Abstract. - The excess of humidity and its associated risks in the Reghin Hills. Through its persistence, the excess of humidity can produce a series of natural risks, such as geomorphological, pedological, hydrological and also ecological, each category having a negative impact on the social and economical life.In this paper the focus relies on the analysis of the rain-fall conditions of the Reghin Hills, with a special view on the periods of excess of humidity. For such a purpose we realized an analysis of the main parameters which define the excess of humidity (annual, season and monthly variations in the quantity of rain-fall, the degree of insurance in the different quantities of rain-fall), having as a basis the data recorded between 1978-2008 in the Târgu-Mureş, Eremitu and Gurghiu stations. The establishing of the rain-fall nature for each year, season and month was realized by counting the Standardized Rain-Fall Anomaly.
Keywords: rainfall quantity, humidity excess, natural risks, vulnerability.
