HEC-RAS River Analysis System

HEC-RAS is an integrated system of software, designed for interactive use in a multi-tasking, multi-user network environment. The system is comprised of a graphical user interface (GUI), separate hydraulic analysis components, data

computations. A key element is that all three components will use a common geometric data representation and common geometric and hydraulic computation routines. In addition to the three hydraulic analysis components, the system contains several hydraulic design features that can be invoked once the basic water surface profiles are computed.

14 Gradually Varied Flow Profiles Physical laws governing the head variation in open channel flow 1) Gravity (So) is the driving force for flow 2) If So = Sf then dE/dx = 0 and flow is uniform (normal depth) 3) Gravity (So) is balanced by friction resistance (Sf) and longitudinal adjustment in specific energy (dE/dx)
