Watershed Description:1,680 km^2 Vantaanjoki River, which drains to the Baltic Sea in southern Finland. [Model testing was performed at the following gauging sites: Hanala (295 km^2 subwatershed), Sandbacka (subwatershed size not given), and Oulunkylä (outlet of entire watershed] 
Calibration Summary:daily (1983 - April 1985; at Hanala): streamflow E = .81 total N E = .59 total P E = .74 
Validation Summary:daily/monthly (Hanala) E values (daily: 1989-93; monthly: 1989-97: streamflow = .57/.75 total N = .43/.10 total P = .54/.63 ----------------------------daily/monthly (Sandbacka) E values (daily: 1989-93; monthly: 1989-95: streamflow = .58/ .81 ----------------------------daily/monthly (Oulunkylä) E values (daily: 1989-93; monthly: 1989-97): streamflow = .66/ .76 total N = .51/.30 total P = .44/.64 
General Comments:Calibration and validation were performed with SWAT 99.2 primarily for a subwatershed that drains to the Hanala gauge site. Further validation was performed for another subwatershed that drains to a guage at Sandbacka, and for the entire watershed (outlet at Oulunkylä). Graphical results are also shown. The diffuse (nonpoint) emission (total source loadings) estimates with SWAT were compared to four statistical approaches. The SWAT results were found to be reasonable.
