Predicting river discharge in mountainous river basins during heavy rain events using seismic noise data

这项研究的目的是展示地震数据在估计流域流量方面的应用，特别是在洪水事件期间。本研究以水文学和地震学为交叉学科，在海网观测和水文资料可获得性的基础上，选取山区河流流域进行水文模拟。然后，我们研究了Hi-Net数据和水流数据之间的关系，以及洪水事件期间的模拟流量。我们发现，附近一条河流和山区河流流域的Hi-Net流量反映了类似的模式，特别是在洪水事件的高峰期。在这一阶段，结果表明，在1-2赫兹频率范围内的地震噪声数据表现出与模拟流量值相似的趋势。对地震和河流流量数据之间的关系进行了进一步的评估。其中一些调查结果已在国内和国际会议上发表并在专题文章中介绍。

The aim of this study is to demonstrate the application of seismic data for estimating the discharge in a river basin particularly during a flooding event. This research is based on the interdisciplinary subjects i.e., Hydrology and Seismology.Based on Hi-net observations and hydrological data availability, we selected mountainous river basins for the hydrological simulations. We then examined the relationship between Hi-net data and water flow data, as well as simulated discharges during a flood event. We found that the flow of a nearby river and Hi-net in mountainous river basins reflected a similar patterns, especially during a high peak flow of the flood event. At this stage, the results indicated that seismic noise data in the frequency range of 1-2 Hz exhibited a similar trend to the simulated discharge values. Further evaluation of the relationship between seismic and river flow data has been examined. Some of these findings have been published and presented at national and international conferences and in feature article.
