Annel 2

Steady water surface profiles in circular and trapezoidal channels

Description

Annel2 is a Matlab Code for computing steady water surface profiles in circular, trapezoidal, rectangular and triangular channels in series. Gradually Varied Flows are solved by using the Standard Step Method. Hydraulic jumps are located using the momentum equation and an iterative approach. The friction loss method is chosen by the program according to whether the flow is subcritical or supercritical.
