Green stabilization system for residual soil slope in tropics / Noorasyikin Mohammad Noh and Zainab Mohamed

Green stabilization system is a technique of slope stabilization using biotechnical system in order to prevent slope failure. Failure of residual soil slope is normally shallow type in nature but has significant effect to the slope long term global stability. Over decades, many philosophies and tech...
