To assess which factor contributed most to speeding up soil erosion, a Spearman rank coefficient and principal components analysis were carried out.
The uptake and erosion study, the correlation coefficient (R) and the exponent (n) were used as indicators to justify drug release mechanism.
The highest surface runoff coefficient and erosion amount were found on bare land in all five rainfall regimes, and the lowest were found on grass cover.
Crystal defects, secondary hardening phase of CrN, and various crystal and amorphous forms are produced by ion implantation, and as a result, the microhardness, wear fatigue resistance, wear abrasion resistance, erosion resistance, and friction coefficient are improved.
For grass cover and litter cover plots, rainfall events of rainfall regime IV which had the longest duration, greatest depth and lowest intensity had the highest surface runoff coefficient, soil erosion amount and subsurface flow rate.
In particular, the velocity of erosion, the effective diffusion coefficient of the drug molecule in the wetted polymer, the average pore length, and the initial pore diameter are sensitive parameters, whereas the porosity and the effective diffusion coefficient of the drug in the solvent-filled pores is seen to have little influence, if any, on the release kinetics.

According to final regression coefficients, soil erosion seems to regulate nitrate distribution across the basins, because soil loss and type, rainfall intensity and topography explained around 60% of nitrate yield variance.
The major problem with wavelet shrinkage methods, as discussed, is that shrinking large coefficients entails an erosion of the spiky image features, while shrinking small coefficients towards zero yields Gibbs-like oscillation in the vicinity of edges and loss of texture.
