Water – soil – air temperature relationships in the Jalovecky creek catchment

Summary

The first part of this paper is devoted to relationships between water and soil temperatures, as well as between water and air temperatures in the Jalovecky creek catchment (the Western Tatra Mountains, Slovakia). For hydrological years 2007–2008 the mean annual water temperature at Jalovecky creek, Ondrasova (559 m a.s.l) was 6.7 °C, mean annual air temperature 7.9 °C at the meteorological station Ondrasova and mean annual soil temperatures 9.4–9.7 °C at depths 5–100 cm . The maximum water temperature for the observation period of 20.1 °C was measured on 3 July 2008 at 4 p.m. in the Jalovecky creek. The linear regression and logistic Mohseni models were established between the daily minimum and maximum water temperatures and soil and air temperatures. The second part of paper is devoted to determination of altitude gradient of water temperature in the Jalovecky creek catchment, was -0.3 °C per 100 m in November 2009.
