ABSTRACT
Heavy industry, open-pit mining and other types of intensive human activity are affecting the surrounding landscape in many ways. The intensive mining followed by industrialization is changing the environment in large areas. It affects the global structure of the area influencing the land-use, georelief shape, settlement distribution and hydrological network structure. In this article we focus on the hydrological network reconstruction as the knowledge of the original network is important for further development of the region. The methodology is introduced on study area situated in the North-West part of the Czech Republic in the brown coal basin near the town Most. The hydrological network reconstruction is performed using the old maps of the area of interest. The old maps were selected with respect to scale and stage of landscape/industry development. The oldest used maps are the maps of the 2nd Military Survey of Habsburg Empire (ca. 1846) where is described the natural development of the contemporary agricultural land. Maps of the 3rd Military Survey of Habsburg Empire reambulated in 1938 are introducing the agricultural land being transformed into industrial landscape with chemical industry and open-pit mining. The current data are showing the industrial landscape with reclamations (former open-pit mines turned into forest, lakes, etc.) and heavy modified hydrological network. Several methods for rivernetwork development analysis are introduced including sinuosity analysis, displacement analysis, etc.
