About this digital twin

Żuławy Wiślane is the low-lying delta of the Vistula in northern Poland. This conceptual instrument visualizes how pumping stations and gated connections can manage water in two independent polders.

Navigation

Drag the 3D scene to orbit, scroll to zoom, Shift+drag to pan. TOP and SIDE change camera angle. NIGHT changes lighting.

Operation

Adjust rain, river stage and gate opening. Automatic pumps use level hysteresis. Switch to Manual to command each pump independently. Jump forward one hour.

Mass balance

Water is conserved through rain-driven runoff, seepage, controlled pump discharge, inter-polder transfer and overtopping flow. The displayed balance error should stay close to zero.

Scientific caution

Reservoirs are idealized, crest flows use a broad-crested weir formula, and the tide is sinusoidal. The model uses an arbitrary local datum and illustrative engineering capacities.
