摘要
在系统分析龙口水域水文特点的基础上,基于GPS PPK测量技术,设计并研制出了浮球漂流水位连续测量系统。对系统测量数据的处理方法进行了详细研究。将该系统及数据处理算法应用于龙口水域截流区的连续水位测量和提取中,取得了理想的效果。
Based on analyzing the hydrologic characteristics at high-velocity and acute fall water area,a set of theories for surveying water level in the water area are studied in the paper.At the same time,a system for water level observation is also developed and presented in the paper.The system and theories presented in this paper has been used in the project of Qing Cao Sha river closure.Comparing the tidal level from the method and that from tidal gauge,6-centimeter accuracy was achieved in the project,which shows that the method is right and the system is credible in the determination of water level at the special water area.
