Mathematical model - GoverningEquationsThe model solves the momentum equationsFree surface elevation for the flow is calculated by thedepth-integrated continuity equation:Because many open channel flows are shallow waterproblems, the effect <strong>of</strong> vertical motion is usually <strong>of</strong>insignificant magnitude. The depth integrated 2Dequations are generally accepted for studying the openchannel hydraulics with resonable accuracy.The CCHE2D model uses the Efficient Element Method(special finite element method) to discretize the 2D depthaveraged shallow water flow equations.Continuity equation <strong>of</strong> bedload, bed changes - massbalance equation
