Hydraulics Channel GVF

Hydraulics Channel GVF is a calculation tool for open-channel hydraulics. It computes water surface profiles along a prismatic channel, that is, a reach whose cross-section shape and bed slope do not change along its length, for the case of gradually varied flow: the regime in which depth changes slowly enough with distance that the flow can be treated as one-dimensional and the pressure distribution as hydrostatic at each section. The output of interest is how flow depth develops from one end of the reach to the other.

The scope is narrow by design. This is an aid for one class of problem rather than a general hydraulic modelling environment, which makes it relevant to civil and hydraulic engineering coursework and to practitioners who want a second computation of a backwater or drawdown profile alongside their own working.

The entry is published by Mohamed HAFIANE under the GPL-3.0-or-later licence, and Linux is the only platform listed, so users on other operating systems would need a Linux environment to run it. Because the licence is a copyleft one, the underlying computation can be read and adapted rather than taken on trust.
