MORPHOMETRY OF LAKE SFANTA ANA, ROMANIA (LAKE SAINT ANN)

Lake Sfanta Ana is one of the most emblematic lacustrine complexes of our country. In this context, its monitoring is not only necessary but also compulsory. The study of its evolution and the forecasts are done easier because we have had hydrotopometric highs for about 100 years, even if the frequency of evaluations has not been periodical. The morphometric elements have had a normal evolution, of continuous diminution, specific to lacustrine complexes. The modification rates of the morphometric parameters are different, but they all highlight the necessity of taking urgent measures of protection, in order to slow down the filling speed of the lake basin. Silting is fast due to anthropic influences. The tourism activity produces, direct and indirectly, alluviums that reach inside the lake, due to the processes occurred on the slopes of the crater. We must find a modus vivendi, which is possible in theory, so that tourism and environment protection may “live together” in harmony.
