Response of Low Flows of Polish Rivers to Climate Change in 1987–1989
The paper discusses changes in the low-flow regime of rivers in Poland, resulting from climate change that occurred between 1987 and 1989. The low-flow variability of rivers was measured with the use of the number of days with low flows (ND LF ) below a threshold value, which was adopted as the 0.1...
