Gradually-varied circulation (GVF) is a gentle non-uniform stream in an open channel with sluggish adjustments in its water floor elevation. The assessment of GVF profiles less than a particular move discharge is essential in hydraulic engineering. This ebook proposes a unique method of analytically clear up the GVF profiles by utilizing the direct integration and Gaussian hypergeometric functionality. either normal-depth- and critical-depth-based dimensionless GVF profiles are awarded. the radical process has laid the basis to compute at one sweep the GVF profiles in a chain of maintaining and hostile channels, which could have horizontal slopes sandwiched in among them.
