Study on Headwater Accidents at Lata Kinjang Waterfall, Perak. A Lattice Boltzmann Approach.

Headwater accident is a natural phenomenal that possibly to happen in every flow
channel. The headwater accidents have caused tremendous incidents that involved
vulnerable lives and destruction of its surroundings. This study focuses on the
headwater accidents at Lata Kinjang waterfall, Perak. The incident is studied by
utilizing the Lattice Boltzmann method with the aim to understand the behaviour of
headwater accidents in term of hydraulic aspects such as water height and velocity.
LABSWETM model has been used to simulate the headwater condition for Lata
Kinjang waterfall. The output from the LABSWETM model simulation is reported in
term of water height progression and velocity profile which been further analysed.
Possible mitigation measures are provided from the study.
