Hec-2 manual

 · FEMA has adopted the guidance that hydraulic analyses for newly contracted studies and restudies of entire watersheds (with detailed HEC-2 hydraulic analyses) should be conducted using the HEC-RAS program instead of the HEC-2 program. This floodplain modeling manual is prepared as a guide to introduce the HEC-RAS Version modeling procedures to . The HEC-RAS User's Manual and the HEC-RAS Hydraulics Reference Manual provide details on computational differences between the HEC-2 and HEC-RAS and guidance on simulating HEC-2 results; such manuals should be consulted to explain the differences between the Effective and Duplicate Effective Models. HEC-2 User's Manual, available from the Hydrologic Engineering Center provides the input specifications for the program. User Manual editions singe August include this training document as an.

The HEC-2 is factory preset for “dE” Delta-T Mode at 20°F ΔT. To change operating mode, see “Programming the HEC-2 Circulator”. Operate the circulator for a minimum of 5 minutes immediately after flushing the system to purge remaining air from the circulator. In , the Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers released a river hydraulics program under the name HEC It was the second in a series of generalized computer programs issued by the Corps. It allows a user to compute the water. This manual documents Version of HEC-2, released February Appendices provide sample applications, floodway options, bridge and culvert analysis.
