An Estimation of the Texture of Free Falling Water Based on Hydraulic Theories and its Application to a Water Design Method

Abstract

The attractive texture of falling water adds a special feature to the riverscape. But it is seldom that the texture is considered in designing a river structure. Even an artificial waterfall is designed based on the experience of a designer without objective consideration. In this paper, focusing on free falling water, the authors tried to classify the texture by observing in the field, determine the primary factors of the texture by applying the hydraulic formulas, and compare the texture of the existing falling waters to the estimated ones. the authors proposed the method of estimation and design for falling water.
