A Study of the Effect of Yiluo River on the Flow and Sediment of the Yellow River
According to Xiaolangdi,Huayuankou and Heishiguan Hydrologic Station of measured net flow and sediment transport data in recent 50 years, cross wavelet analysis method, combined with cross wavelet energy spectrum,wavelet spectrum and wavelet power spectrum to investigate the impact of exchange rate to the river Yiluo sediment into the Yellow River of water and sand.The results show that Heishiguan and Xiaolangdi Dam had 4~9 years'' scale periods in 1978-1992.Dam sediment did not related.Heishiguan runoff has the strongest effect on Huayuankou which are mainly concentrated in the main period of 0~9 years in 1965-1996, Heishiguan has a sustained, stable effect on Huayuankou bore flow.Heishiguan sediment runoff has the strongest effect on Huanyuankou which are mainly concentrated in the main period of 4~10 years in 1958-1970 and 0~6 years in 1956-1962, Heishiguan sediment has a certain effect on Huayuankou, but the overall impact is not.Yiluo River runoff inflow has a significant effect on the Yellow River, but the sediment has the little impact on the Yellow River.
