It will facilitate data selection for modeling if the effect of watershed scale can be quantitatively described. This paper aims at investigating the variations of simulated differences between different soil data across a series of water routing areas. The study was conducted using soil and water assessment tool, with the 1:24,000 SSURGO soil data and digital soil mapping data from Soil Land Inference Model (SoLIM) at 10m resolution as different input data, to investigate the stream flow differences arising from different soil data at Brewery Creek, Dane county, Wisconsin of the USA. Results show the low consistency of simulated stream flow between the two soil data at small water routing areas, but the consistency generally rises with the increase of routing area. Simulated stream flow based on SSURGO and SoLIM becomes similar especially for area larger than 10 km2. Based on the effects of continuous routing scales on simulated stream flow differences between different soil data, a preliminary conclusion can be made that coarser input data can also be used for a larger watershed for stream flow simulation. %U https://www.progressingeography.com/EN/10.11820/dlkxjz.2011.01.010
