Watershed Description: | 39.5 ha FD-36 upland watershed, located in Valley and Ridge Province in east central Pennsylvania, U.S. |
Calibration Summary: | Daily 1997-2000 E = 0.62 ---------------------------- range of 16 different seasonal daily E values (winter, spring, summer, & fall): -.40 - .88 (13 > .51) |
Validation Summary: | |
General Comments: | SWAT performed better than SMDR model on daily basis; E? = .62 for SWAT versus .33 for SMDR. SWAT was also more consistent on a seasonal basis. Authors comment that SWAT does not route runoff over landscapes to water bodeies, which is a key gap for P transport depiction. |
