Evaluation and development of cut-slope assessment systems for peninsular Malaysia in predicting landslides in granitic formation

Penilaian cerun dijalankan bagi meramal kebarangkalian berlakunya kejadian tanah runtuh dan juga tahap kemusnahannya di sesuatu kawasan yang dinilai. Dalam kertas kerja ini, empat sistem penilaian cerun (SAS) sedia ada bagi meramal kejadian tanah runtuh pada skala mikro yang telah dibangunkan oleh J...
