The paper specifies the development marks of the logistic support system at a flood-prevention and its mater-of-fact oriented volume with the elements structure which respond to development of the floods risks and menace. The mentions the integration tendencies in up-to-date database information systems by reason of which the logistic processes crisis management of protection and saving in a defined endangered territorial locality will become more effective. Geographical Information Systems (GIS) for generation maps of flood risks and modelling predicted flowage maps are the base of study case. The databases characterizing identity, place and number of persons and elements of the protected interests entities and elements and place of a territorial infrastructure including potential of the disposable humane interests and technical and technological capacities are continued the bases. There is the idea of harmonizing crisis management of a logistic support in real time in the visual map of an operation centre of the integrated safety system by means of using development information base concept in the end of this paper.
