Evaluation of Flood Impact of Waterway Project Based on One-Dimensional Hydrodynamic Model ——A Case Study of 2000-ton Laibin-Guiping Waterway Project of Datengxia Gorge
Published 2023-01-01“…A one-dimensional hydrodynamic model is used to accurately and systematically evaluate the flood impact of the 2000-ton waterway project with a total length of 193.876 km from Laibin to Guiping.The model is calibrated and validated,and the changes in the water level of the channel are observed.On this basis,this study analyzes and evaluates the impact of waterway regulation and construction on the channel flood discharge,hydrological station observation,bridge operation,water intake,and other aspects.The results show that the project implementation leads to a drop in the water level in the project section,which has an adverse effect on the water level observation scheme of the hydrological station.Hence,it is necessary to take corresponding remedial measures such as supplementary monitoring.Moreover,the result indicates that it has no adverse impact on bridges,water intakes,flood discharge and drainage,and irrigation.The assessment results can provide a rich and detailed basis for the approval and management of the water administration department.…”

SPBO-ANFIS Model of Combined Monthly Runoff Forecasting Based on Singular Spectrum Analysis
Published 2022-01-01“…In view of the multi-scale non-stationarity and other characteristics of monthly runoff in hydrological time series,this paper proposes a singular spectrum decomposition (SSD)-based model of combined monthly runoff forecasting that integrates the student psychology based optimization (SPBO) algorithm with the adaptive network based fuzzy inference system (ANFIS),namely the SSD-SPBO-ANFIS model.This model is then applied to the monthly runoff forecasting at a hydrological station in Yunnan Province.Specifically,time series data of sample monthly runoff are decomposed into various independent sub-series components through SSD to reduce the complexity of the time series data;then,the principle of the SPBO algorithm is outlined,and eight standard functions are selected for simulation verification and comparison of the SPBO algorithm;finally,the SPBO algorithm is employed to optimize the ANFIS condition and conclusion parameters.The SSD-SPBO-ANFIS model is built to forecast each sub-series,which is then superimposed to obtain the final monthly runoff forecasting result.In addition,the results of the proposed model are compared with those of the ensemble empirical mode decomposition (EEMD)-based EEMD-SPBO-ANFIS model and the SPBO-ANFIS model without decomposition.The following observations can be made from the results:The SPBO algorithm has favorable optimization accuracy;with a mean absolute percentage error of 5.57%,a mean absolute error of 0.20 m<sup>3</sup>/s,a Nash coefficient of 0.994 8,and a pass rate of 96.7%,the SSD-SPBO-ANFIS model has an effect better than that of the EEMD-SPBO-ANFIS model and far better than that of the SPBO-ANFIS model in forecasting sample monthly runoff.The proposed model and method can provide references for related research on hydrological time series forecasting.…”

Research on River Health Assessment of Hanjiang River Basin
Published 2023-01-01“…Health assessment of rivers and lakes is an important means of their health management.To meet the requirements of ecological civilization construction and river chief system in the new circumstances,this paper performs the classified assessment and comprehensive evaluation of the Hanjiang River Basin from five aspects:hydrological integrity,morphological and structural integrity,chemical integrity,biological integrity,and the sustainability of social service function according to the relevant methods in the Technical Guidelines for River and Lake Health Assessment (SL/T 793—2020).The assessment results show that the Hanjiang River Basin is in a state of health overall,and the score of the main stream of the Hanjiang River is slightly higher than that of its tributaries.The hydrological integrity and biological integrity of the sub-criterion layer are weak,which leads to the ecological conditions in a state ranging from sub-health to health.The social service function of the sub-criterion layer is sustainable,and the functional status is in the state of health.The health assessment of rivers and lakes in the Hanjiang River Basin is of great significance to promote its water resources protection and water environment management and ensure the sustainable utilization of its water resources.…”
