Impact of hydrometeorological conditions on the chemical composition of water in closed-basin kettle ponds: a comparative study of two postglacial areas
Maciej Major , Roman Cieśliński
AbstractBasins without outlets are natural storage reservoirs that can hold rainwater surpluses in acatchment for a time. In Poland, they have been an object of detailed fieldwork in the upperParsęta and Potok Oliwski catchments, where they occupy a substantial proportion of the area.It was found that the prevailing weather conditions had a notable effect on the chemical compositionof the surface water in the kettle ponds examined. The basic method of indoor work wasan analysis of topographic maps and the statistical processing of the material collected. Thefieldwork included a cycle of measurements in the hydrological years 2006 and 2007 and for 8kettle ponds in the upper Potok Oliwski catchment. Hydrochemical mapping was carried out for20 kettle ponds located in two subcatchments of the upper Parsęta catchment and for 8 kettleponds in the upper Potok Oliwski catchment. Ion concentrations in surface water were determinedwith the help of analytic methods complying with the ISO and EPA standards. On the basisof the results obtained for those two geographically and hydrographically distinct catchments,great hydrochemical diversity was recorded, visible not only in a wide range of ion concentrationsor such indices as specific electrolytic conductivity and pH, but also in the hydrogeochemicaltypes found among the surface waters of individual basins. Because of their isolation fromthe horizontal inflow, the chief cause of the chemical differences in their waters is the verticalexchange.
