River Hydraulics

AIM

This course covers the hydraulics of open-channel flows, the design of fundamental river structures, sediment properties, criteria for incipient motion, the formation of bed forms, the flow resistance of movable beds, bed load and suspended load transport mechanisms, the calculation of total sediment transport rates, and the design of stable channel cross-sections.
