A team of engineers, scientists and student interns from ERDC’s laboratories recently instrumented an Improved Ribbon Bridge river crossing operation on the Arkansas River (July 2016). The annual exercise, spearheaded by the 467th Engineer Battalion, involved four Army and Marine bridging companies. The troops weren’t the only one learning from the experience: our Coastal and Hydraulics Laboratory Field Data Collection Branch instrumented the bridge with advanced sensors and mapped the bathymetry, currents and water levels of the river. This high-resolution data will validate ERDC's dynamic, 3D model of the IRB to inform anchorage system requirements and tradespace analyses within ERDC's Engineered Resilient Systems.
