Estimation of debris flow sedimentation volume through numerical modelling

Implementation of potential debris flow hazard in Malaysia has been conducted by Jabatan Kerja Raya in 2011. However, evaluation of this hazard level cannot deny the consequent to the nearest facilities. Thus, run-out analysis based on numerical modelling is the easiest and competent way to evaluate...

Civil engineering (General) Implementation of potential debris flow hazard in Malaysia has been conducted by Jabatan Kerja Raya in 2011.
