Abstract: The objective of this study is to analyze the hydrological regime of the Prahova River along its Carpathian and Subcarpathian stretches. The study reach has a length of 56 km and is situated between the Prahova River source and the downstream confluence with its main left tributary, the Doftana River. The description of the hydrological regime of the Prahova River is based on the statistical analysis of the climatic and hydrological data recorded at the meteorological stations and hydrometric stations in the area of interest. In order to understand the hydrological regime of the Prahova River, we focused on the following aspects: (1) sources of supply, (2) climatic factors (temperature regime, precipitation regime), (3) the mean flow, (4) the maximum flow (floods), (5) the sediment discharge and (6) the thermal and freezing regime of the Prahova River. The importance of this study lies in the need to know the hydrological regime that plays a leading role in the study of the morphodynamics of the Prahova River channel.

Keywords: hydrological regime, statistical analysis, climatic factors, mean flow, floods, sediment discharge, hydrological nivo-pluvial regime.
