In this paper are the results of the research of the stationarity of the seasonal (spring, summer, autumn, winter) hydrological and meteorological observations data and changes at time their average values in the Rika River Basin for all period of observation. The stationarity of the hydrometeorological characteristics was researched by estimation of the significance of the trends at 5% level of the significance. The total and diference-integral curves were analyzed.
