AB: During the winter months, rivers in the north central United States have a phenomenon occurring, which is known as "ice jams". The initial melting of the river ice causes broken ice buildup, which acts as a quasi-dam restricting the natural flow. Ice jams severely impact ecosystems and are known to cause extensive damage to the channels, as well as man-made structures. The focus of this paper is on ice jams on the Little Missouri River in North Dakota and the North Platte River in Nebraska. Previous investigations done on the Lower Platte River valley, as well as the Missouri River basin, have shown that the primary cause of ice jams on these rivers is due to the spring thaw. The initial portion of the paper will discuss the pattern of ice jams on these rivers, as well as some mitigation strategies for control of these ice jams. The second section will deal with the modeling of ice jams on these river systems using HEC-RAS. This model will be comprised of both two and three-dimensional aspects of the rivers.
