摘要
水位是水文测验中最基本也是最重要的观测项目之一,在长江口这样复杂多变的大型河口开展水位观测,仪器的可安装性、准确性和稳定性要求更高。对不同类型水位观测仪器的原理、性能、适用环境等进行分析评价,认为在长江口观测水位应首选浮子水位计,并以雷达水位计作为补充。实测资料表明,尽管雷达水位计存在偶然的不稳定现象,但配合后期数据处理,仍然是可靠、可行的。
Water level is one of the most basic and important observation item in hydrologic survey.In the Yangtze River Estuary,the most complex and largest estuary,to carry out water level observation,the installation,accuracy and stability of instrument should be considered more.The paper analyzes the principle,performance and applicable environment of different types of water level instruments.On the basis,it is considered that float gauge should be preferred,and radar water level gauge should be used as a supplement in the Yangtze River Estuary.The measured data shows that although radar water level gauge has occasional instability,if late data processing is used,it is still reliable and feasible.
