Research

Researches on coastal environment and disaster mitigation are conducted from the viewpoint of Coastal Engineering. We are trying to solve problems and to make clear phenomena in coastal region using field observation, data analysis and numerical simulation. We hope to create useful results for our life and community.

Theme1：Sediment Dynamics and Topographic Change in River-mouth and Coastal Region

Overview

Topographic chanes on a tidal flat measured by UAV

Sediment transport in coastal zone has a great influence on coastal erosion, topographic changes and coastal environment. We are conducting the researches on the generation of the sediment transport in coastal region (sea and river mouths), their spatial and/or temporal characteristics, the relationship among coastal high waves and currents, volumes of the sediment transport and coastal topographic changes, to aim for the protection of coastal erosion and the preservation of coastal environment Various approaches, such as field observation, laboratory experiment and numerical simulation, are used for the elucidation of related phenomena and the investigation of countermeasures. This theme is the fundamental research for preservation and management of rich coastal environment.

Keywords

Sediment movement, Topographic/bathymetric change, Field observation and survey

Theme2：Measurement / Monitoring of Sediment Movement and Coastal Morphology

Overview

Sand particle distribution obtained by image analysis

We are trying to develop and propose various measurement and monitoring methods to understand the characteristics of sediment movement and topographic/bathymetric changes in a coastal areas such as rivers, beaches and sea. For example, monitoring / measurement method for topographic changes in tidal flat area efficiently and in detail using UAV, measurement method of micro-topographical change process using image analysis, simple and easy method to obtain sand particle size information using image analysis.

Theme3：Coastal Disaster Mitigation

Overview

Changes of shoreline positions and cross-sectional profiles at Omotehama Coast (from 1999 to 2020) (Black line : shoreline distance from reference point, color : elevation)

For various disasters occurring in the coastal area, numerical simulation, field survey and their data analysis are conducted to clarify the cause of the occurrence and understand the phenomenon. For example, we conduct the analysis of the mechanism of the disaster occurrence by numerical simulation of tsunami and data analysis, counter-measures for the spread of disasters into inland and urban areas, evacuation when disasters occur. In addition, we also analyze the occurrence mechanism of shoreline change and coastal erosion based on the field surveys on the Omotehama coast facing the Enshu-nada coast. Through these researches, we aim to contribute to regional disaster prevention.
