XS CD 01 SECNO: 298

Critical Depth occurs at 1%-annual-chance flood. Flow Code will be "C". The Ineffective flow option is used. The Ineffective Flow elevation is equal to or higher than the Critical WSEL. Please investigate whether this selection is appropriate.

XS IF 01L SECNO: 298

Flow code will be IL. The area left of the ineffective flow station may be considered effective. The 1%-annual-chance WSEL of 2302.52 is higher than the ground elevation 2301.779 of the Left Ineffective Flow Station. However, it is equal to or lower than the left ineffective flow elevation of 2307.29. The lateral structure was not modeled downstream of this River Station. Lower the ineffective flow elevation to the ground elevation to consider the area left of the ineffective flow station as effective, or model a lateral structure if the overflow will take a different flow path. The ineffective flow elevation could be accepted if the area left of the ineffective flow station is non conveyance.

XS SW 01DK SECNO: 0

The name of the stream is LIMKNRN2T1, Main. The flow regime is subcritical or mixed flow. Starting WSEL is computed from Known WSEL as the downstream boundary for 1%-annual-chance flood. Provide backup information on Known WSEL or use energy slope as the downstream boundary.
