ASPECTS REGARDING THE VARIABILITY OF THE LEVELS OF SIUTGHIOL AND TĂBĂCĂRIE LAKES
Journal Title: Present Environment and Sustainable Development - Year 2011, Vol 5, Issue 1
Abstract
The present paper presents some issues regarding the variability of Siutghiol and Tăbăcărie lakes levels and some natural and anthropic factors which can influence this variability. The analysis is based on the processing of monthly and yearly levels of Siutghiol Lake (between 1988-2008) and Tăbăcărie Lake (between 1993-2008), taken from the National Institute of Hydrology and Water Management. The analysis regarding the variability of the levels of Siutghiol Lake highlights one interval with low levels (1990) and two years (1997 and 1999) with high levels. In the case of Tăbăcărie Lake, the analysis highlights two years with lower levels (1997 and 2004) and two years with higher levels between the years 2001-2002. The levels with the highest frequency for Siutghiol Lake ranged between 180-199 cm, which represented 28.17%, almost 71 months. In the case of Tăbăcărie Lake, the levels with the highest frequency ranged between 140-159 cm, which represented 44.23%, almost 80 months. The variation of the levels of Siutghiol and Tăbăcărie lakes is the result of the combination between the natural and anthropic factors. So, it is a connection between the mean yearly levels of the Siutghiol Lake and the annual amounts of the precipitations and also, between the mean monthly multiannual levels of the Tăbăcărie Lake and the mean multiannual monthly values of the potential evapotranspiration. The analysis regarding the correlations between the mean monthly levels of Siutghiol and Tăbăcărie lakes highlights a connection between these two lakes only in May.
