WebThe flow is gradually varied because the assumption of hydrostatic pressure distribution is valid (vertical accelerations are negligible). The Saint Venant equations are a set of two (mass and momentum) nonlinear (actually quasi-linear) partial differential equations describing the movement of water in one dimension (x). WebThe non-uniform flow can be classified as gradually varied flow (GVF) and rapidly varied flow (RVF). Varied flow assumes that no flow is externally added to or taken out of channel system and hence the volume of water in a known time interval is conserved in the channel system and hence the volume of water in a known time interval is conserved ...
