Water

In the Most region, cultural landscape was destroyed due to the brown coal mining, which included drainage and water management systems that were created over hundreds of years and supported the ecological stability of landscape and its agricultural and forestry functions. The rerouting, with the use of pipes, of the river Bilina through the Ervěnický corridor between Jirkov and Komořany is part of the Podkrušnohorský water supply conduit (in the Lower Ore Mountains) which serves as the entire water supply system of North Bohemia replacing the original local sources of drinking water in the area. Railways, roads and other technical infrastructure projects were similarly rerouted through the same corridor.

Most important interventions include

• Ervě�nice corridor (rerouting Bílina river under the Újezd dam)
• Mostecký corridor (near Ležáky pit mine)
• rerouting of Šramnický and Č�ernický potoka
• etc.

Air

Poisoned by polluted air, forests in the Ore mountains died, and mining threatened remaining healthy beech forests on the southern slopes the Ore Mountains, key to maintaining ecological stability of the region.
