Abstract

The invention relates to a flood forecasting method based on a rainfall flood space-time database. The flood forecasting method comprises the following steps that 1) the rainfall flood space-time database is constructed; 2) a dynamic space-time rainfall map is drawn according to the rainfall flood space-time database with combination of GIS map data; 3) the space-time data corresponding to all the heavy rain paths involved in the flood in the historical periods of time are acquired according to the rainfall flood space-time database, and the heavy rain paths are displayed on the space-time rainfall map; and 4) corresponding class models are acquired according to the space-time data corresponding all the heavy rain paths, and flood forecasting is performed according to the class models. Compared with the methods in the prior art, the flood forecasting method has the advantages of being connected in space and time, dynamic and visual and accurate in forecasting.

Description

technical field

[0001] The invention relates to the field of flood forecasting, in particular to a flood forecasting method based on a rainfall flood spatio-temporal database. Background technique

[0002] Based on the review of previous studies, natural disaster databases can be divided into five types, namely statistical, spatial relational, time-relational, element-relational and process-relational. At present, the research on the establishment and application of China's comprehensive natural disaster database mainly focuses on the following three aspects.

[0003] 1) Comprehensive natural disaster database and space-time regularity research. The database is a statistical database,

[0004] For example, the China Natural Disaster Database is a statistical database consisting of sub-databases such as the China Natural Disaster Causing Factor Database, the Chinese Press and Periodical Natural Disaster Information Database, the Chinese Historical Natural Disaster Database,...
