Application of MIKE Coupled Modeling in Water Surface Profiles Calculation of Inland Waterway
[Purposes]During the process of deducing water surface profiles in inland waterways,hydrau-lic structures such as sluices often significantly impede water flow.This study aims to investigate the ap-plicability and accuracy of one-and two-dimensional coupling models incorporating hydraulic structures in solving water surface profile calculations for inland waterways.Using the Ru River as a case study,mathematical models are established to examine typical channel conditions.[Methods]Measured cross-sections of the river and innovative terrain modeling at sluice locations are utilized to develop one-and two-dimensional coupling models of the river channel.After calibrating the models,water surface profile calculations are performed for analysis.[Findings]Analysis of the flow field distribution at sluice loca-tions indicates that the simulation results accurately reflect the obstructive effects of hydraulic structures on water flow through the sluices,thereby affecting water level changes upstream and downstream of the sluices.[Conclusions]The results of the one-and two-dimensional coupling models demonstrate satis-factory calibration and applicability.The application of this method provides reference for computing wa-ter surface profiles containing hydraulic structures.
