河口混合与泥沙输运

, 2000
根据振荡边界层理论和波流分解方法，导出了河口往复水流的流速垂向分布廓线，据此建立了河口垂向准二维水流、盐度、泥沙运动模型。对泥沙输运，完整地考虑了其对流、扩散、起动和沉降的动力学过程。模拟结果与实测资料进行了对比。应用该模型研究河口泥沙输运 ...

高立式沙障风沙流场对积沙过程的动态响应

, 2015
阻沙栅栏是一种重要的机械防沙形式，具有很好的阻沙效益，它对近地表流场和沙面蚀积过程产生了很大扰动，并导致了周边的风沙地貌的不断变化，而且风沙流场特征也随地表风沙地貌的发育而动态变化。本文通过室内风洞模拟和野外实地观测，研究了高立式尼龙网沙障前后风积地貌发育过程，分析了近地表风沙流场对沙障积沙的动态响应，探讨了高立式沙障的防护效益对积沙的变化过程。主要结论如下： （1）阻沙网积沙断面形态为单峰形，积沙主要在阻沙网的下风侧。阻沙网的积沙高度和宽度逐渐增加，积沙初期和中期峰尖窄，后期峰较宽 ...

侵蚀性降雨对黑土坡耕地土壤侵蚀特征的影响

Shuitu Baochi Xuebao
[目的] 降雨是黑土坡耕地水力侵蚀的动力来源,研究天然降雨条件下坡耕地土壤侵蚀特征对水土流失防治具有重要意义。[方法] 基于黑龙江省海伦市光荣小流域2021—2022年不同坡度(3°,5°和7°)顺坡垄作径流小区观测的43场次侵蚀性降雨事件,采用K-Mean聚类法对比分析不同雨型和坡度下径流与输沙特征,并探讨影响坡耕地径流与输沙的影响因素。[结果] 研究区以短历时、大雨强、小雨量的降雨(雨型3)为主,其次是中等历时、中等雨强、中等雨量的降雨(雨型2),长历时、小雨强、大雨量的降雨(雨型1)极少发生 ...
