Abstract
With the construction of waterway of various levels in China,more and more sluices have been built to regulate water level effectively.The water level of reservoir is related to the safety of residents and farmland along the river,therefore the study of variation of water level is very important.In the paper the yearly variation of water level,the difference of water level hc in the current month,and the next month water level difference hn are analyzed based on the measured hydrological data of Dasi Sluice Hydrological Station in Anhui Province.The typical low water year and high water year are defined,statistics of variation law of water level in the year with different features upstream of the sluice are conducted,and the unfavorable period of water-level change is analyzed.The results show that the average monthly highest water level mostly occurs in December to February of the following year,than from June to September when rainfall is high.The hn is smaller than hc.and hn distribution has little correlation with average water level in the same year.Therefore,the watershed confluence features significantly affect the distribution of high-water level,but have little effect on the instantaneous distribution of hn and hc.关键词
