SEASONAL FLOW REGIME ON THE RIVERS FROM CĂLIMANI MOUNTAINS

In this study we try to analyze some important hydrometric problems such as the seasonal river flow regime on the rivers from Căliman Mountains, regime types and regime’s space and time variation. The seasonal river flow repartition is determined by the way all supply sources combine during the entire year. In all seasons it can be observed a strong correlation between flow values and basins’ average altitude. This study uses data from 14 hydrometric stations, with rivers that belong to three different hydrographic basins: Siret River, Mureş River and Someş River. The data series analyzed in this study about river flow regime from the three basins ranges over the period 1950-2010. The availability areas for these relations reflect precise enough role of the climatic factors in the seasonal flow’s land repartition. Seasonal average flow maps highlight the contrasts between the characteristic values of the mountainous space
