ABSTRACT – The triggering factors of the flood waves from the rivers in the Gilort hydrographic basin. This case study makes an analysis of the main factors responsible for the manifestation of high waters and flood waves in the area using data from the period between 1982-2007 (26 years), provided by the six hydrometric stations from the basin. Studies included maximum 24-hour rainfall, and Probable Maximum Precipitation (PMP), precipitations intensity and various parameters for the snow cover (duration, thickness, layer melting). The interpretations were made on a multi-annual, annual, seasonal or monthly scale, depending on their relevance or the method used in the study. The main conclusions were that the most significant precipitation quantities in 24 hours appear in the summer, and that the liquid precipitations in the winter are more important comparative to other regions, due to the Mediterranean influence.
