WebFeb 1, 2024 · Breakup ice jams are a prominent and important feature of rivers in cold regions. An ice jam is a large, jumbled accumulation of broken river ice that partially … WebIce jam frequencies vary considerably through time and as a function of the time scale considered for the analysis. Second, we demonstrate that large scale river ice surveys enable characterization of the spatial variations of ice jamming activity within watersheds and help to identify sites where this activity is most frequent.
