Tracing of karst waters
Karstology (Third Cycle)
Objectives and competences
Tracing with natural and artificial tracers is a very useful research method for the study of directions and characteristics of groundwater flow in karst. Student understands its significance for karst hydrology. He becomes familiar with the possibilities of the use of natural and artificial tracers in simple and combined tracer tests in different aquifer types. He knows how to inject the tracer, how to sample and analyse the water samples. He is able to use different qualitative and quantitative methods of interpretation of the results. He learns about different case-studies with the application of tracer tests in Slovenia and abroad.
Student can accede to an examination after reaching 50% presence at the seminar and exercises, and preparing a short written work (5 to 10 pages) treating specific topic of karst hydrology or some publication in connection with her/his seminar or doctoral work.
• Development of the method of tracing in karst
