Characteristic Analysis and Prediction of Rainfall and Runoff in Ankang Section of Hanjiang River Basin
Published 2021-01-01“…Accurate runoff simulation plays a very important role in the planning and management of water resources.However,traditional methods have some limitations in the simulation of runoff near peaks and abrupt points.This paper identifies the abrupt change components of rainfall and runoff in the basins above the controlled section of Ankang Hydrological Station in the Hanjiang River Basin through the Mann-Kendall test.analyzes the trend and cycle of the rainfall and runoff by R/S analysis and wavelet analysis,simulates the runoff series with the partial least squares regression (PLSR) and BP neural network-partial least squares regression (BP-PLSR),and analyzes the simulation effect of runoff near peaks and abrupt points.The results show that:The abrupt points of rainfall appear in 1973,1984 and 2002;and those of runoff appear in 1977 and 1985.The Hurst index of rainfall and runoff is close to 0,indicating that there will be an anti-continuous trend in the future.The simulation effect of BP-PLSR on runoff (RMSE=92.863,NSE=0.797) is better than PLSR (RMSE=152.182,NSE=0.456),and preprocessing the original data by BP can better avoid the over-fitting and local optimization near the abrupt points.…”

Research on Simulation Method for Incoming Flood of Tianyi Reservoir Considering the Influence of Karst Geomorphology
Published 2022-01-01“…The karst in karst areas leads to a more complex runoff formation process,and the construction of water conservancy projects has aggravated the complexity and uncertainty of the production and confluence process in the basin.On this basis,a semi-distributed incoming flood simulation model of Tianyi Reservoir in the Nanpanjiang River was built by the Xin'anjiang model for karst geomorphology,considering the influence of upstream karst geomorphology.The results reveal that:① the built Xin'anjiang model for karst geomorphology can well simulate the incoming flood process of Tianyi Reservoir,and the simulation accuracy index of each zone is greater than that of the traditional Xin'anjiang model;② the Nash-Sutcliffe efficiency (NSE) coefficient in the series incoming flood simulation of Tianyi Reservior based on the model constructed in this paper is greater than 0.86 during both the calibration period and the validation period,and the volume error is within 12%,which indicates that the simulation results of the constructed model are good;③ the forecast accuracy is evaluated for six typical incoming floods of Tianyi Reservoir from 2018 to 2020,and the evaluation suggests that the built zonal forecast scheme meets the specification accuracy requirements.Thus,the results of the study can provide a reference for hydrological simulation in the upstream karst area of Tianyi Reservoir.…”
