  2. 1. Lake Hydrodynamics and Pollution Transport under Climate Change : The Case of Lake Victoria

    Author : Seema Paul; Henrik Ernstson; Zahra Kalantari; Abhijit Mukherjee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bathymetry mapping; model verification; water balance; correlation; tracer transport; wind hydrodynamics; pollution and nutrient transport; climate effect; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. READ MORE
