MONITORING OF HYDROLOGICAL DROUGHT ON THE RESULTS OF LONG-TERM DATA FROM LUGANSK CENTER OF HYDROMETEOROLOGY
The paper deals with the problem of effective identification of the beginning and finishing of hydrological drought in the Lugansk region. The Standardized Precipitation Index (SPI), which is recommended by the World Meteorological Organization as a starting point for monitoring droughts, was selected as a drought indicator. To test the SPI as an indicator of hydrological drought the below water bodies were taken as the Isakovskoye reservoir and the Lugan and the Olkhovaya rivers. Based on the results of the SPI Generator application program for retrospective meteorological data from 1838 to 2021 the characteristics of previous severe and extreme droughts have been determined. For the present time, the origin and development of a severe hydrological drought has been predicted.
