植物河道河相关系动态调整

摘要

基于前人对无植物河道河相关系研究方法及研究成果,本文遵循仙农熵(Shannon Entropy)理论,利用最大熵原理和变分法,给出考虑植物因子影响的河相关系系数动态表达式,并利用室内物理模型试验所观测的数据对该公式进行敏感性分析和验证,得到比较满意的理论结果.%Based on the previous research results of non-vegetated channels and considered the vegetations effect on the river width adjustment, this research on vegetated channels hydraulic geometry followed the Shannon's entropy theory, and used the maximum entropy principle and the variation calculus to obtain the expression of dynamic hydraulic geometry. Meanwhile, the data observed from model tests are used to analyze the sensitivity of κ value and further verify mentioned-above expressions. Finally, a satisfying theory analysis result dealt with width adjustment in vegetated channel was achieved.
