| 内容記述 | Recently, consideration to harmony with the ecosystem is strongly requested. In headworks that are indispensable to the agricultural production of our country, the importance of fishway has increased very much. It is common that pool-and-weir type fishway is more suitable for upstream migration of fishes in a lot of types, because the energy of the flow is dissipated enough and the flow structure become comparatively simple in this type if it is designed adequately. However, there are some cases in which this type does not function fully in the field due to inadequate design. Threfore, the objective of this study was to establish the design of pool-and-weir type fishway which fulfills its merit more, provided that the structure in which the weir walls has no noch and orifice was target, because even this most simple structure has not been studied enough either. First of all, relationship between the flow structure and the swimming behavior of Leuciscus hakonensis in individual pool of pool-and-weir type fishway under a variety of discharge conditions were clarified by observations using a full-size hydraulic model composed of three pools. Next, new numerical analysis methods based on computational fluid dynamics were established for pool-and-weir type fishway whish has weir walls with circular arc shaped crown and pool-and-weir type fishway whish has weir walls with inclined crown. From a comparison with experimental measurements, it was clarified that these two methods can become accurate, efficient, general prediction procedures of the flow structure in pool-and-weir type fishway for its design and these are more accurate than existing methods. It is assumed that these a series of study results can improve the possibility to design pool-and-weir type fishway in which its merits function more fully than ever, and make this type more widely applied. In addition, these results are expected to contribute to not only constructing new one but also evaluating the performance of existing one and rehabilitating it, because most of existing fishways is this type in our country. | |||||||||||
