I divided my work into two main parts, in the first one I am describing the basic characteristic environment of area around the water basin Sĺňava and in the second part I am studying the ecosystem of the water basin. The second part of my work is described widely than the first part. Main points of second part, where I am describing the area of water basin Sĺňava are animals, plants, bacteria in ecosystem and then the influence of anthropogenic activities on the nature of Sĺňava. This two main parts are enclosed with an discussion where I am trying to determine the main negative influences at the ecosystem of water basin Sĺňava and at least shortly design some solutions how to eliminate them. At the very end of my work there are enclosed photos, pictures and maps of the area I am writing about. III. Basic characteristics of area around Pieštany

3.1 Geographical position of city Pieštany


Piešťany are situated on South-West Slovakia on opened Dudváh basin, which is nearly seven kilometers wide. They lay in the North-West promontory of Podunajská basin, they are surrounded by mountains Malé Karpaty on the West and Považský Inovec on the East. The position of the city is closely related to the river Váh. This river (the longest in Slovakia) cuts city Piešťany into two unequal parts. The smaller part, on left bank of Váh is a health resort. For long time there have been spa with healing sources of thermal mineral water. On the right bank of the river is situated city part of Piešťany. Here are shops, organizations, some of the spa and healing houses, culture buildings, parks and sport centers and private houses, where inhabitants of Piešťany live. On the South part of city is situated big water basin Sĺňava, center of water sports, favorite place for fishers, but also permanent or temporary home for birds – island Čajka (Gull). Piešťany are in height 168 meters above the sea level. 3.2 Physically- geographical characteristics

3.2.1 Relief

The east margins of the cape of Podunajská basin, where are lying Piešťany, are formed by the massive of mountains called Považský Inovec, its height is 1042 m. It begins on the south near city Hlohovec a ends on the north in Jarabské sedlo, which distances it from Strážovské mountains. Nearest to the city is Serbal’s hill, among people known as Červená veža (Red tower), known also as Škarbalová with height 268 m. above sea level. It is a cultivated forest, which forms nice area around spa and recreation center on the left bank of Váh. For the thermal mineral water sources and the chemical composition of thermal water is most important the geological building of southwest sides of Považský Inovec.
