ŻUŁAWY / DW–04

When wind lifted water.

Żuławy Wiślane, in the Vistula delta of northern Poland, once relied on wind-powered drainage mills, canals and flood embankments. This educational 3D product illustrates how variable wind power can affect pumping between two water bodies.

How it works

Change wind velocity, wind orientation, sail exposure, rainfall and the delivery-gate opening. Pump rate depends on available power and hydraulic lift; a simplified mass balance advances the water levels. The downstream canal discharges over a passive outlet.

Important limitations

This is an original interpretive reconstruction, not a surveyed historical structure or operational design. The mechanism is stylised and uses a two-reservoir educational model, not measured Żuławy hydraulics. All heights use an arbitrary local datum.
