Celem pracy była analiza aktualnych problemów związanych z gospodarowaniem wodą na terenach polderowych, na przykładzie polderu Zagórów, w tym przede wszystkim jego wpływu na ochronę przeciwpowodziową terenów niżej położonych. Praca została wykonana na podstawie materiałów archiwalnych oraz wstępnych badań i obserwacji prowadzonych w ramach realizacji projektu badawczego dotyczącego możliwości renaturyzacji tego obszaru.
The aim of this work was to present a detailed characterization of Zagorow polder and its possible functions in flood protection. So far the polder composed the closed part of the valley Konin-Pyzdry entirely cut away from periodic of swelling of the River Warta by flood bank. The lack of the possibility of cyclical flooding on this area at a fast pace contributed to their drying. Consequently, it led to changes of water ratios as well as habitat conditions occurring in polder. In 2009, within the framework "Restoration of the river water circulation in the middle of the Warta river valley between Zagorow and Lad" made a possibility of the natural compensation for this area and controlled deluge of the polder in the case of the flood hazard in lower areas of the valley. Analyses showed, that at the moment Zagorow polder cannot be the alternative for standard flood reservoirs. However it is affecting for slowing the outflow down, improving distorted circulation of water in centre course of the River Warta caused by anthropogenic activity. Great natural values of the Konin-Pyzdry valley resulting from the fact of living on the Zagorow polder numerous kinds of the fauna, require the particular flood protection. The priority usually granted highly prized natural values often led to lack of comprehensive action allowing for the rational management of water in the valley. In this case an applying to the sensible compromise between the flood and natural environment protection is recommended. Zagorow polder as the only facility in the whole valley has his own drainage infrastructure. This area largely used by agriculture and a little populated in some proper legal acts and investment could constitute the additional component of the flood control. However, costs of the flood protection (repurchase of the earth and the structure of additional devices) should not exceed values of this facilities. - Źródło:
