abstract:
Changes of morphometric traits in lake Piaseczno are a resultant of climatic conditions, including atmospheric precipitations, as well as activities influencing the water balance within that region. Northern part of the lake, with a slight inclination of the lake bed, is the most vulnerable to transformations, because it is strongly susceptible to fluctuations of atmospheric supply and tensions of irrigation meliorations. Dynamic changes of Piaseczno shore line have an effect on all the morphometric elements, causing serious oscillation in their values. Changes in the catchment performance are mainly associated with practical management of its natural resources. The result is reducing the woodland and peat-bog along with increase of agrocenoses and recreational areas. Despite the extensive character of those transformations due to useless agricultural and permeable soils, agriculture and then recreation are considered as the general factors affecting the lymnological status of lake Piaseczno.
