HELE I: Hydraulic Elements I Key Features - Pipeflow normal depth and critical depth factors including: - Velocity - Flow area - Flow top-width - Hydraulic depth - Pressure-plus-momentum - Froude number - Estimates the lower of 2 possible normal depths when applicable. - Gradually varied flow profiles for trapezoidal, v-ditch, rectangular, and pipe channels, which includes profile computations for: - Ml, M2, M3 - C1, C2 - S1, S2, S3 - Evaluates hydraulic control and water surface profile. Estimates approximate location of hydraulic jumps by calculating: - Depth - Distance from control - Specific energy - Pressure-plus-momentum - Pipe Junction module for coupled pressure and open channel flow pressure-plus-momentum analysis using the Thompson equation. - Normal and critical depth flow factors for trapezoidal, v-ditch, and rectangular channels, which include computations for: - Velocity - Flow area - Flow top-width - Hydraulic depth - Pressure-plus-momentum - Froude number - Symmetrical street normal depth computation whereby the user "builds" a symmetrical street and specifies the streetflow. Evaluates: - Split flow - Flow factors - Velocity-depth product - Normal depth - Flood-width - Estimates open channel flow pressure-plus-momentum balance for pipeflow junctions. - Catch Basin analysis and sizing estimation module. - More than 100 computational features provide the hydraulic engineer with a comprehensive computerized hydraulics modeling package.
