1D/2D Modeling Programs, Calibration, and Application Moderator
Author: Dave Claman (IOWADOT)
This presentation will expand on the extensive benefits the Iowa DOT has discovered by utilizing 2-D hydraulic modeling for bridge and culvert projects throughout the state. The presentation will provide valuable insight on the limitations and restrictions of 1-D hydraulic modeling versus the many benefits of 2-D modeling for complex hydraulic situations. The Iowa Department of Transportation has reviewed several projects where HEC-RAS modeling failed to accurately depict effective flow conveyance areas and correct energy grade lines for road/bridge crossings. Audience will also learn how 2-D modeling can solve the “no-rise” issue for new bridges (piers) encroaching upon a regulatory floodway.
