| Abstract: | Precipitation,evaporation,soil water storage and melt water are input values in the forecast model of watershed runoff yields,their observation accuracy and forecast period directly determine the forecast accuracy and forecast period.The application of 3S technology in the observation methods of precipitation,evaporation,soil water storage and melt water of watersheds are illustrated,and advantages and application prospect of 3S are analyzed in the application process comparing with the traditional method. |
