Abstract (in english)
   The 4 km long trench run perpendiculary through a major structure of Bohemian Karst between the floodplain of the Berounka River near villages of Karlštejn and Liteň. It was situated at elevated plateau displayed several important features: 1. The floodplain of Berounka river lies about 4 to 5 km above the present level. It is covered with young (probably younger than the 13th Century) brown flood sediments deposited by high floods. They sometimes contain ice-driven drift pebbles. weassume that during historical high floods the valley was repeatedly flooded to the level about 5 m above the river level. 2. The trench discovered the regular exitence of nowadays destroyed landscape features such as marches, small rocky outcrops, erosional gullies. The modern landscape of the Bohemian Karst underwent intensive planation and it lost its geomorphological diversity.
   Nevertheless, the planation lead also to enhanced sheet erosion which reached such a degree that we can accept a profound loss of soil fertility after 100-200 years of land use when plough horizon will be removed to expose underlying horizons of soils. 3. The solifluction sheets of Pleistocene debris composed of shales of the by Liteň Formation can be observed as well. 4. The studied soil catena of the Bohemian Karst is covered by fluvisols, cambisols mostly with relict properties and gleysols
