Measurements in karstology

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

Objectives and competences

Modern karstology relies on accurate measurements of different physical and chemical parameters in karst systems. Parameters such as water discharge and level, specific electric conductivity, concentration of dyes, temperature, hydrochemical parameters etc. are nowadays continuously monitored in karst systems. Easy handling with instruments and data collection can mislead the researcher to uncritical collection and evaluation of obtained data. Students will learn principles of measurements of different quantities in karst system as well as data handling and analyses. Students will get practical experience with some of the most common instrumentation.

Prerequisites

/

Content

• Measurements of basic physical parameters
• Sensors
• Resolution, accuracy and calibration of instruments
• Measurements of the discharge and water levels
• Measurements of climatic parameters
• Measurements of chemical parameters of natural waters
• Experimental set-ups
• Data storage and transfer
• Error analysis
• Data analysis and interpretation

Intended learning outcomes

Student understands basic principles of measurements of different physical and chemical quantities important in karst studies. These includes calibration, programming and positioning of the instruments and data analyses and interpretation.
