Abstract: The aim of this study was to present the use of the natural elements of the relief of river valleys such as changes in the width of the valley bottom, landforms occurring in the bottom of the valley, differences in height of the valley terraces as favourable for the location of the dam partitioning the bottom of the valley and creating a water reservoir for the requirements of historic metallurgical centres. The research was carried out based on DEM analysis from LiDAR data. Features were chosen in river basins with a rich metallurgical legacy. Analysis of the location of the former ironworks was carried out using Surfer 12 software. Five centres were selected due to the fact that only these are the only centres suitable for research which have survived to this day. Using the shaded relief models and contour coloured maps absolute differences in height between valley levels and other forms of relief occurring in the valley were analyzed, as well as the distribution of individual terrain forms in the designated part of the valley and changes in the width of the valley bottom were analysed in the context of the location of former metallurgical centres. On the basis of the contours of the former water reservoir visible in the valley relief, and using a surface area measurement tool (Surfer software), the range of the area that the reservoir could cover was measured. On the basis of the results obtained, it can be seen that convenient geomorphological conditions were used for the placement of selected weirs and metallurgical ponds which facilitated the damming of the valley. Natural narrowing of the valley bottom, or dunes and hills directly adjacent to the valley floor, were utilised during the construction of the dam. The rivers on which the furnace ponds were constructed are relatively small watercourses, so the weirs created by the constructors are not impressive. Their height is generally in the range of about 2 to 3 metres and their length is from about 120 to 300 metres. Nevertheless, they were effective in allowing sufficient water retention and the creation of furnace ponds with a measured area of about 4.5 ha to about 25 ha.
