We performed a field survey on the coasts of the upper Gulf of Thailand funded by JSPS Grant-in-Aid for Scientific Research. We visited Samut Sakhon and Samut Prakan provinces where muddy coasts have suffered from severe erosion. Several measures have been implemented to protect the coasts and to restore mangrove, including installation of bamboo fences, revetments and sand sausages.

2014年7月28日から8月3日の旅程でタイ湾奥部沿岸において泥海岸の侵食とマングローブ再生プロジェクトに関する現地調査を行いました.
