Investigation of the River Mouth Topography Change by the Response Characteristics of River Discharge and Ocean Waves at Yoneshiro River

Abstract

ABSTRACT Watanabe K. and Kumagai K., 2018. Investigation of the River Mouth Topography Change by the Response Characteristics of River Discharge and Ocean Waves at Yoneshiro River. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea). Journal of Coastal Research, Special Issue No. 85, pp. 61–65. Coconut Creek (Florida), ISSN 0749-0208. Frequent occurrence of water level rise caused with increase in abnormal weather such as the local torrential rain by the influence of the global warming. Therefore, apprehensive the saline water intrusion was generated at the tidal area due to water level rising and the River mouth topography change in recent years. Saline water intrusion was generated to go up upstream by the ocean waves during winter at the river mouth especially. Hence, riverine environment was affected from saline water intrusion. It was in particular thought river mouth shape have a high impact on tidal discharge an...
