| Summary: | Recently, mudflow has been happening on a more frequent basis due to the rapid
development especially in the mountainous and highland areas. Mudflow is known to
have devastating impacts on lives and properties. One of the most probable causes of
mudflow is deforestation. Mudflow is hard to be predicted but mitigation plans can be
developed to reduce the negative impacts of mudflow. Numerical modelling can be a
handy tool to predict the dynamics and flow extent of a mudflow disaster and therefore
it can be very useful and indispensable tool to develop a sound mitigation plan. In this
work, a higher order numerical scheme known as the cubic interpolation profile (CIP)
was adopted in the numerical model. Like other numerical models, this numerical model
was verified with analytical solution, numerical solution and experimental results
obtained by past researchers. The numerical model was used to simulate mudflow
scenarios after ensuring that the performance of the numerical model was satisfactory
through the close agreement between the results produced by the numerical model and
the data obtained from literature in the verification process. The model can be extended
for practical use by incorporating geospatial data in the near future. |
