密度躍層のある場における濁水の挙動に関する研究 (4) -貯水池濁度の解析手法を中心として-

Abstract

The flow patterns in density straitfied reservoirs are clarified. One of these patterns, whichwe call type I in this study, is as follows. In upstream side of the plunging point, there forms aflow in which the mixing action is large, then the current is transformed into a density underflowon bed, and then a middle layer flow is formed between the sub-thermocline forming near surfaceand the main one forming at the depth of intake work.Considering these flow patterns, the numerical model is presented to analize the turbiditydistribution in reservoirs. Of course, the method comprizes the profiles of velocity and diffusioncoefficients developed by authors in each flow pattern.The method is applied to the turbid water phenomena occurred at Kazaya reservoir and provedto be appropriate.
