Abstract

The invention discloses a flood risk prediction method based on a rainstorm process, and relates to the technical field of flood risk prediction, comprising the following steps: pre-collecting meteorological data during the flood occurrence period of the area to be measured, and obtaining airflow trajectory information of the corresponding period based on the HYSPLIT model ;Collect GFS information and use it as the input information of WRF model initial data field data, and carry out downscaling numerical simulation of various types of flood-causing storm processes; Based on the obtained flood hazard characteristic information, flood exposure characteristic information and social vulnerability Based on the characteristic information, assess the flood risk and determine the flood risk level; based on the precipitation storm center and time distribution in the area to be measured, the flood risk level and the occurrence law of the flood process line, the disaster-caused flood is predicted. The invention realizes flood risk assessment from multiple angles, not only has high flood prediction accuracy, but also can observe water vapor, has high prediction accuracy and wide adaptability.

Description

technical field [0001] The invention relates to the technical field of flood risk prediction, in particular to a flood risk prediction method based on a rainstorm process. Background technique [0002] Precipitation is an important link in the circulation process of hydrological system. With the expansion of precipitation range, increase of precipitation amount and increase of precipitation intensity, the destructive power of flood is also increasing. As a result, it will cause serious harm to the economic development of the entire region. For this reason, how to better predict floods in a relatively short period of time is one of the key issues that need to be solved urgently in the field of water information. [0003] At present, the occurrence of most mountain torrent disasters is mainly caused by heavy rain. Rainstorms that cause floods are called "flood-causing rainstorms." High-quality and high-resolution rainfall forecast is one of the important prerequisites for fl...
