water movement
Examples
- Experimental study on water movement of latosol under drip irrigation
滴灌条件下砖红壤水分运动试验研究 - According to the basic equation for water flow in subgrade soil , based on the basic soil properties of compacted loess , the redistribution of soil moisture and the soil water - migrate parameters are studied
摘要基于黄土路基压实后土体的基本性质，根据路基土中水分运动的基本方程，通过室内一维土柱入渗试验，得到不同压实度的黄土湿润锋湿度与平均湿度、水分入渗速率的关系曲线。 - The change of big pore section shape has more influence on soil water movement , but in small pore channels , the influence is small , in addition of pore section shape , it can get better prediction of unsaturated hydraulic conductivity
粗大孔隙通道的截面形状及变化对水分运动影响较大，较细空隙通道截面的形状对水分运动影响较小。修正孔隙截面形状对水分运动的影响，进一步考虑孔隙截面形状因子对土壤水分运动的影响，可以得到对土壤水分运动参数更正确地预测。 - On the basis of the theory about water potential in soils , a partial differential equation of water movement in unsaturated soils is derived , which chose volumetric water content as the control variable . the numerical solution of the equation using finite difference method is discussed in this paper , and the modality to calculate water movement in slope considering rain infiltration
基于非饱和土的土水势理论，本文推导了以体积含水率为因变量的二维非饱和土的水分运动方程，并给出了用有限差分法来求解此偏微分方程的方法，得到了考虑降雨入渗影响的土坡水分运动的计算程式。 - There is a period of soil contents range from ten to twenty five days over the humid discussed area in summer , and the period is not obvious at the discussed zone of close oasis desert area in summer and winter . ( 2 ) soil temperature exits several periodic variations of different depths ranging from six to twenty four days in heihe region , and nine to thirty days in gaize and shiquanhe region . it also shows that gradient of soil temperature affects on the soil content movement more greatly in summer . ( 3 ) the land surface temperature of yangtze river lower region is retrieved from noaa - ahvrr data
( 2 )根据土壤温湿资料，采用功率谱分析、 pca分析等方法，分析了两种典型下垫面土壤温度的时空分布特征及其对土壤水分运动的影响，发现研究区土壤温度除日和年变化周期外还存在6 30天的不同周期；下垫面的非均匀性及其季节变化及温度梯度变化对土壤水分运动有很大影响，冬季温度梯度变化对土壤含水量影响大于夏季温度梯度对上壤含水量变化的影响，且温度梯度与水分运动方向相反。
