3D rekonštrukcia zaniknutého tajchu = 3D reconstruction of the extinct water reservoir / Tomáš Hrdý, Karol Weis. -- In the past, water reservoirs used to play an important role in mining. They are artificial water tanks that gather water and serve as energy source for mining machines´ drive. There were two water reservoirs in Rudno nad Hronom community. This article deals with a virtual reconstruction of one of them. Before the reconstruction in model software, there was a field survey of the territory. After the modelling, hydrological parameters have been calculated. Because of the precautions, the data has been obtained from Air Laser Scanning (available on geoportal.sk) and processed in Surfer programme instead of field measuring. From the obtained data, 3D model of current and original state of the water reservoir was created. The volume of the tank and time needed for filling the dike was calculated from those models. After calculating the volume, it was possible to determine the speed of filling the tank with rainfall. Results has shown that the maximum volume of the tank was 73 778 m³ and its fulfilment took 118 days. The highest state of water in the dike was 12 m with its 6 m width and 101 m length. At present day when we are forced to deal with extreme weather, periods of heavy rainfall and dry seasons, water reservoirs could serve as solution for detention of water. The fact that the reservoir was functional in the past means that it could be restored. As other water reservoirs it can serve for summer swimming and development of tourism which will lead to increase of income in the community.
