Mano and Goto executed continual observation at the Nakahara reservoir and analyzed heat budget to specify the boundary condition at the surface and to find diffusion coefficient as a function of Richardson number. Then the precise characteristics of oxygen production and consumption are obtained in terms of light, temperature and nutrition salts.Tanaka made observation at the Shizugawa Bay to find the condition for rapid exchange of the bay water in the effects of west wind and tidal range.Sudo has found the mechanism of Cyanobacteria domination though the cultivating mixed species as controlling factors of N/P ratio and temperature.Noike researched the effects of pre dams on removal of suspended phosphorus through a pilot plant to confirm the effectiveness and studied liquation of phosphorus under the anaerobic situation to evaluated the flux which is the latent nutrition.Ishikawa observed at Shitigashuku Dam to analyze mad, SS and phosphorus at floods condition and to find relationship among them.

Mano和Goto在Nakahara水库执行了持续的观察，并分析了热预算以指定表面的边界条件，并找到扩散系数作为Richardson数字的函数。然后，根据光，温度和营养盐来获得氧气产量和消费的精确特征。通过试验厂悬浮磷，以确认在厌氧情况下磷的有效性和研究的磷液化，以评估在shitigashuku大坝上观察到的insikawa，以分析洪水状况下的疯狂，SS和磷在洪水状态，并发现其中的关系。
