Cliff reconstruction at Jastrzębia Góra

The process of cliff erosion in Jastrzrtbia G6ra is a superposition of two phenomena: the abrasion at the foot of the cliff and slope failures of its upper part. Prior to the reconstruction works the stability analysis was done. Obtained results clearly documented reasons of slope failures observed during years. Based on the results five methods of slope protection were discussed The chosen method for reconstruction of a one cliffs stretch consists of a drainage system installation and slope support by means of reinforced sand blocks. During construction works the emergency laser system at the edge of the cliff was installed The construction works were successfUlly completed in the middle of November 2000.
