Abstract:

This research investigates ice jams and ice flows in Nebraska rivers, which are distinct from those in other regions due to the unique fluvial geomorphology of these rivers, characterized by high sediment loads, steep gradients, and wide, braided channels. The study aims to develop a two-dimensional hydrodynamic model to predict ice jam behavior using data from uncrewed aerial system surveys of several Nebraska rivers, including the Loup and Niobrara Rivers. This model integrates platforms such as HEC-RAS 2D and QGIS with a modified Shallow Water Equation to simulate ice effects. Preliminary results indicate that ice flows significantly alter river morphology, affecting floodplain characteristics and damaging infrastructure. The research encompasses detailed site selection, data collection, and analysis of ice thickness and roughness, providing essential data for hydraulic modeling. This work not only advances the understanding of ice jams in unique geomorphological settings but also supports the design of infrastructure resilient to ice-related hazards in these regions.
