Watershed Description:1,680 km^2 Vantaanjoki in southern Finland; model testing was performed at the following gauging sites: Hanala (295 km^2 subwatershed), Sandbacka (subwatershed size not given), and Oulunkyl√§ (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 (Oulunkyl√§) 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 Oulunkyl√§). 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.
