An approach to mapping evapotranpiration by meteorological element with application to the territory of Albania

Laska Merkoci, Aferdita et al.

Evapotranspiration is one of the major problems of soil water balance Evapotranspiration. Data and Information, as an important element in the context of Spatial data Infrastructure is a question of great interest to a wide community of specialists, such as meteorologists, agronomists, hydrologists, managers of irrigation etc. Many particular researches are carried out in Albania to evaluate evapotraspiration. This paper is an attempt to introduce a general evaluation of the evapotranspiration in the Albanian territory, including the evapotranspiration regionalization. Evaluation of evapotranspiration in the Albanian territory plays a major role because Albania is a complicated and complex natural area in Europe as a result of its specific physical-geographical conditions: a mountainous region, typical Mediterranean climate, a particular hydrographical system, etc. There are various methods applied: direct measurement or observed method, indirect calculating method using empiric formulas, based on meteorological data, water balance method. It is evaluated by using multi-annual archival hydro-meteorological information of the Institute for Energy, Water and Environment, such as temperature, rainfall, solar radiation, vapor pressure, wind speed. Evotranspiration evaluation is based on the observed period of 20-30 years and 6 experimental stations GGJ with an observed period of about 10 years. Evaporation is evaluated by computing its principal components, such as: potential or reference evapotranspitarion E0, real evapotranspiration ER, evaporation deficit E, pluviometric deficit x. Evapotranspiration and territory altitude dependence subdues the vertical zonal law, having e typical regional character. Using these dependences, the evapotranspiration maps are compiled for the Albanian territory.
