Equivalent Channel Transformation of Boundary Conditions of Unsteady Flows in Water Diversion Projects

The complexity of simulation of the unsteady flows in water diversion projects depends on how to describe their boundary conditions.This paper presented a new method for dealing with the boundary conditions of nodes.Using this new method,the gate,multi-function automatic adjustment weir-well and regulation pond as well as pumping station etc.can be replaced by an equivalent channel in mathematics except bifurcating nodes.As a result,the boundary conditions of the nodes can be described using a uniform standard mathematical model to make the computation of unsteady flow to normalize.

Key words:water diversion project,unsteady flow,boundary condition,equivalent channel
