支流入汇对干流航道影响分析

以牡丹江入汇松花江为例，利用实测资料对干支流交汇河段进行分析，为支流入汇对干流的影响提供了一些定量关系。并且从水力学伯努利方程出发，探讨了支流入汇对干流的影响，得出了在不同汇流比条件下干流水位变化规律。  

航道整治与疏浚课程建设的实践与探索

专业课程建设应以建立一个与课程体系改革相协调，与专业发展相融合的新体系为目标。课程建设首先应考虑课程宏观定位问题，在此基础上抓好教学大纲、教材、师资队伍建设。此外，课程建设的过程又是实现规范教学的过程，要重视教学手段开发和研究，改革实践环节，完善考核办法。  

江苏省内河航道低碳养护模式探讨

文章根据国际标准对低碳概念的定义，研究航道养护低碳模式的概念，分析航道养护低碳模式的内涵。从技术层面和管理层面，提出日常养护观测、航标及标志标牌的低碳养护模式，基于碳排放模型测算各种模式的碳排放量。结果表明，引入低碳模式后，日常养护观测和航标及标志标牌养护的碳排放均明显减少。通过理念创新、技术改进等，将传统的航道养护方式转变为低碳方式，有助于减少航道养护的碳排放量，有利于建设生态低碳型航道。  

Hydraulic Geometry Relation for Navigable Canals Considering Ship Speed

Definition of hydraulic geometry of navigable canals and its expression are studied in this paper.The hydrodynamic and morphologic characteristics of navigable canals are analyzed on the basis of the data collected from field surveys conducted at two segments of the Grand Canal in Jiangsu Province,China.The channel morphologic factor and the ship hydrodynamic factor are adopted to describe the hydraulic geometry relation of navigable canals.The correlation analysis shows that the ship hydrodynamics can be a dominant factor influencing the channel evolution with larger determination coefficient.Furthermore,the undetermined index in the proposed hydraulic geometry relation is also discussed,which indicates that the index related to the intensity of water flow(qualitatively reflected by the integrated ship flow intensity)is within a range of 0.5 to 1.0.
