Abstract:

In recent years, city flood control is too increasingly outstanding with urban economics and scope increasing rapidly in Jinan. The government not only puts emphasis on the  engineering measure, but also non-engineering measure development. All kinds of data were gathered including geography data, water facilities, historical rainfall and water data and flood disaster data. Rainfall and water auto-collection  systems were  built. Predicting the evolving course of river flood  and the wateraccumulating depth of the low-lying region were based on the urban flood simulation model. Flood control preplan database was developed for providing consultation  for future analogous flood disasters. Flood briefing and flood issuing mode were studied. GIS flat was developed based on the above-mentioned works for providing decision-making foundations.

Key words: urban flood control, early warning decision-making support system, flood simulation, information preplan database, flood briefing
