authorities in their mandatory monitoring and reporting obligations regarding data emissions to the surface water WEISS briefly stated (1) 2010LIFE presentation51 Slide 52 The project will integrate the data to be collected in the framework of these reporting tasks; Remaining knowledge gaps, with respect to pollutant types will be filled; Problems concerning appropriate spatial scales, temporal scales and emission thresholds enabling advanced analyses will be addressed. WEISS briefly stated (2) 2010LIFE presentation52 Slide 53 WEISS does NOT: Involve water quality modelling in the water bodies itself; Model physical or chemical transformation of pollutants dissolved in water while transported; Model seasonal variations in the emissions, their transport, and accounting.
