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.数据分析；论证了在单向流中确定河流流向的最小声站数量可以减少到3个站，这样更实用、更容易、更经济。利用层析成像系统的三角分布，提供了连续估计流向的新准则。通过与经典监测方法的比较，从以下几个方面考察了FAT获得的长期径流记录：洪水特征和大坝对洪水的影响。河道弯曲、沙洲和洪泛平原造成的回水效应。水流线的长度和坡度以及降雨和集水区对径流水流线的影响。

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.
