Simulation of snow accumulation and melt in needleleaf forest environments
needleleaf forest environments snow accumulation
2014/4/3
Drawing upon numerous field studies and modelling exercises of snow processes, the Cold Regions Hydrological Model (CRHM) was developed to simulate the four
season hydrological cycle in cold re...
Hydrological response unit-based blowing snow modelling over an alpine ridge
snow modelling an alpine ridge
2014/4/3
Snow redistribution by wind and the resulting accumulation regimes were simulated for
two winters over an alpine ridge transect located in the Canada Rocky Mountains. Simulations were performed using...
The progress of snow albedo for the 1991 winter from Helligdagshaugen research
site, Norway, is presented. The temporal reduction of albedo decreases
as the snow undergoes a process of metamorphosis...
Areal Extent of Seasonal Snow Cover in a Changed Climate
Areal Extent Seasonal Snow Cover Changed Climate
2009/10/26
In mountain snow basins, a change in climate will likely cause a change in the basin snow cover extent. A procedure for evaluating whether a given climate change scenario will speed up or slow down th...
The Effect of Climate Change on River Flow and Snow Cover in the NOPEX Area Simulated by a Simple Water Balance Model
Climate Change River Flow Snow Cover NOPEX Area
2009/10/23
Within the next few decades, changes in global temperature and precipitation
patterns may appear, especially at high latitudes. A simple monthly water-balance
model of the NOPEX basins was developed...
Contributions of Snow to the Annual Water Balance in Moshiri Watershed,Northern Hokkaido,Japan
Contributions of Snow Annual Water Balance Moshiri Watershed
2009/10/23
Characteristics of the water balance were investigated in an experimental watershed
where there is a seasonal snow cover. To estimate the basin-wide snowmelt
by the heat balance method, seven observ...
Arctic Snow Cover Information for Hydrological Investigations at Various Scales
Arctic Snow Cover Information Hydrological Investigations Various Scales
2009/10/23
Routine snow survey and snow gauge data provided by weather stations establish
snow-on-the-ground and snowfall time series but they lack a spatial dimension.
Of particular importance to arctic hydro...
Evaporation from Snow in the Central Sierra Nevada of California
Evaporation from Snow Central Sierra Nevada California
2009/10/23
Evaporation from snow was calculated with the mean-profile method using
single-level meteorological data at eight locations representing a variety of alpine
and sub-alpine terrain in the central Sie...
Impulse Radar Snow Surveys–Influence of Snow Density
Impulse Radar Snow Surveys Snow Density
2009/10/23
Snow cover water equivalent (SWE) is of major importance for planning of e.g.
hydropower production in areas where a large proportion of the annual precipitation
falls as snow. Radar technique can b...
Snow Cover Modelling as a Tool for Climate Change Assessment in a Swiss Alpine Catchment
Snow Cover Modelling Climate Change Assessment Swiss Alpine Catchment
2009/10/23
The daily step conceptual hydrological model IRMB (Integrated Runoff Model
= Bultot) is further developed by the addition of a module designed to calculate
the energy balance in high spatial resolut...
Preferential Flow and Melt Water Retention in Cold Snow Packs in West-Greenland
Preferential Flow Melt Water Retention Cold Snow Packs West-Greenland
2009/10/23
Runoff from seasonal snow covers in Greenland provides the major source of
stream flow in the non-glacierized catchments, and has gained interest in relation
to hydropower potentials and water suppl...
Snow Distribution at a High Arctic Site at Svalbard
Snow Distribution High Arctic Site Svalbard
2009/10/23
In the Arctic regions snow cover has a major influence on the environment both
in a hydrological and ecological context. Due to strong winds and open terrain
the snow is heavily redistributed and th...
Years with late spring in combination with thick snow-pack constitute risk for
flooding. To decrease that risk, the possibility of spreading albedo-lowering
material (wood ash) on parts of a basin s...
Regional Variations of Snow Accumulation on Spitsbergen,Svalbard,1997-99
Regional Variations Snow Accumulation Spitsbergen
2009/10/22
End-of-winter snow accumulation has been measured over large areas on Spitsbergen,
Svalbard, using Ground Penetrating Radar (GPR) in the years of 1997,
1998, and 1999. Measuring transects following ...

Snow-Distribution Modelling Ammassalik Region South East Greenland
2009/10/22
The Ammassalik region is characterized by a strong alpine relief, with altitudes
up to 1,000 m. Glaciers are located mainly on the western side of ridges. The climate
is low arctic, with annual prec...
