Abstract
To study the effect of variation in forest cover on the homogeneity of floods, data from 23 stations, each with a drainage area less than 1500 km 2, in the Changbaishan region in China were analyzed and compared. Some of the drainage areas are heavily wooded and some have almost no woods. The data series of these stations contain almost 30 years of record from 1960s to 1980s. The observed data clearly show the runoff characteristics of both wooded and unwooded areas. With equal rainfall amounts, the peak flows from the wooded areas are lower than those from the unwooded areas. It is shown in the calculation, that if the effect of the variation in forest cover on floods is not considered in dealing with the earlier historic floods, which occurred when the area had better forest cover, the mixed-sample design flood, used for the now unforested area, would be on the low side.
