Long-term influence of port construction on coastal watershed and development of a new design method for port entrance

We clarified the strong influences of anthropogenic modification including port construction on the morphological variations in an integrated watershed composed of the Tedori River and the Kaetsu Coast on decadal scales. Additionally, we proposed a new wave-control method to attenuate the incident waves to port entrance by deeply dredging a navigation channel. Furthermore, we developed a local remote sensing system to measure the coastal morphology on sandy beaches in a cost efficient way.
