WebThe primary procedure used by HEC-RAS to compute water surface profiles assumes a steady, gradually varied flow scenario, and is called the direct step method. The basic computational procedure is based on an iterative solution of the energy equation: , which states that the total energy (H) at any given location along the stream is the sum of ... Webvelocity of the flow is constant with distance. Gradually varied flow. Depth of flow changes gradually with distance. Acceleration and deceleration of flow is neglected. Only. viscous forces are considered. Rapidly varied flow. Considerable flow depth changes within a short distance. Viscous forces are neglected and inertial forces are. css div in one line
