Design and application of a disaster situation mobile phone APP for rainstorm flooding

According to the business requirements of rainstorm flooding risk warning, zonation and evaluation, this paper proposes a new method for rapid acquisition of disaster condition. Based on designing technological flow and setting disaster recording contents, the key techniques in the process of real-time rainstorm flooding disaster investigation are discussed, including task receiving, site location, the integration of acquisition, and real-time data ransmission. Then a mobile phone APP for disaster information collecting is introduced. The practical test in flood season shows that the method of rainstorm flood disaster information collecting and the mobile phone APP can provide real-time data for disaster validation and evaluation, and meet the requirements of practical application.
