Abstract

Dam is among the biggest hydraulic structure in
terms of size and constructed area. Today, dams are often
considered from a critical angle. This includes horror stories
about their negative social and ecological effects. It is known that
dams provide many benefits to people, but it is indisputable that
some of the dams will result serious dangers to society in case of
dam failure. The purpose of this study is to produce Outflow
Hydrograph by using MIKE 11. A number of simulation models
of dam failures due to flow overtopping have been developed. The
effect of model parameters on the computed results and the
numerical stability has been investigated using sensitivity
analysis. Prediction of dam breach parameters was conducted
using Froehlich and Macdonald – Langridge-Monopolis predictor
equations. The modeling was done via MIKE 11 1-D
Hydrodynamic Model developed by Danish Hydraulics Institute
(DHI). By comparing with the actual site condition results for
operational release scenario and also based on literature review, it
was found that the model accuracy depends largely on the dam
break parameter and pore water pressure coefficient. The peak
outflow simulated due to Sultan Abu Bakar dam failure was
5439.014m3/s. The model was found to predict actual breach
outflow of the existing dams reasonably well and closer than
other existing numerical models.
