This dissertation deals with the possibility of using water temperature as a natural tracer for a two-component drainage separation method, proposing the equation of the temperature method and determining the efficiency due to other commonly used methods. The possibility of using the separation temperature results from the knowledge that a sudden change in drainage volume is accompanied by a change in temperature. To solve all parts of this work, a collection of data on rainfall events was used in the basin areas of Kopaninský stream and Dehtaře, respectively from their sub-basins P6, KL and KP. These can be classified as small basins with an area of up to 1 km2 located in the crystalline region. The aim of the thesis was achieved by comparing individual results by separating selected methods. For this purpose, the classical statistical methods and comparative coefficients were used. One of the primary results of this work is to find out the need to specify the origin of the new outflow component in the monitored subsystems, which affects the characteristics of the used trackers. This involves a thorough knowledge of all water inlets into the runoff. On this basis the basic equations of separation according to isotopes and separation according to temperature were specified. This adjustment determines the accuracy of the resulting separation values. The following steps to compare the separation results confirmed the high success rate of separation between isotope and temperature methods. The results of the remaining methods were worse, statistically different. Itwas repeatedly confirmed that the temperature can be very successfully used as a natural tracer for drain separation, despite the restrictive conditions of use described above. For a separate use of the appropriate temperature method equation, was also determines the appropriate parameter of rainfall events, whereis expected the ability to determine the origin of new water. It was also concluded that the simultaneous use of temperature and isotopic separation can reciprocally eliminate the constraints of both methods and help to refine both methods and determine the origin of the new water.? |
