In 1984 August, there was a serious flood in the middle reaches of Heilongjiang. We pay close attention to the changes of water increase and rain conditions and mainly use the corresponding water level method and weather map to analyze the flood situation in time to release the forecast. We have successfully solved the problem that the inflow of water from the two major tributaries in Russia is not clear due to the fact that the flood exceeds the historical record and the original forecast program fails. Technical problems, and achieved good forecasting results.
