Submerged pressure transducers are studied for measuring shallow water stream, river, and estuarine depth and flow rates. Signal processing of the transducer output could, in principle, lead to the extraction of a signal corresponding to the upstream and downstream propagation of a surface wave whose propagation speed is uniquely related to water depth. The research will explore the possibility of utilizing this principle in a practical, useful way.

研究了用于测量浅水的淹没式压力传感器 溪流、河流和河口的深度和流速。 信号处理 原则上，传感器输出的变化可能导致 对应于信号的上行和下行传播的信号， 传播速度只与水有关的表面波 深入 该研究将探讨利用这一点的可能性， 原则，以实用的方式。
