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

目前研究的主要成果有：1.论证了在单向河流中确定河流流向的最少声学站数目可以减少到3个，更实用、更容易、更具成本效益。提供了使用层析成像系统的三角形分布来连续估计血流方向的新指南。从洪水特性和大坝对洪水过程的影响等方面，对FAT获得的长期径流记录与经典监测方法进行了比较。河道弯曲、沙洲和泛滥平原造成的回水效应。过程线的历时和坡度以及降雨和集水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.
