An attempt to classify groundwater level depth in pine forest stands on fresh sites

The aim of the research described in this paper is to classify groundwaterlevel patterns in pine stands of forest fresh sites. The approach has been employedwith the view to facilitate explaining interactions between physiographic characteristicsand groundwater dynamics in prospective research. The methods whichhave been employed so far for explanation of groundwater level dynamics interactionswith local physiographic conditions do not let to draw firm conclusions. Theclassification of groundwater dynamics patterns requires employing more sophisticatedmethods, because of a relatively extensive range of groundwater dynamicssite-to-site variability expressed, e.g., by amplitude and cycle period. The methodsof groundwater patterns classification proposed in the literature focused either onhydrogeological criteria or, if related to forest ecosystems, focused on water balanceelements in forest habitats.The area selected for investigation represented typical features for theNorthern European Lowland forests defined by soil and form of terrain patternshaped by the last glacial period (Vistulian glaciation) and dominant share of ScotsPine (Pinus sylvestris L.) in stand species composition. The research period coveredthe 2002-2007 hydrological years. The measurement used in analysis covered35 sites equipped with measurement wells. ...
