IMPLEMENTATION OF SOME CALCULATION METHODS OF THE EVAPORATION IN THE CATCHMENTS OF PRUT AND BÂRLAD RIVERS

STAN FLORENTINA, NECULAU GIANINA

ABSTRACT. Implementation of some calculation methods of the evaporation in the catchments of Prut and Bârlad rivers. Evaporation is a key element in achieving the water balance within a catchment, without which there is no possibility of making a judicious exploitation of water resources. It is important to be aware of this parameter, especially in dry periods and in those with intense vegetation, in order to estimate the necessary amount of water in atmospheric and soil drought. For this reason, the catchments of Prut and Bârlad rivers were chosen, as they are located in an area vulnerable to drought and because it is essential to know the evaporation in such a region. Obtaining the values of this parameter directly can be made in few places in the country; therefore it is imperative to use indirect methods, too. As a result, this study aimed at the estimation of the evaporation by using several calculation methods and its analysis in comparison with the values obtained directly.

Keywords: potential evaporation, areas vulnerable to drought, methods of calculation
