Název v původním jazyce

Changes in water temperature in selected streams of the Morava river basin

Popis výsledku v původním jazyce

Systematic records on flowing water temperature in the Czech part of the Danube River basin started in the late 19th century. However, their detailed analyses have been – even after dozens of years with operating monitoring network – performed very rarely. The aim of the present contribution is therefore to bridge this gap at least partially, and to present the most interesting results stemming from the newly conducted analysis. Series of water temperature in daily time step (represented by morning measurements) from selected water-gauging stations located in the basin of the River Danube delineated by the Morava River are examined. Attention is drawn to the possibilities of checking and extending the records, predominantly at specified times and especially in the monthly time step. Furthermore, water temperature is compared to air temperature, and the Mann–Kendall trend test and a homogeneity check are used in order to find out what types of nonstationarity may be expected relative to water temperature in the area of interest, factoring out the probable errors in the records. Based on the information gained, valuable forecasting models dealing with water temperature in the Morava River basin can be built in the future after performing further analyses recommended at the end of the contribution.
