waterfall lab: free-fall kinematics set the impact velocity and fall time from cliff height, continuity conservation tapers the falling curtain from the discharge rate, an overhang slider launches the water outward on a real parabolic arc, and wind bends the rising mist. Live Reynolds number and hydraulic power readouts track the flow.

A 2D canvas side-view companion to the 3D waterfall canyon scene, built around the real hydraulics behind a falling curtain of water: free-fall kinematics set the impact velocity and fall time from the cliff height, continuity conservation tapers the water curtain as it accelerates downward from a chosen discharge rate, and a ledge-overhang slider launches it outward on a true parabolic arc instead of hugging the rock face. Wind bends only the light spray and rising mist above the pool — the heavy main curtain is too massive to steer — while live Reynolds-number and hydraulic-power readouts track the flow's real-world scale.

⚙ Under the hood

Free-fall kinematics, continuity-based curtain tapering, and a parabolic overhang launch drive a real waterfall model, with live Reynolds number and hydraulic power readouts.
