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

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