Analysis of Forecast and Early Warning of Flood in Medium and Small Rivers

Abstract

Flooding of small and medium rivers is caused by environmental factors like rainfall and soil loosening. With the development and application of technologies such as the Internet of Things and big data, the disaster supervision and management of large river basins in China has improved over the years. However, due to the frequent floods in small and medium-sized rivers in our country, the current prediction and early warning of small and medium-sized rivers is not accurate enough; it is difficult to realize real-time monitoring of small and medium-sized rivers, and it is also impossible to obtain corresponding data and information in time. Therefore, the construction and application of small and medium-sized river prediction and early warning systems should be further improved. This paper presents an analysis and discussion on flood forecasting and early warning systems for small and medium-sized rivers in detail, and corresponding strategies to improve the effect of forecasting and early warning systems are proposed.
