Determination of the origin of water in springs from the simultaneous application of natural and artificial isotopes. Some aspects of the origin of water in the Rashche Spring

The simultaneous application of artificial and natural isotopes to determine the origin of water in springs is described for multi-component systems. The main feature of this report is an attempt to solve the origin of water in a karstic spring, the formation of which could derive from various flows (surface and underground) arising from a large precipitation area. The isotopic distribution in the precipitates is uniform. The method is applied to the practical problem of the Rashche Spring. The water in the spring originates in the Polog region. The input-output water balance of the Rashche Spring indicates the possibility of the participation of different flows in the spring. Data from natural and artificial isotopes have been taken as a model that is acceptable for different methods of observation including hydrological aspects, which cannot be obtained by natural isotope analysis alone.
