Wind effects on shallow water contaminant transport simulation

Diego Bareiro, Enrique O’Durnin, Laura Oporto, Christian Schaerer


Ypacarai lake is an important water resource with great ecological value in Paraguay. It constitutes an important natural, tourist, cultural, recreational area and plays a key role in the development of industries and agriculture. Despite of its importance, human activity and the lack of environmental regulation and management have produced a severe increase on its pollution, to levels that produces a strong degradation of its surrounding biosphere [2, 3]. Several attempts to recover the lake have failed, mainly due to the lack of complete information about its dynamic and interaction with its boundaries (including its bottom) and meteorological components (such as the wind). In this work, we analyze the influence of wind and bottom in the distribution of a contaminant discharged into the lake to identify critical regions in it.
