The Huai River, formerly romanized as the Hwai, is a major river in China. It is located about midway between the Yellow River and Yangtze, the two largest rivers in China, and like them runs from west to east.
Historically draining directly into the Yellow Sea, floods have changed the course of the river such that it is now a major tributary of the Yangtze.
The Huai is notoriously vulnerable to flooding and is badly hit from June this year.
During the flooding season, CW-30D and CW-10D monitoring UAVs is carrying at least 5 flights a day to give real time surveillance of Huai river.
Live video stream can be transmitted back to command center to provide advices on flood fighting at frontline.
