ABSTRACT.- A comparative analysis of the flood phaenomena occuring in the year 2005 on the Gurghiu and Răstoliţa Rivers. The average amount of rainfall to characterise the pluviometric situation of Romania in the year of 2005 was 866.5 mm/m2/year (compared to normal climatic-647.0 mm). The excess in precipitation duration and quantity during the months of January-May, July-September, December and the deficit in June, October, November, determined an annual rainfall surplus and thus creating the proper conditions for the emerging of the flood-phaenomena that was to manifest at wide scale during this year. Considering the data offered by the Mureş Water District, although in the last 40-50 years there have occured major floods in most catchment areas, never in the past 100 years, have floods lasted over a time period so vast: from (February to September) and covered an area so large as in the zear of 2005. I have chosen to study the flood phaenomena through a comparative analysis of two referencial river basins in the county of Mureş: the Gurghiu and the Răstoliţa river basins, in order to observe the difference generated by the form, slope cathegories, vegetation covering, land use, and population distribution in the process and effects of these floods.
