摘要

In recent studies, hydrologists have employed modified tests for trend that are capable of accounting for short-term persistence, such as a lag-one autoregressive process. However, long-term persistence may influence the results as well. Therefore, prior to the detection of trends, an investigation should take place to determine whether or not a long memory process generates the series. In Czechia, it also applies for the series encompassing 7-day low flows since they reveal relatively high values of the Hurst exponent (except in the winter season). In the future, other variables corresponding to streamflow drought in Czechia (deficit volumes, duration or timing) are planned to be assessed in this manner.
