摘要：Changes in climatic conditions in the world often affect the
variability of water relations and soil erosion. Observed phenomena lead to
removal of the most valuable soil surface layer from slopes, washout of
minerals, deterioration of slope structure and also destruction of protective
vegetation. Geotextiles are used to protect slopes from effects of erosion.
Depending on the type of used raw material as well as production
technology, geotextiles are used for long-term or temporary protection
(biodegradable). Biodegradable geotextiles under influence of atmospheric
factors undergo gradual decomposition. The substances released as a result
of decomposition cause soil fertilization, which promotes development of
protective vegetation. The aim of the research is to assess impact of
exploitation time on selected physical, mechanical and hydraulic properties
of innovative geotextiles in form of meandrically arranged Kemafil ropes
made of wool and recycled fibers installed on slope in Jasienica Economic
Zone in Międzyrzecze. The research was carried out in the Laboratory of
Geosynthetics and Textile Products of the University of Bielsko-Biala in
accordance with the applicable European standards. Nonwovens used for
production of geotextiles were tested before installation, as well as after
6 and 12 months from their installation. Geotextiles reduce speed of
rainwater flowing down from the surface of slope and store its excess.
Waste raw materials used for production of geotextiles enable products
effectively protecting slope against water erosion.
