Using k Nearest Neighbor (k-NN) algorithm as a suitable approach to estimate cover-management factor of RUSLE model in Shirin Dareh basin, North Khorasan

Emad Zakeri; Hamidreza karimzadeh; Seyed Alireza Mousavi

Volume 73, Issue 4 , March 2021, , Pages 753-770


  Cover-management factor (C) is one of the most important influential factor on soil erosion using the Revised Universal Soil Loss Equation (RUSLE) model. C-factor is challenging to determine based on the proposed procedures due to lack of accurate information. Vegetation cover map can be used to estimate ...  Read More
