1.Field survey of flow and water qualities in estuary ; The field observations for tidal flow in the Yoshino river and quasi-3D numerical simulations were conducted, and the characteristics of tidal flow situations were understood.2.Long-term change of physical properties in estuary ; (1)Topography change in lower reaches of the Yoshino river over a period of 34 years since 1967 is analyzed statistically. (2)Long-term change of tidal constant such as mean water level and amplitude of tidal constituent were analyzed.3.Field survey of habitat distribution of tidal flat benthic animals ; Field survey of the habitat distribution of benthic animals such as Genus Uca were carried out on river-mouth flats in seven prefectures. The relationships between various environmental properties and inhabiting density were examined by HSI model.4.Field observation of sediment transport on tidal flat ; Field observations were carried out to measure the amount of sediment transport by tidal flow.5.Environmental assessment technique in estuary ; Environmental assessment technique for enlarged species such as Uca arcuata was proposed and tried for some cases.

1.河口的流量和水品质调查；进行了Yoshino河流和准3D数值模拟的潮流的现场观测，并理解了潮汐流动情况的特征。2。河口中物理性质的长期变化； （1）自1967年以来的34年以来，吉诺河下游的地形变化进行了统计分析。 （2）分析了潮汐常数的长期变化，例如平均水位和潮汐成分的振幅。底栖动物（例如UCA）栖息地分布的现场调查是在七个县的河道公寓上进行的。通过HSI模型检查了各种环境特性与居住密度之间的关系。进行现场观察以测量潮汐流的沉积物传输量。5。环境评估技术；在某些情况下，提出了针对UCA Arcuata等扩大物种（例如UCA Arcuata）的环境评估技术。我
