MARC recordNumerical simulation of river ice dynamics / A.M. Wasantha Lal, H.T. Shen.
| Title: | Numerical simulation of river ice dynamics / A.M. Wasantha Lal, H.T. Shen. |
| Author(s): | Lal, A. M. Wasantha. Shen, H. T. |
| Date: | 1992. |
| Publisher: | Southampton: Computational Mechanics Publications |

| Abstract: | Develops numerical model for simulating transport and jamming of river ice. Analysis carried out to determine characteristics of coupled hydraulics and ice dynamics equations. This shows that ice transport equations are hyperbolic, and speed of shallow waves is independent of speed of compression waves in surface ice. Hydraulic equations are coupled only through shear stress at interface between surface ice layer and water current, and are solved using 4-point implicit scheme. MacCormack method is used to solve ice transport equations. Sample simulation is presented and resulting ice-jam profile is compared with that obtained from existing ice-jam theories. |
