Flooding in Brisbane and Australia – need for dam water release simulation model
It is all over CNN and the cable news. Brisbane has been hit by an “inland tsunami” arising from dam water release at the height of a typhoon and massive rainfall over the past few days.
It appears that the dam above Brisbane that was designed to protect it from flooding experienced in 1976 released excess water in order to avoid serious damage to the dam structure itself.
This article below will perhaps help the Australian authorities in calculating the needed advanced warning and time for pre-emptive discharge in order to remove excess water at a safe rate so that the incoming storm could be safely contained by the dam. Having sufficient storage capacity of at least one storm (4-6 meters to handle one storm) is a must that should be maintained at all times, especially after a previous storm has exited and an incoming storm has been spotted by the weather bureau through Doppler Radar which locates storms and estimate its rainfall potential.
