Water and air measurements were conducted in river valleys of Romania to detect the shapes of diurnal profiles and their spatial variations. The studied river water parameters are pressure/level, temperature, and electrical conductivity. The air parameters, used for understanding the diurnal water profiles are pressure, temperature and relative humidity. Time intervals used in this study vary from few weeks to few months and sites are grouped depending on common time intervals for comparison purposes. The selected water monitoring sites have similar diurnal shapes of the studied parameters in areas with the natural flow (afternoon maximum water level and temperature and minimum electrical conductivity; the opposite events occur early in the morning) and disturbed evolutions in areas where dams and hydroelectric plants exist. The natural particular monitoring sites characteristics can also significantly impact the results of measurements. The mean diurnal water profiles, obtained from detrended time series, can be used for theoretical models.
