土壤侵蚀的坡度影响和坡面界限

, 2000
在运动波理论基础上,就影响土壤侵蚀的主要因素,包括降雨超渗净雨量,坡面流水深、流速和切应力,以及土壤抗冲蚀能力等随坡度的变化关系进行了理论分析。并进一步对坡面土壤侵蚀的坡度界限做了较细致分析,表明坡度界限是一个变量,随颗粒粒经、容重、坡面糙率、径流长度、降雨入渗差值(净雨量),以及土壤摩擦系数等因素的不同而改变,给出了界限坡度的变化规律,并得出一般情况下土壤侵蚀的坡度界限值应在45°～48 ...

基于抛物型缓坡方程模拟近岸波流场

, 2006
波浪向近岸传播的过程中由波浪破碎等效应所形成的近岸波流场是近岸缓坡区域重要的环境动力因素之一。本文基于近岸波浪传播的缓坡模型对近岸波浪场及近岸波浪斜向入射破碎后所产生的沿岸波流场进行了数值模拟。考虑到波浪向近岸传播中局部复杂区域波向不易确定，计算时直接从波浪辐射应力定义出发。采用抛物型缓坡方程所给出的辐射应力公式来计算波浪产生的辐射应力，在此基础上耦合近岸波流场数学模型对近岸波浪破碎形成的波流场进行了数值模拟研究 ...
