Morphodynamic controls on the spatial variability of tidal-bore deposits in the inshore tidal flats of the Sittaung River estuary, Myanmar

This directory contains tidal current datasets collected during field campaigns in April and December 2019 from the inshore tidal flats near Kyaiko, within the Sittaung River estuary, Myanmar. The data were recorded at three key stations. A1 – located on the lower tidal flat (refer to Figure 8), A2 – within a sandy blind tidal channel (Figures 9 and 10), and A3 – also within a sandy blind tidal channel (Figure 13). Current measurements at A1 capture the passage of breaking tidal bores, while data from A2 and A3 document undular tidal bores. These datasets provide critical insights into the spatial variability of tidal-bore dynamics and their associated flow structures across different geomorphic zones of the estuary.

本数据集目录包含2019年4月与12月在缅甸锡当河河口凯乔（Kyaiko）附近近岸潮滩开展野外实地观测所采集的潮流数据集。数据在三个关键测站完成采集：A1测站位于低潮滩（参见图8）；A2测站地处沙质盲潮沟内（参见图9、图10）；A3测站同样位于沙质盲潮沟内（参见图13）。A1测站的潮流观测记录了破碎涌潮（tidal bore）的过境过程，而A2、A3测站的数据则记载了波动型涌潮的相关特征。本数据集可为解析该河口不同地貌区的涌潮动力过程及其伴随流场结构的空间变异规律提供关键支撑。
