Descrição: To evaluate the performance of a computer model simulating runoff in the upper reaches of the Changjiang (Yangtze) River Basin over a relatively short time interval, including examining the applicability of the input precipitation data generated from global circulation models and satellite data, we used a spatially distributed model, HSPF with the ISLSCP precipitation data for 1987 and 1988 as input data. The Nash-Suteliffe coefficient (R2) for 5-day average stream flow was 0.94 in the calibration period and 0.95 in the verification period for the whole upper region. Moreover, the model simulated the 5-day average stream flow well in each main tributary, as shown by R super(2) values of 0.46 to 0.96, except that it underestimated the peak flow rates during the flood season over two years by up to 71% in the Tuojiang River and 61% in the Jialingjiang River. The ISLSCP precipitation tended to be more frequent and less intense than the measured precipitation. This was probably the main reason why the HSPF did no
