What Is Flood Certification?

Flood monitoring refers to the process of providing real-time measurement factors such as water conditions and rain conditions of rivers, lakes, reservoirs, or other water bodies by setting up water regime stations in order to prevent floods from harming the environment. The hydrological station can provide real-time hydrological information to relevant departments within a specified time and according to certain standards. ^[1-2]

Under the leadership of the party and government, China's vast number of hydrotechnical workers and employees monitor the development of water during the day and night, and timely forecast floods, rainstorms and flood conditions.

Meteorological experts summarize the experience of rainstorm forecast, first find out which factors have an impact on the rainstorm, and put forward countermeasures to avoid the harm caused by the rainstorm. It has made great contributions to mitigating and preventing flood disasters and winning victory in flood control.

The occurrence of flood disasters generally has sudden characteristics. To carry out early warning and forecast of flood disasters, to provide relief and to arrange post-disaster reconstruction, timely, accurate and reliable collection and feedback of flood disaster related information is required. However, the traditional manual-based information collection methods, processes and levels have been difficult to meet the needs of flood prevention and flood resistance. The remote sensing technology developed in the 1960s has been used more and more in the research of natural disasters such as floods because of its advantages such as large observation range, large amount of acquired information, fast speed, good real-time performance and strong dynamics. The application of remote sensing technology in the prevention and control of natural disasters in China can be divided into four stages, that is, the initial stage in the 1970s; the initial development stage in the 1980s; the rapid development stage in the first half of the 1990s; the practical application after the 1990s stage. After 30 to 40 years of exploration and application and practice, remote sensing application fields and methods have been formed throughout the whole process before, during and after the disaster. Weather forecasting through the information obtained by remote sensing satellites is a well-known thing. Meteorological satellites can monitor the weather conditions in the area in real time, thereby inferring their changing trends and providing rainfall factor information for flood forecasting. In addition, the use of remote sensing images can accurately and quickly determine the catchment area of the watershed, and through a comprehensive analysis of the underlying surface, the production and convergence of the study area can be inferred. Using remote sensing technology can provide basic information for flood forecasting and forecasting. ^[1]
