Research methods and techniques in karst hydrologeology

This course is part of the programme
Karstology (Third Cycle)

Objectives and competences

Student is able to use and deepen the basic knowledge about karst hydrology and specific characteristics of the structure and functioning of karst aquifers. Hydrogeological research methods are adapted to such complex structure and they are suitable for application in karst areas. They include methods which are fundamental for all hydrogeological studies (geological and geomorphological research, hydrological analysis, water balance, hydrochemistry and isotopic analysis, remote sensing, geophysics, modelling), but can be modified for the use in karst. But special emphasis is on research methods which are specific for karst aquifers. Speleological methods enable direct observation of the aquifer structure and the characteristics of groundwater flow. Especially important for the study of directions and characteristics of groundwater flow in karst is tracing with artificial and natural tracers. Student becomes familiar with the significance and development of research methods in karst. He understands the difference between the structural and functional approaches and the necessity of a simultaneous use of these two approaches and different research methods in the study of karst water systems. He knows the theoretical bases of the most important research methods and techniques. Based on the examples from practical work he is able to compare their characteristics and different ways of application.

Prerequisites

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.
