| Zusammenfassung |
| Global warming resulting from increasing
greenhouse gases in the atmosphere and the local climate changes that follow
affect local hydrospheric and biospheric environments. These include lakes that
serve surrounding populations as a fresh water resource or provide regional
navigation. Although there may well be steady water-quality alterations in the
lakes with time, many of these are very much climate-change dependent. During
cool and wet periods, there may be water-level rises that may cause economic
losses to agriculture and human activities along the lake shores. Such rises
become nuisances especially in the case of shoreline settlements and low-lying
agricultural land. Lake Van, in eastern Turkey currently faces such problems due
to water-level rises. The lake is unique for at least two reasons. First, it is
a closed basin with no natural or artificial outlet and second, its waters
contain high concentrations of soda which prevent the use of its water as a
drinking or agricultural water source. Consequently, the water level
fluctuations are entirely dependent on the natural variability of the
hydrological cycle and any climatic change affects the drainage basin. In the
past, the lake-level fluctuations appear to have been rather systematic and
unrepresentable by mathematical equations. Herein, monthly polygonal climate
diagrams are constructed to show the relation between lake level and some
meteorological variables, as indications of significant and possible climatic
changes. This procedure is applied to Lake Van, eastern Turkey, and relevant
interpretations are presented. |
