STUDY ON THE MECHANISM OF ALGEE PROLIFERATION IN RESERVOIR AND ITS CONTROL THROUGH CONTINUAL AUTOMATIC OBSERVATION

Mano和后藤在中原水库进行了连续观测，并分析了热收支，以指定表面的边界条件，并找到扩散系数作为理查森数的函数。然后根据光获得氧产生和消耗的精确特性，Tanaka在静川湾进行了观测，发现了在西风和潮差的影响下，湾水快速交换的条件; Sudo通过培养混合种作为N/N的控制因子，发现了蓝藻优势的机制。Noike通过中试装置研究了前置坝对悬浮磷去除的影响，以确认其有效性，并研究了厌氧条件下磷的液化，以评估潜在营养物的通量。石川在Shizigashuku大坝进行了观察，以分析mad，研究了洪水条件下悬浮物和磷的变化规律，并探讨了它们之间的关系.

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.
