2000年4月29日市水利局组织对由上海市佘山农田水利试验站承担的《上海市郊菜区入渗规律及其排水模型研究》进行了评审。该课题根据上海市郊菜区主要土质分布情况,选择不同土质的新老菜区进行人工模拟降雨入渗试验,得到各菜区实验土壤水分参数,再应用Green-Ampt.Marn-Lenson入渗模型,计算不同频率暴雨量和不同墒情下积水后入渗量、
April 29, 2000 Municipal Water Conservancy Bureau organized by Shanghai Sheshan Farmland Water Conservancy Experimental Station commitment “Shanghai suburbs vegetable zone infiltration law and drainage model research” were reviewed. Based on the distribution of the main soil in the suburbs of Shanghai, this project selected artificial rainfall infiltration experiments in the old and new vegetable areas with different soil types to get the experimental soil moisture parameters in each vegetable area, then applied the Green-Ampt.Marn-Lenson infiltration model, Calculate the different frequency of rainfall and water content after different infiltration,
