VARIANT SELECTION OF WETLAND AREAS RESTORATION IN THE KAMPINOS NATIONAL PARK BASED ON HYDRODYNAMIC MODELLING RESEARCH
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 451, Issue 451
Abstract
Modelling research was conducted in the hydrogeological valley unit, where the Kampinos National Park (KNP) is situated. The aim of the calculations was to provide a prognosis for the evaluation of proposed restoration variants of the wetland areas located in the KNP. Implementation of the research task required simulation of threats connected with the present hydrographic net transformation. The analysis of particular variants of hydrographic net transformation revealed that the most effective, in terms of groundwater level increase, would be complete elimination of the melioration net, whose base element is the Lasica Canal. The calculation results indicate that the change of hydrodynamic state, as a result of change in the Lasica Canal course, will be less significant than its total elimination. In the first period, after restoration of the meander character of the riverbed, an undesirable groundwater level decrease can appear as a result of decrease in riverbed resistance. As the riverbed colmatage increases in time, the groundwater table levels will be rebuilt or even will locally exceed the present states.
