PAM, as a new efficient soil amendment, can significantly increase soi l infiltration rate and reduce runoff. Rainfall simulator was used in this study to investigate the relationships between the time of runoff yield and rainfall intensity and slopes, as well as the dynamic process of infiltration rate cha nge with time, for slope land at different coverage of PAM. It was found that infiltration rate and stable infiltration rate are increased when covered with P AM. Kostiakov and Horton infiltration mod...
