Developing an innovative hydroacoustics system for river discharge monitoring and investigating watershed characteristics during torrential floods

目前的主要研究成果有： 1．证明确定单向河流中河流流向的最小声学站数量可以减少到三个站，这更实用、更容易且更具成本效益。 2．提供使用断层扫描系统的三角形分布连续估计流向的新指南。3．从以下几个方面研究FAT获得的长期径流记录与经典监测方法的比较：洪水特征和大坝对洪水过程线的影响。河道弯曲、沙洲和洪泛区造成的回水效应。过程线的持续时间和斜率以及降雨和流域对径流过程线的影响。

The main achievements of the current research are:1. Demonstrating that the minimum number of acoustic stations to determine river flow direction in unidirectional streams can be reduced to three stations which can be more practical, easier, and cost effective.2. Offering new guidelines to continuously estimate flow direction using a triangular distribution of tomographic systems.3. Investigating long-term runoff records obtained from FAT in comparison with classical monitoring approaches in terms of the following aspects: Flood characteristics and the effects of dams on flood hydrograph. Backwater effects caused by river channel bends, sand bars, and floodplains. Duration and slope of the hydrograph and the impacts of rainfall and catchment on runoff hydrograph.
