Calibration of a mathematical model of Marukh Glacier, Western Caucasus
Considered in the paper, three-dimentsional mathematical model of dynamics of Marukh Glacier, Western Caucasus. Block structure of the model and interaction between blocs is described. Key model parameters are calibrated using field radio-echo-sounding, topographic and gravimetrical measurements, as...

Considered in the paper, three-dimentsional mathematical model of dynamics of Marukh Glacier, Western Caucasus. Block structure of the model and interaction between blocs is described. Key model parameters are calibrated using field radio-echo-sounding, topographic and gravimetrical measurements, as well as observations on surface air temperature and precipitation amount at Klukhorsky Pereval meteostation, closest to the glacier. We determine meanings of parameters favourable to minimum deviations between calculated and observed flow velocities and normalized surface mass balance. The model is supposed to be used in future for prognostic calculations of Caucasus glacier evolution in changing climatic conditions. |
