Abstract

Gazela gas pipeline is a Czech section of a European Nord Stream gas-line project. Excavations for pipeline laying were dug also in a steep slope east of the Nechranice dam. This dynamic area is historically known for a big landslide, which destroyed the Stranná village in 1820. The earthworks on the slope exposed Miocene sediments of the Most Basin (Most Formation) frequently affected by slope deformations processes. The exposures allowed to document and investigate all slope movements and their succession in detail. Older block-slides as well as younger earthflows and landslides affected this area in the past frequently. The main factors triggering the local landslides are latera erosion of the Ohre River and water-saturated overlaying terrace gravels feeding with water the Miocene clayey sediments.
