As part of the internship, Olga Meshcheryakova studied innovative approaches to solving environmental problems in karst areas. The methods were aimed at protecting karst landscapes, caves and aquifers from pollution.
So, within the framework of lectures, such topics as "The use of underground space for economic purposes" and "Speleology and spelestology: interaction and development of sciences were studied. Speleological and spelestological objects of world significance". As a result of joint work with the lecturer, the systematization of speleological and spelestological objects of world significance was carried out.
"During the field trip, we took water samples, measured hydrochemical and physical parameters of karst waters, and also studied surface karst forms," Olga Meshcheryakova said.
During the internship, a scientific excursion to the Karst Hydrogeology Center and the scientific laboratories of the Faculty of Geology and Mining of the University of Belgrade also took place. As Deputy Dean of the Faculty of Geology Olga Meshcheryakova and Dean of the Faculty of Geology and Mining of the University of Belgrade Biljana Abolmasov agreed to sign a memorandum of cooperation between the faculties. The document implies the implementation of educational programs for students, joint participation in international grant competitions, as well as the holding of an International karst Conference in 2024 on the basis of PSNIU.
