Soil water content, suction and characteristic curves in the coastal watersheds of the Pearl River Delta
珠三角滨海小流域土壤水分吸力及特征曲线研究

The underlying bedrocks of Zhongshan and Zhuhai in the Pearl River Delta are mainly granite.Weathered granite soils in this region contain large proportions of gravel and grit,giving the soils a peculiar soil water characteristic curve (SWCC).This literature focused on the coastal watershed of Zhuhai City and analyzed soil texture in the watershed using Mastersizer 2000.The soils in the watershed are mainly sandy loam and loamy sand.On this basis,changes in the characteristics of the soil water content,suct...
