Historical Changes of Hydrological Connectivity of Selected Polish Floodplain Lakes
The main ecological and hydrological features of floodplain lakes (FPL) depend on the flood pulse. Temporal variations of connectivity result from natural fluctuations in a parent river water levels. The study area was a fragment of left fraction of the Bug River valley, within a gorge‐like section between Dorohusk and Włodawa. The aim of the study was to define a duration and frequency of potamophases and limnophases of 20 FPLs, during the period 1952–2013. A large variation of limnophase frequency was observed. The most frequently occurs short (8–30 days) and medium‐length (183–365 days) limnophases. In case of potamophases the most frequent were short episodes (8–30 days). In most water bodies, a general similarity of the duration of functional periods was observed. The average ratio of the duration of both phases showed prevalence of limnophases. Generally, two factors were observed that shape variability of functional periods in the study area: quantity of water input and FPL morphometry. The lower lake volume and less stable water input, the higher variability of hydrological connectivity. Copyright © 2016 John Wiley & Sons, Ltd.
