Abstract:
The hydrological dynamics of the Dudh Koshi River examined through physically based semi-distributed model, SWAT – the Soil, Water Assessment Tool, with the aim of understanding the glaciers and snowmelt contribution in the River. The analysis suggests that the model can give a fair estimation of the water yield. The river discharge is mainly dependent on precipitation. The effects of glaciers and snow are largely dependent on the basin characteristics and the glaciated area. The melt water contribution from the glaciers and snow is nearly 30% in the Dudh Koshi River. The T-index method of glacier melt estimation is a simple approach requiring only the temperature and melt factor, however use of such model underestimated the melt while using mean daily temperature data. The energy-balance model further confirmed the melt underestimation by T-index approach. The finding shows that the melting of glaciers continue until 3 C below the average mean temperature, indicating that the important role of solar radiation in such higher altitude.
