  11 rainstorm events during the flood season from 1997 to 2007 at two different spatial scales in Huaibei Plain in North part of the Huaihe River basin were simulated using Xinganjiang model, and the scale effects of storm-runoff processes were analyzed.The study area is composed by two catchments with area of 0.06km2 and 1.36km2 respectively, and the small catchment is located in the large catchment.The study area is characterized with shallow groundwater depth and large drainage ditches.The groundwater flow plays a great role in the total outflow.
