The Changing Impact of Snow Conditions and Refreezing on the Mass Balance of an Idealized Svalbard Glacier

Glacier surface melt and runoff depend strongly on seasonal and perennial snow (firn) conditions. Not only does the presence of snow and firn directly affect melt rates by reflecting solar radiation, it may also act as a buffer against mass loss by storing melt water in refrozen or liquid form. In Svalbard, ongoing and projected amplified climate change with respect to the global mean change ha...

Modelling Daily Runoff from Snow and Glacier Melt Using Remote Sensing Data

In this paper we present runoff simulations for snow and icemelt for the basins of Rhine-Felsberg, RhôneSion and Ticino-Bellinzona. We use high resolution multispectral remote sensing data to map snow and ice cover of selected years. Further, we use GIS based extrapolation techniques to evaluate cloud and forest covered areas with respect to snow cover. We use the deterministic hydrologic model...

Investigating the Effect of Surface Gravel Cover on Runoff and Soil Erosion with Simulating Runoff

Surface gravel cover is an important factor for contoroling of soil erosion in dry area specially in area that plant can not grow because of excessive dryness and salinity. The objective of this study was investigation effect of different surface gravel cover on runoff and sediment yeild. For this porpose, 36 field plots with 20 meter length and 0.5 meter width at 3 percent slope were construct...

The refreezing of melt ponds on Arctic sea ice

The presence of melt ponds on the surface of Arctic sea ice significantly reduces its albedo, inducing a positive feedback leading to sea ice thinning. While the role of melt ponds in enhancing the summer melt of sea ice is well known, their impact on suppressing winter freezing of sea ice has, hitherto, received less attention. Melt ponds freeze by forming an ice lid at the upper surface, whic...

Simulating pan-Arctic runoff with a macro-scale terrestrial water balance model

A terrestrial hydrological model, developed to simulate the high-latitude water cycle, is described, along with comparisons with observed data across the pan-Arctic drainage basin. Gridded fields of plant rooting depth, soil characteristics (texture, organic content), vegetation, and daily time series of precipitation and air temperature provide the primary inputs used to derive simulated runof...
