Polyacrylamide effects on splash erosion rate in different soils using rainfall simulator

Ataollah Kavian; Feryal Hayavi; Mehdi Boroghani

Volume 67, Issue 2 , July 2014, , Pages 203-216


  Splash erosion recognized as first stage of erosion process that results of bombing soil surface with rain drop. Falling rain drops to soil surface resulted moving soil particles and destructing soil structure. At this research effects of various PAM rate (0, 2, 4 and 6 kg.ha) on splash erosion on three ...  Read More
