Life Safety Model (LSM)

HR Wallingford is working with BC Hydro on the Life Safety Model (LSM), a dynamic model that can represent people's interactions with a flood.

The Life Safety Model (LSM) provides estimates of the number of people that are likely to be injured or killed as a result of a flood event, as well as the time that is required for them to evacuate the area at risk. It also allows the loss of life and evacuation times to be assessed for a range of types of flood events including slow rising floods, dam and flood defence failures, tsunamis and flash floods.

The LSM has been piloted on a number of historical floods including the Mapasset Dam disaster that occurred in France in 1959 and the Great North Sea Flood of 1953 that inundated Canvey Island in the Thames Estuary resulting in the deaths of 58 people. It has recently been used to help to improve the emergency response of coastal communities in Canada to tsunamis and assist emergency planners in Lincolnshire in the UK.

LSM is used to assess changes in variables such as the effectiveness of warnings, road capacities, and seasonally varying population densities on evacuation times and loss of life.
