Abstract
Since July 2020, an ocean of river flood water level warning lines in the middle and lower reaches of the Yangtze River have a critical period of flood controlling. Flooding’s condition is concerned with people’s interests and safety.This paper considers how to accurately forecast the water level and fasten the construction of urban water logging and drainage during floods. Imagine a tempered gauge with thin bottom steel and solar energy gauge used both rain and drought to predict the flood level and water volume more accurately, and do well in flood prevention in advance. At the same time, the attention of urban water logging will be further combined with the displacement and rate of the reservoir in the system to reduce loss during urban flooding period.
