Project summary
The Gorge was formed by deep erosion activity
of the Haluzice Stream. In the upper part on dolomite-limestone flysch bedrock, erosion gradually excavated
a 30 m deep, and a 100 m wide gorge, mostly without vegetation that gradually expanded. Due to weather
conditions, fine sandy material from the steep sidewalls eroded and formed embankment cones on the foot of
the gorge walls. Heavier surges of water transported material to lower parts where the debris created silt that
clogged fertile land in the village Štvrtok and retroactive erosion threatened the Haluzice part of the village.
On the slopes, ridges and ditches were formed that created new gorges.
The Haluzice Gorge belongs to Haluzice Village Cadastre, Nové Mesto nad Váhom District, and Trenčiansky Region in the Western Slovakia. It has a total area of 3.5 hectares. The project included comprehensive technical measures comprising stonewall weirs and stone steps. It also included non-technical measures, including horizontal barriers made of wood sill to slow water flow, and tree and shrubs planting on terraces reinforced by baskets made of willow tree to reduce soil erosion. Forest trail Haluzice Gorge was opened in 2011 with several information panels. In addition, Lesy SR incorporated Haluzice Gorge in its network of significant forest areas. These are monuments connected with the history of forestry in Slovakia in terms of natural, construction, technical and artistic values.
The technical and non-technical measures constructed in the Haluzice Gorge have multiple purposes, ranging from flood protection, water retention during dry periods, soil erosion reduction, forest ecosystem protection, protection of cultural heritage, and local pathways for education and recreation. Weirs and stone steps retain silt, caused by erosion in the upper part of the steam, as well as store high water levels during storms and slow runoff and safely drain water.
The complex stabilisation system comprised of 8 stonewall weirs, and 17 stone steps in the lower part of the Gorge. The slopes were stabilised by afforestation through terraces reinforced by willow fences. Shrubs, trees and creeper plants were planted on the floor, on the sides and on bare spots. During the following years, trees, shrubs and creepers gradually filled the whole surface of the Gorge. The last 4 m high weir was constructed towards the end in order to stop erosion and protect Haluzice Village, as well as a connecting local road with Štvrtok Village. Total length of modified Haluzický Stream included in the Gorge is 1.5 km. Currently, there are 6 functional weirs in the Gorge on the Haluzický Stream, 4 are in the right side arm. The purpose of the weirs is to retain silt, caused by erosion in the upper part of the steam, as well as retain the high water levels during storms. In addition, 17 stone steps slow runoff and safely drain water.
