Özet

Depending on the flow conditions, the hydraulic jump may occur in the form of both A-jump and B-jump in a rectangular channel with an abrupt drop and constant width. Also depending on this flow condition, "Wave-type flows" may occur between these two flow types. Because, all of these flow types should occur and remain within the stilling basin. The length, height and width of the stilling basin are an important parameter, that should be known in designing of stilling basins. For sizing of stilling basins, flow geometries are as important as these flow conditions. In the present study; the "Wave-type flow" and its geometric properties are experimentally investigated and the results are compared with the available data. In conjunction with the test results; the simple empirical expressions that predict the geometric properties of the maximum Wave-type flow are developed. These empirical expression with the simplest and comprehensible form predict the results better than available empirical expressions.
