Water is essential for the health and welfare of people and its societies. Although our planet is covered with water, the actual freshwater supplies are limited. With the exponential increase in population sustainable and innovative ways of water management need to be implemented. The aim of this study was to record the hydrologic regime of the Agia Varvara stream that run though the city of Drama in Greece. Having knowledge of the hydrologic regime of the stream will also help in the science-based management of extreme hydrological phenomena such as floods, severe droughts and water pollution. To measure stream discharge measurements were taken three times a week from May 2019 until June 2019. Discharge was measured with the use of a current meter along two different cross-sections that were relatively close to each other. The width of the first cross-section was 7.2 m with higher stream flows while the second cross-section had a width of 8.5 m lower stream flows. The analysis of the results showed that stream was the lowest during the summer months, specifically from June 2018 until August 2018, as expected. The highest stream flows were during the end of the winter months but mainly with the spring months, specifically from February 2019 until the April 2019. The high flows are because of the melting snow in the surrounding mountain peaks, the greater rainfall and the rich aquifer of the area. The measurements were for relatively short time (only one year), but because they were taken quite frequently, they provide a good first perspective of the hydrologic regimes of Agia Barbara stream. Ideally, such measurements in the stream should be continued for multiple year in order to better assess the hydrologic regime. Finally using new technologies (UAVs and remote sensing) in combination with the classic methods (current meter), should help improve the accuracy but also increase the scale of the measurements and predictions in regard to future water supplies.
