(2)we get the map of water with different sediment levels by extracting water, creating a map with 0/1 encoding,masking and acquiring a map of SI=(TM2+TM3)/(TM2/TM3);
Pollution of Mercury, Copper and Lead in Sediment of Guangzhou Reach of Pearl River and Its Relationship with Accumulation of Organic Matter and Sulphide
The variables studied were transport of sand, underlying surface roughness, windblown sediment, wind-sand flow structure, soil mechanical composition and amount of wind erosion.
At a height of 0-20 cm, the height increased while the sediment discharge percent of sand flux decreased; there were significant differences in the sand flow formation under different land-use types.
At the same time, better correlative relationship between runoff and sediment production and rainfall and rainfall intensity were testified by multiple regression, but the correlation decreased gradually with the increase of canopy density of forest.
