As a subdiscipline of water resources engineering, open-channel hydraulics is of critical importance to human history. This chapter starts with a brief history of open-channel hydraulics. Then the fundamental concepts in open-channel hydraulics (specific energy, momentum, and resistance) are introduced. The new development on the subject of openchannel flow modeling is discussed at some length. A general introduction on 1D, 2D, and 3D computer modeling and examples will be given. Despite the tremendous progress made in the past, modern and future challenges include revisiting past projects which were designed using less than ideal standards, effect of climate variability, and natural open channels in the arid environment. The chapter concludes with a discussion of potential future directions.
