Abstract

The current study tracks the change in the maximum outflow formed in the watershed of Kardjali dam, which is among the complex and nationally significant dams in Bulgaria and is subject to annual monitoring by the Ministry of environment and waters (MOEW). The maximum runoff is an extreme hydrological phenomenon with spatio-temporal variation, the exact determination of which requires in-depth knowledge of hydrographic, climatic, soil, vegetation conditions, as well as anthropogenic factors for each individual region. Investigating it in a certain territory during the operation of hydrotechnical facilities has been a current topic in recent decades. The purpose of the present study is to track the change in the maximum runoff in Arda River catchment to Kardzhali Dam for the period 1961-2021, which also includes the period recommended by the World Meteorological Organization (1961-1990). GIS database was created as a basis for analyzing the results, containing information from the soil map of Bulgaria 1968, land cover from Corine 2012, JICA project finished in 2005. As for the estimation of the maximum runoff information array of hydrometric data observed in hydrometric station 315/61700 on Arda River and data from the operation of Kardzhali Dam has been used for the purposes of the present study. The study shows that with proper management of the reservoir, there is no danger of flooding the surrounding terrain after the dam wall. The research contributes to improving the process of monitoring on the maximum outflow to the Kardzhali Dam and supports decision-making by the responsible institutions in the management of water volumes in the dam lake cup when a high wave occurs.
