Abstract
On August 21, 1986, Lake Nyos in Cameroon
released a large cloud of Carbon dioxide and suffocated people
and livestock up to 25 km from the lake. To model the scenario -
Complex Hazardous Air Release Model (CHARM) - a
sophisticated tool has been used to simulate hazardous accidental
release. This study covers process of data acquisition and its
utilization in CHARM to see the impact in both 2-D and 3-D.
Simulation was performed to demonstrate an example of a
software tool that can be used to analyze a real-world scenario of
chemical release. Real-world release modeling requires actual
terrain data, meteorological information, and impact levels and
the study describes bringing all that information together to
compare the simulation results with the real-world reported
impacts. Model was set to run to visualize impact and it was
found that upto 10 km area affected from released location in 3
minutes duration contrary to 23 km as mentioned in research [1].
Affected area reported in literature up to 23 km or 25 km implies
that the distances given are travel distances following the terrain
and not distances following a bee-line (Straight line).
