Modelling Snow Water Conservation on the Canadian Prairies
Modelling Snow Water Conservation the Canadian Prairies
2014/4/2
Snowcover accumulation has tremendous impacts on Canadian Prairie hydrology and agriculture (Pomeroy and Gray, 1995; Fang and Pomeroy, 2007). Wind redistribution of snow or blowing snow is frequent in...
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...
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...
Use of satellite-derived data for characterization of snow cover and simulation of snowmelt runoff through a distributed physically based model of runoff generation
satellite-derived data snow cover snowmelt runoff runoff generation
2010/3/5
A technique of using satellite-derived data for constructing continuous snow characteristics fields for distributed snowmelt runoff simulation is presented. The satellite-derived data and the availabl...
The physical basis for and the various methods of measuring the water
equivalent of the snow cover by means of gamma-rays survey from aircraft
are discussed.Problcms of mapping the water equivalent ...
SNOW-WATER EQUIVALENT MEASUREMENT USING NATURAL GAMMA EMISSION
SNOW-WATER EQUIVALENT MEASUREMENT NATURAL GAMMA EMISSION
2009/10/29
The natural gamma radiation emitted by potassium, uranium and thorium
is attcnuated by snow. This attenuation depends on the water-equivalent
of the snow layer. Air absorption coefficients were dete...
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...
Chemical Budgets and Chemical Quality of Snow and Runoff During Spring Snowmelt
Chemical Budgets Chemical Quality Spring Snowmelt
2009/10/28
In connection with water acidification and the subsequent disappearance of
fish populations and also massive fish kills during spring floods, particular
interest has been focused upon the fate and e...
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...
Meltwater Hydrology and Hydrochemistry in Snow- and Ice-Covered Mountain Catchments
Meltwater Hydrology Hydrochemistry Snow- and Ice-Covered Mountain Catchments
2009/10/28
Electrical conductivity, a surrogate measure of total dissolved solids content,
and discharge of meltwaters draining from two adjacent contrasting watersheds
in the Rocky Mountains, Canada, were rec...
Isotope Input into Runoff Systems from Melting Snow Covers
Isotope Input Runoff Systems Melting Snow Covers
2009/10/28
Stable environmental isotope techniques contribute to reasonable separations
of the direct runoff component in snowmelt hydrographs. For the separation
procedure, the actual isotope input from snow ...
