Przemiany krajobrazu w dolinie rzeki Odry we Wrocławiu związane z ochroną przed powodzią w okresie ostatnich 200 lat

The specificity of the location of Wroclaw in the valley of the Odra river and its four major tributaries (Bystrzyca, Olawa, Sleza, Widawa), distinguishes it from other towns in Poland. The hydrographical network has always heavily influenced the urban landscape, creating an indissoluble bond with him. The objective of the pursued doctoral thesis is to analyze the dynamics of landscape transformation of the Odra in Wroclaw, including the regulation of the river in the XIX century and hydrotechnical facilities, which arose after the big floods in 1903 and 1997. The collected cartographic material will be used such as topographic maps, Messtischblatter, historical town plans, and the results of their landscape research in the years 2007-2010. Spatial analysis will be carried out mainly in the CIS software, based on the developed for this purpose Spatial Information System. The paper will set out the degree of interaction: hydrotechnical development of the Odra river valley and land development in Wroctaw, and the major factors of the urban landscape changes occurring during the past 200 years will be determined.
