| Zusammenfassung |
| The heat loss theory and the hydraulic theory for the analysis of the
development of wide channel ice jams are discussed and shown. The heat loss
theory has been used in Iceland for a long time, while the hydraulic theory
largely follows the classical ice-jam build-up theories used in known CFD
models. The results are combined in a new method to calculate the maximum
thickness and the extent of an ice jam. The results compare favorably to the
HEC-RAS model for the development of a very large ice jam in Thjorsa River
in Iceland, and have been found in good agreement with historical data, collected
where a hydroelectric dam project, Urridafoss, is being planned in the
Thjorsa River. |
