THE SCIENCE FORMULAS & ASSUMPTIONS

Operating principle: A lock raises or lowers a vessel by moving water through controlled passages into or out of an enclosed chamber.

h = H(1 − f)

Q = C_d A_v √(2gh)

dz/dt = Q / (LW)

V = LWHf

P = ρgQh

g = 9.81 m/s²; ρ = 1000 kg/m³; C_d = 0.68; L = 32 m; W = 12 m. Valve area at 100% opening = 1.8 m². f is the fraction filled and H the selected lift.

These are idealised, quasi-steady orifice relationships, not a prediction of actual filling time. Water inertia, surge, valve ramps, lock hydraulics, wave motion and detailed safety controls are not modelled.

WHERE & WHEN

The Dnipro, Ukraine

Navigation locks are associated with major 20th-century river engineering along the Dnipro; this is a generic composite rather than one specific historical installation.

WHY IT MATTERED

Connecting waterways

Locks make it possible for river traffic to cross different water levels, linking navigable reaches without lifting the vessel mechanically.
