淡水与微咸水入渗特性对比分析（Infiltration Characteristic Contrast Analysis of Fresh Water and Saline Water）
微咸水 淡水 间歇入渗 连续入渗
2010/12/29
为了研究淡水与微咸水连续和间歇入渗特性的差异，采用矿化度1.33g/L的淡水与矿化度3g/L的微咸水，在黏质土壤条件下进行了一维积水连续入渗及间歇入渗试验。研究结果表明，采用微咸水入渗可以改变土壤的结构特性，从而增大土壤的入渗能力；利用一维代数入渗模型对试验资料进行处理，结果表明模型可以比较精确地描述微咸水入渗过程；入渗水为淡水时，间歇入渗减渗，而入渗水为微咸水时，间歇入渗增渗；间歇入渗的循环...
