POLYACRYLAMIDE EFFECT ON SEDIMENT YIELD, RUNOFF, AND

Polyacrylamide effect on sediment yield, runoff, and seedling emergence on a steep slope K. Chaudhari and D.C. Flanagan Introduction Recent estimates indicate that 600 000 ha of land surface is critically disturbed annually in the United States by construction of new urban areas, roads, and highways (Troeh et al., 1991).

Effect of Polyacrylamide Application on Runoff, Erosion

Effect of polyacrylamide application on runoff, erosion, and soil nutrient loss under simulated rainfall. Pedosphere. 21(5): 628–638. INTRODUCTION Soil nutrients following rainfall can be lost by sur- face runoff and/or vertical percolating water in a dis- solved form and with the eroded soil particles in an adsorbed form.

Effect of polyacrylamide and gypsum on surface runoff

Research highlights Crop cultivation, being done on highly sloped lands in hilly areas in Indian Himalayan regions, causes considerable sediment and nutrient losses along with runoff. This paper is intended to show the extent of losses without any conservation measures, and indicates the effect of soil conditioners like PAM, gypsum and their combination to be applied for reducing these losses.

Effect of Polyacrylamide Applications on Soil Hydraulic

Generally, when PAMR increased, the total runoff, the total sediment mass, the maximal sediment concentration in runoff and the maximal sediment intensity all decreased. This implied that PAM applications to a fraction of the soil surface could reduce erosion from sloping land. The larger the PAMR, the smaller the runoff and the sediment yield. 5.

Several studies on metal removal from real contaminated waters using biosorption technique evolved in recent years. Table 1 summarizes the important results of the studies associated with the application of biosorption for the treatment of real metal-bearing wastewaters. Even though some results were far from perfect, biosorption showed potential to remove metal ions from complex effluents.
