   Sammanfattning : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. LÄS MER

3. 17. Response of Bolivian Altiplano Lakes to Seasonal and Annual Climate Variations

   Författare :Ramiro Pillco; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENSO; terminal lake; bathymetry; lake level; water balance; lake routing; paleolakes; climate change; precipitation pattern; intermittent rivers.; Desaguadero River; Lake Titicaca; Lake Poopó;

   Sammanfattning : The Bolivian Altiplano is situated between two mountain ranges, the western and eastern central Andes in South America. It has two major lakes, Lake Titicaca to the north, and Lake Poopó to the south, which both are important for the nature as well as for the living conditions on the Altiplano. The two lakes are the remnants of large paleolakes. LÄS MER
