PRĄDY / L–38

This is an interactive educational model inspired by the Prądy lock on Poland's Bydgoszcz Canal. It is not a surveyed replica or a navigation safety tool.

Manual upstream passage

  1. Open the downstream gate while levels are equal.
  2. Use Move vessel to enter the chamber.
  3. Close the downstream gate, then open the upper sluice.
  4. Once chamber water reaches the upstream level, close the sluice.
  5. Open the upstream gate, move the vessel out and close the gate.

Hydraulic model

Water flows through a simplified sluice orifice: Q = Cd · A · √(2gΔh). Chamber level changes by dh/dt = Q / (L × W). Gate opening is blocked unless water heads are within 0.065 m. Displayed hydraulic time accelerates according to the selected speed; animated gate and vessel movements remain visually paced.

Parameters: chamber 57.4 × 9.6 m, nominal head 3.82 m, idealised orifice 1.4 m², discharge coefficient 0.62. These are a blend of reference lock dimensions and explicitly illustrative hydraulic assumptions, not certified plant operating values.

Navigation

Drag the 3D view to orbit, use the mouse wheel or pinch to zoom, Shift-drag to pan and double-click to reset the camera. Press Space to pause or R to reset.
