Gradually varied flow excel
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 … WebIn this chapter, methods to compute gradually varied flows are presented. Preference is given to the methods suitable for a computer solution. Two traditional methods – commonly referred to as the direct and standard step methods – are first presented. The computations progress step by step from one section to the next in these methods.
