Distinct and regular diurnal fluctuations of stage and discharge have been observed in the river Suså during dry summer periods. Examples of the fluctuations are shown and some pertinent characteristics of the fluctuations are pointed out. The effect of various factors contributing to the generation of the diurnal fluctuations are discussed in this paper. It has been found that diurnal variations of the rate of evapotranspiration from riparian zones adjoining the river is the most significant single factor contributing to the fluctuations in the river. The mechanisms by which diurnal variations in the rate of evapotranspiration generate fluctuations in the river are discussed using simple qualitative models of the river-riparian zone.
