Water conservancy model metadata-based drainage basin rainfall flood model reconstruction method

The invention belongs to the crossing field of a geographic information technology and a water conservancy model technology, and particularly relates to a drainage basin rainfall flood model reconstruction method based on water conservancy model metadata. Comprising the following steps of water conservancy model metadata analysis, data preparation and inspection, initialization module construction, association reconstruction of the initialization module and conversion of reconstructed data into water conservancy model input file data. The watershed rainfall flood model data reconstruction method disclosed by the invention realizes information acquisition and structural association of various elements required in watershed rainfall flood model hydrological and hydrodynamic simulation, can be fused with a model input file, pays more attention to expression of physical significance in parameter acquisition, and has a support effect on determination and research of related parameters. 本发明属于地理信息技术和水利模型技术交叉领域，具体涉及一
