RIVER ENGINEERING / UKRAINE
An interactive engineering model of how a chamber lifts a vessel between two river levels through controlled filling and gate operation.
01 / OPERATING PRINCIPLE
Closed gates enclose a water-filled chamber. Controlled flow through a valve system raises or lowers the chamber surface until it aligns with the adjacent river reach, allowing a vessel to pass.
Principle: hydrostatic equilibrium and continuity of water volume.02 / WHERE & WHEN
Place: Dnipro River basin, Ukraine. Era: a composite of twentieth-century navigation-lock engineering, interpreted for modern learners. Actual locks on the river differ in gate type, dimensions, filling arrangements and chronology.
This scene is not a surveyed or official reconstruction of any particular installation.03 / WHY IT MATTERED
Locks help inland vessels travel between river reaches separated by hydraulic structures or natural changes of level. Their engineering brings together civil works, mechanical motion, hydraulic flow and operational safety.
The model uses intentionally hypothetical teaching dimensions.ENGINEERING EXPLAINED
Δh = Hupper − Hchamber. At equal datum depth, Δp = ρgΔh. For fresh water, ρ ≈ 1000 kg/m³; g = 9.81 m/s². The independent check is γΔh, where γ = 9.81 kN/m³.
Q = CdA f √(2gΔh), using Cd = 0.62, total open area A = 1.8 m², and opening fraction f. ΔV = L W Δz with illustrative L = 56 m and W = 12 m. P = ρgQΔh estimates instantaneous hydraulic power.
A simple orifice equation is used; actual filling systems require unsteady-flow and vessel-force analysis. The display omits distributed head loss, inertia, lockage safety interlocks and longitudinal water-surface slope. The changing fill animation is illustrative, not a solved time integration. Chamber geometry and mechanisms are a generic reconstruction, not an as-built survey.
Illustrative reconstruction, not an official model and not affiliated with any institution, company or manufacturer.
