The Hydraulic Design tools currently include the following six hydraulic and sediment transport calculators. They are distributed between the main HEC-RAS user's manual and the sediment manual. Click the link or icon below to go to the appropriate section.
Computes a stable rock size for bank protection using the USACE guidance in EM 1110-2-1601 and applies a suite of general and bend scour equations to help design toe protection.
A suite of tools (including tractive force, Lane, and Copeland methods) that compute the hydraulic geometry that is in transport equilibrium with the flow and sediment in a channel, or visa versa.
Simplified calculator that computes sediment transport capacity for a steady flow profile - with a suite of sediment transport equations - ignoring supply, flux, or feedback that make a sediment transport model both more useful, and more difficult.
The Sediment Impact Analysis Methods is a sediment budget tool that uses steady flow results from HEC-RAS, transport functions, and user specifications of watershed and point-source loads to screen sediment impacts alternatives on a watershed scale.
Imports sediment load, concentration, and load-gradation data and leads analysts through common statistical and conceptual analyses to help them fit an appropriate rating curve through the data cloud.
