Accumulation and evolution of ice jams influenced by different ice discharge: An experimental analysis

Ice jam, a unique hydrological phenomenon of rivers in cold regions, is major cause ice flooding. There are many different kinds damage that can result from jams: e.g., blockage the water flow, rising levels flood farmland and dwellings, to hydraulic structures, interruptions shipping. The formation an jam influenced by various factors associated with fields study. accumulation thus complex process worth investigating. However, previous studies seldom take account discharge factors. This study carries out 29 tests on discovers four phenomena: inlet fails submerge (case 1); thickening upstream downstream 2); 3); failure form 4). Two typical examples used detail cases 2 3. authors suggest differentiating between two using longitudinal boundary line running through point Froude number (Fr) = 0.119. Furthermore, analyze phenomena make it difficult for critical discriminant distinguish 3 4. Combined line, partition diagram features jams presented differentiate modes jams.
