Shallow River Ice Flow Impacts on Critical Infrastructure

Ice jams cause floods that damage critical infrastructure and threaten lives. Ice flows damage piers and other in-river structures. The present project is intended to provide better predictive models for ice flows and ice jams by incorporating high-accuracy field measurements with detailed hydraulics models. In particular, the focus of this project is on shallow, alluvial streams; streams that are subject to the widespread grounding of floating ice. The goals of the project are to (1) measure critical geometries and motions associated with floating and embedded ice – performed using high accuracy unmanned aircraft systems (UAS)/drone surveys, Structure-from-Motion, and Large-scale Particle Tracking techniques; (2) Map ice jams and upstream ice flows at high spatial resolution – performed using high-accuracy UAS/drone surveys with GNSS/Global Positioning System (GPS) control; and (3) Develop a predictive model for the observed ice jams, a model based on pre-existing hydraulics models and the detailed information collected in the field. The result of the study will be a better predictive model for ice jams in shallow alluvial rivers – a model that will be shared with the Nebraska Department of Transportation and other stakeholders.
