A separate addendum consisting of the complete FHWA documentation for HEC-12 "Design of Highway Pavements" is provided as part of the documentation for user training courses. Contact your account representative for additional information.
This implementation of HEC-12 supports:
Gutter Depression
The capture efficiency of an inlet can be increased by having a locally depressed gutter section (inches, mm).
The inlets may be located on either continuous grades or in sumps.
