This project is the first research activity that implies field studies for investigating the mechanisms that generate orthotidal rivers. The research team is investigating termal waters in karst areas. Tidal signals are expected to be found in thermal karst springs and rivers. The following water parameters are measured: level/discharge, temperature and electrical conductivity. Air temperature, relative humidity and pressure are also measured in order to observe the influence of the atmosphere on the studied water parameters.
The study areas of this project are located in Romania in 5 distinct regions: Baile Felix-1 Mai, Moneasa, Geoagiu-Bai, Baile Herculane and Harsova. Each region consists of one or more areas where potentially useful thermal, cold and mixed waters were identified and are curently measured by using data loggers. Collected air and water measurement data is used for graphical and statistical analyses intended for describing the local environment (as control factor), for discovering orthotidal signals in surface waters and for proposing hypotheses explaining the generation of the detected periodic signals.
