| Zusammenfassung |
| This study is the first attempt in the literature on the subject of
comparing water balance components for floodplain lake basins, depending on
the type of a lake connection to the parent river. Research was carried out
in the Bug River valley in 2007–2011 water years. Four types of connections
were distinguished in the area under study. Simple water balance equation
could only be used with regard to the lakes connected to the main river via
the upstream crevasses. Detailed and individual water balance equations were
developed with reference to the other types of lakes. Water gains and losses
varied significantly in the lakes under study. Values of horizontal water
balance components (inflow and outflow) of the floodplain lake in Wola
Uhruska considerably prevailed over the vertical ones (precipitation and
evaporation). Inflow of the Bug River waters was diverse during the time
period under study and amounted from 600 000 to 2 200 000 m3 yr−1.
Volumes of precipitation and evaporation were rather
stable and amounted to approx. 30 000 m3 yr−1. The lowest
disparity between horizontal and vertical water balance components was
observed in the inter-levee lake. Both upstream inflow of rivers water and
outflow from the lake (ranged from 0 in 2008 to 35 000 m3 yr−1 in
2009) were usually an order of magnitude higher than precipitation and
evaporation from the lake surface (700–800 m3 yr−1). Study showed
that the values and the proportion between aforementioned vertical and
horizontal water balance elements were determined by the type of a lake
connection to the Bug River. Storage volume showed no relationship to the
type of connection, but resulted from individual features of the lakes
(location within the valley, precipitation and evaporation volume,
difference between water inflow and outflow). |
