A pre-alarming model of loss of lives in a dam-break event is developed using the GIS techniques, a linear weighted model and model indexes of flood risk, vulnerability of hazard-affected bodies and engineering defense capability. Factors of these indexes and the calculation of their weighted coefficients are discussed. By this model, pre-alarming information maps of life loss can be drawn through an analysis on the spatial data and a conjoint analysis of spatial data with attribute data of GIS. Applications show that GIS technology is a valuable tool to the development of effective pre-alarming model, particularly in accounting for the factors' variations over a wide region. The model provides a technical and valuable support to planning and preparing the rescue and migrating in dam emergency. © Copyright.

An optimization problem of emergency evacuation route for downstream community after dambreak has two aspects. One is optimization of evacuation route, and the other is optimal distribution of risk population over the route. Both are key technologies in computer simulation of such emergency evacuation. This paper uses optimization theory and operations research to analyze this problem, and presents three kinds of optimization mechanism and the corresponding calculation formula. Applicability of the results is demonstrated in simulation examples. Copyright.
