HEC-FIA Applications Guide contains examples that demonstrate the various aspects of HEC-FIA. Each example consists of a problem description, data for the analysis, step by step input and explanation of results.
HEC-FIA Technical Reference Manual describes the theory and computational methodology behind the HEC-FIA computations. Equations are presented which allow the user to understand how various inputs impact results.
This User's Manual, the HEC-FIA Applications Guide, Technical Reference Manual, and the HEC-FIA Version software are available for download for free from the HEC web site (http://www.hec.usace.army.mil/software/hec-fia/).
