Table 5. Summary of input blocks for the Full EQuations UTiLities model
Block name
| Summary of block
|
Bridge
| Bridge hydraulics computed with the Bureau of Public Roads procedure (Bradley, 1970).
|
Channel
| Sinuosity is computed for a series of flow lines and combined with FEQX, FEQXLST, or FEQXEXT to compute cross-section function tables that include corrections coefficients for channel curvilinearity.
|
Channel rating
| Flows are computed for short, prixmatic bypass channels (for example, overland flow around culverts).
|
Critical flow
| Critical flow is computed in a given cross section assuming that the cross section represents a constriction to the flow; most often used with the GRITTER command for the generalized Ritter (1892) solution to an instantaneous dam failure.
|
Culvert
| Flows through culverts and over the associated roadway are computed.
|
Embankments and weirs
| Flows over weirs, embankments, and other weir-like structures are computed.
|
Expansion/contraction
| Flow through an expansion or contraction is computed.
|
FEQX
| Hydraulic characteristics of a cross section are computed from data in a fixed format.
|
FEQX extension
| Hydraulic characteristics of a cross section are computed. The computations are extended to consider frictionless line segments and roughness values that vary with water-surface height.
|
FEQX list
| Hydraulic characteristics of a cross section are computed from data in a list format.
|
Finish
| The files are closed and execution of FEQUTL is terminated.
|
Floodway
| A table of values is input to be used later in FEQX and FEQXLST in defining the cross-section hydraulic characteristics for a floodway analysis.
|
Function table input
| One more function tables in the format used in FEQ simulation are input.
|
Generalized Ritter dam-break method
| The generalized Ritter (1892) dam-break method for estimating the flood-peak stage at a dam site is computed.
|
HEC2X
| Cross-section input for the HEC-2 water-surface profiles model (U.S. Army Corps of Engineers, 1990a) is transformed to a format suitable for the CHANNEL command or FEQX command or for direct use in FEQ.
|
Multiple conduits
| The hydraulic characteristics are computed for one or more conduits that may be circular, rectangular, true elliptical, nominal elliptical, reinforced-concrete pipe arch, or corrugated-metal arch.
|
Multiple pipes
| The hydraulic characteristics are computed for one or more circular sections.
|
Critical-flow limit
| A limit on the critical-flow rate in a closed conduit is set so that EXPCON computations will be suitable with one or both cross sections as a closed conduit.
|
Sewer pipe
| The hydraulic characteristics are computed for a single circular section.
|
Underflow gates
| Flow through underflow gates (sluice and tainter gates) with variable gate settings is computed.
|
WSPROQZ
| Input lines for the WSPRO (Shearman, 1990) steady-flow water-surface profile model are prepared to define the flows and elevations for multiple water-surface profiles required to define the hydraulics of a bridge.
|
WSPRO14
| A two-dimensional table of type 14 is prepared using the water-surface profiles computed with WSPRO (Shearman, 1990) as defined by the WSPROQZ command.
|
WSPROX
| Cross-section input for the WSPRO water-surface profile model (Shearman, 1990) is transformed to a format suitable for the CHANNEL command or FEQXEXT command or for direct use in FEQ.
|
Cross-section interpolation
| One or more cross-section tables are interpolated from information in two specified cross-section tables.
