Mapping snow depth return levels: smooth spatial modeling versus station interpolation
Mapping snow depth return levels smooth spatial modeling
2010/12/22
For adequate risk management in mountainous countries, hazard maps for extreme snow events are needed. This requires the computation of spatial estimates of return levels. In this article we use recen...
THE DEVELOPMENT OF A SNOW ROUTINE FOR THE HBV-2 MODEL
DEVELOPMENT SNOW ROUTINE HBV-2 MODEL
2009/10/29
The development of a snow routine for the HBV-2 rainfall-runoff model
is described. Experiences from field investigation that have contributed to
the work are briefly discussed.
In the snow routine...
Comparison of Areal Snow Storage Sampling Procedures for Rangeland Watersheds
Areal Snow Storage Procedures Rangeland Watersheds
2009/10/28
The accuracy of photogrammetry in determining snow depth in mountainous
rangeland watersheds was evaluated on a 0.41-km2 subbasin of the Reynolds
Creek Experimental Watershed, located in the Owyhee ...
A spatially distributed model for the simulation of snow accumulation and
melt is presented. Watershed information on topography, vegetation and soils
in digital terrain models (overlays) serve as t...
Evaporation from a Snow Cover Review and Discussion of Measurements
Evaporation Snow Cover Review Discussion of Measurements
2009/10/28
Possible evaporation rates from a snow surface with respect to available energy
and vapour pressure deficit in the air are discussed. In literature reported
measurements and measurements carried out...
Limitations in Hydrological Interpretations of the Snow Coverage
Limitations Hydrological Interpretations Snow Coverage
2009/10/28
Patterns of the disappearing seasonal snow cover are similar year after year.
This could lead to the assumption that a certain areal extent of snow indicates
always a corresponding volume of snow or...
Snow Surface Measurements from Digital Landsat MSS Data
Snow Surface Measurements Digital Landsat MSS Data
2009/10/28
The snow cover is an important parameter for water run-off prediction in high
mountain areas. At present its seasonal changes can be monitored regularly by
satellite. The paper presents a new method...
A Growth Model for Black Ice,Snow Ice and Snow Thickness in Subarctic Basins
Growth Model Black Ice Snow Ice Snow Thickness Subarctic Basins
2009/10/28
A model for the growth of ice thickness in autumn and winter is presented.
Temperature of the upper surface of the ice sheet, snowfall and heat flux from
the water are external input variables, and ...
Correction of Measured Precipitation in the Alps Using the Water Equivalent of New Snow

2009/10/28
The Hellmann heated siphon pluviograph with wind shield shows 56 % less
winter precipitation than measured on a snow board at an altitude of 2,540 m
a.s.1. For the Swiss heated tipping bucket gauge ...

2009/10/28
The results presented in this study indicate the possibility of seasonal runoff
prediction when satellite-derived basin snow-cover data are related to point
source river discharge data for a number ...

2009/10/27
From 1969 to 1980, each March, snow depth and water equivalent were sampled
around 249 pins of a grid covering the forested portion of Marmot Creek
basin. Continuous record from four snow pillows an...
