DROUGHT AND EXTREME MOISTURE IN SMALL MOUNTAINOUS BASINS

 I. Haidu, Z. Magyari-Saska

ABSTRACT: The evaluation of meteorological drought and/or extreme moisture can be done with SPI index, which needs only the precipitation data for a studied region. Its calculus has a solid mathematical base using the Gamma distribution, a methodology which is auto adaptive in time and space, making possible to achieve meaningful comparisons even for different locations. In this research our objective was the make a characterization of the mentioned two phenomenons at yearly and for summer periods for three hydrographical basins in the Apuseni Mountains (Romania). After the first results we continued to characterize the hazard of drought and extreme moisture by determining the return period for key SPI index limits.
Keywords: SPI index, Apuseni Mountains, precipitation interpolation, fast calculus, hazard map, return period.
