  • Correlating specific conductivity with total hardness in limestone and dolomite karst waters
  • Carbonate dissolution ; Carbonate rock ; Hydrochemistry ; Karst ; Pennsylvania ; United States of America ; Water
  • The aim of this paper is to show how specific conductivity (SpC) measurements can further differentiate quantities of dissolved solids within carbonate karst areas, and thus help to suggest the natural evolutionary paths of the waters conveying them
  • . In densely populated, farmed or industrialized, regions many waters are now polluted. The conductivity meter can help to detect them; apart from the practical utility of such detection, this avoids distorsion that will result from their incorporation

  • The aims of this review are to identify the dominant morphodynamic processes governing intertidal bar systems and provide a conceptual framework with which these bars can be further investigated. It is the dominant importance of tidal water level
  • variations and wave processes in shallow water depths (swash and surf zone bores), rather than wave height variability and deeper water wave processes (breaking and shoaling waves), that constitutes the main difference between intertidal and subtidal bar

  • and its water flows along an artificial canal. The system of canal could be modified using the sustainable methods to restore some natural functions of a stream such as water retaining and self-purifying function. Groundwater and biodiversity would benefit
