Outline of Research at the Start

This project aims to investigate and interpret the hidden characteristics of river flow behavior and catchment dependent indicators mainly during torrential floods using an advanced automated hydroacoustic system. First, the latest improved version of the Fluvial Acoustic Tomography (FAT) system will be deployed to get temporal variations of river flow with
high-resolution. Then, precise quantification of river information, and investigations for the patterns of river flow induced by heavy floods will be performed. Thus, to clarify precise real-time dynamics of river and watershed behavior.
