Abstract

This region lays over the western part of Maramureşului and Bucovinei Carpathians, known also as the Northern Group of the Oriental Carpathians, with climatic and morphologic particularities that strongly reflect itself into the flowing regime of small rivers. To work out this study there have been elaborated and interpreted data from 16 representative hydrometric stations from the region in study, monitoring the water flow from hydrographic basins with small surfaces, which reflect more closely the local particularities of the river water regime from the surface in study. There have been taken into account the period 1968-20005, which allowed valorizing data came from the hydrometric stations. It’s been observed that the rhythmical structure of the water regime reflects the local features of supply sources, relief’s geological, morphological and morphometrical conditions. Most of the hydrometric stations present a decreasing or stationary flow trend in all seasons. Seasonal flow frequency shows a strong differentiation between poor and rich flow periods, the same thing that happens for the floods analyze. Variation coefficients group themselves after seasons. Also, the monthly flow characteristics group themselves, especially after variation coefficients.
