Abstract
This study is the second year’s work of a two-year project. In the project, the influence of
Chi-chi earthquake on rainfall-runoff process in Wu-creek Watershed is studied. In this study, a
time-varying kriging was proposed to estimate the basin average precipitation and a multi-objective
model parameters auto-calibration method was developed. Then these methods are used to
estimate the basin average precipitation and to analyze the characteristics and the differences of the
rainfall-runoff process in Wu-creek watershed before and after the Chi-Chi earthquake. The result
shows that there are significant differences of the rainfall-runoff process in Wu-creek watershed
before and after the Chi-Chi earthquake. Not only the total volume of the runoff increases but also
the time to peak is advanced. The research centers and hydrological engineering departments can
also use the achievement of this study to improve the simulation the rainfall-runoff process in
Wu-creek watershed.
