【 摘 要 】

There is no doubt that drought is considered the second major issue humanity confronts with after of course, pollution. Due to the numerous forms it can occur and the various levels it can create damage scholars have categorized it mainly into agricultural, environmental, hydrological, meteorological and others. This designation was chosen in order to better understand and study the phenomenon`s manifestations. More than a couple of indexes have been proposed by specialists for preventing and measuring it relying mostly on: temperature, rainfall, sun shine and other features. This multitude of indexes made room for a large number of different interpretations which makes the phenomenon even more difficult to study and prevent. The seven indexes the hereby paper uses to calculate indexes are: Palfai drought index, DeMartonne index, N. Topor index, Selianinov hydrothermal index, Lang rain index and Domuta hydroheliothermal index. The case study is conducted for Lugoj for a period of 34 years (1980-2014) in this time impressive amount of data has been collected. The study revealed that the wet and dry periods of time alternate, therefore, there is no threat of aridisation or desertification in the near future.
