The village of Vohančice is located in a sloping terrain threatened by water and wind erosion. Climatic conditions in the village are severely disturbed, summer temperatures reach tropical values, the groundwater level has reached a critical limit. Torrential rains washed away the top layers of soil from the fields and carried them into the village. The retention capacity of the landscape was zero. The project deals with anti-erosion and landscaping. 30 ha of fields were grassed, 2 terrain embankments with retention capacity were implemented and 800 trees were planted in the landscape around the restored field roads.

The project suggested disposing of rainwater in the form of retention in surface objects, i.e. grassy overhangs, or other landscaping in the given area in combination with appropriate planting, which will allow the capture of stormwater and its gradual seepage only into the upper horizons. When designing the given measures, it is necessary to start from the requirement that the water level in the surface retentions should not exceed approx. 0.2 m, when the slopes of the overhang will have a minimum slope of 1:2.5. The stated requirement is conditional on sufficient retention space in relation to the possible maximum amount of storm water. The surface of the beds was provided with a layer of well-permeable humus soil and grassed. The actual design solved the disposal of rainwater by seepage into the unsaturated zone of the rock environment, which was in accordance with verified storage and hydrogeological conditions at the site.
