微咸水入渗条件下的Green－Ampt模型
Green-Ampt Model of Saline Water Infiltration
摘要
Abstract
The impact on the infiltration of soil structure changes after saline water infiltration was attributed the results which were caused by generalized saturated zone hydraulic conductivity and the suction at the wetting front comprehensive changes with salinity and sodium adsorp-tion ratio. The functional relationship between generalized saturated zone hydraulic conductivity and the suction at the wetting front and salini-ty and sodium adsorption ratio under the test area water quality and soil conditions was established by using experimental data. Green-Ampt model saline water infiltration integrated into water quality factors was established and verified. Two sets of data validation results show that the errors between the calculated infiltration rate and measured values are 2. 68% and 0. 72%. Validation results show high accuracy.关键词
