Follow the water. Restore the balance.
This is a stylised educational landscape inspired by the Biebrza River valley in north-eastern Poland, not a digital reproduction of a surveyed location.
Rain adds water, evapotranspiration removes water, and groundwater spreads from wetter to drier neighbouring cells. An artificial drainage ditch exchanges water with its surroundings. Closing the ditch reduces this exchange. A separate river corridor exchanges water with the peatland.
All rates, geometry and controls are illustrative. No real Biebrza National Park measurements are used. The laboratory does not predict flood risk, restoration performance or environmental impacts.
