Evaluation of the quality of lentic ecosystems in Romania by a GIS based WRASTIC model

Abstract Globally, ecosystems are constantly degrading as a result of pressures derived from human activities and climate change. For working towards the restoration of the natural balance, it is necessary to evaluate the deviations induced in the ecosystems, to identify where the changes took place...
