Hydrological and landscape role of the small drainage basin springs located in the western part of the Łódź Upland margin zone
Languages of publication
Na podstawie przeprowadzonych obserwacji przeanalizowano położenie i morfologię nisz
źródłowych, na tle budowy geologicznej zlewni Dzierżąznej. Opierając się na wynikach
systematycznych pomiarów, obliczono również podstawowe charakterystyki wydajności źródeł,
a także dokonano próby analizy powiązań między poszczególnymi źródłami a studniami,
reprezentującymi drenowane przez nie zbiorniki wód podziemnych.
In this article the authors have represented the introductory research results of the springs
located in Dzierżązna drainage basin which touches the Grotniki-LuĆInierz sandr in the
western part of the Łódź Upland margin zone. First of all, the location of the springs, their
morphology and the output were subjected to an analysis.
The springs can be found in the erosional undercuttings located at the dry valley mouths.
They possess distinctly developed long shaped, steep scarped, 2-3 m deep spring niches with
flat, strongly waterlogged bottoms (fig. 2).
The discussion of the research material lets us state that the highest outputs and the low
variability occur in the Ciosenka river springs - the left tributary of the Dzierżązna river.
The contribution of the spring water in the total Ciosenka river runoff is about 57%. The
Dzierżązna river springs are also characterized by the low variability but their output is much
smaller (tab. l). Their contribution in the total Dzierżązna river runoff is hardly 20%.
Different hydrogeological conditions result in the output differentiation of the described springs. The ground water draining in the spring niches of the nothern direction links to general
land slope and to the aquifer horizon stratification. The surveys have revealed at least
two-level spring alimentation. The upper aquifer horizon has an unconfined table (water flows
towards outflows) and the lower one - confined table (in some springs a distinct pulsation
can be observed).
