The aim of the construction is the creation of a blind arm with the modification of the inlet, the creation of pools and landscaping on the land of the investor. The pool and shoulder will serve to retain water in the landscape and as a habitat for water-bound organisms. The establishment of pools and shoulders will extend the length - the runoff path and thus the greater water retention in the landscape. The creation of pools promotes a good environment for plants and animals and enriches the surface water reserves in the area – creating suitable niches for water-related organisms.
