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).
