Multi-model comparison of a major flood in the groundwater-fed basin of the Somme River (France)
Multi-model comparison major flood groundwater-fed basin Somme River
2010/2/1
The Somme River Basin is located above a chalk aquifer and the discharge of the somme River is highly influenced by groundwater inflow (90% of river discharge is baseflow). In 2001, the Somme River Ba...
WATER TEMPERATURE VARIATIONS WITHIN A MAJOR RIVER SYSTEM
WATER TEMPERATURE VARIATIONS MAJOR RIVER SYSTEM
2009/10/29
This paper examines the relationships bctween river water temperature,
air temperature and stream flow measured continuously for one year at
four sites along the main stream of the river Tees in nor...
A Test of Snowmelt-Runoff Model for a Major River Basin in Western Himalayas
Snowmelt-Runoff Model Major River Basin Western Himalayas
2009/10/27
In the Snowmelt-Runoff Model (SRM), the estimate of discharge volume is
based on temperature condition in the form of degree days which are used to
melt the snowpack in the area of the basin covered...
This paper describes the spatial and temporal variability of strength in a typical
river-ice cover during the pre-breakup period affected by radiation decay.
Strength was determined using the boreho...
Relocation of Major Ions in Snow along the Tundra-Taiga Ecotone
Relocation of Major Ions Tundra-Taiga Ecotone
2009/10/26
The chemistry of seasonal snowcovers north of Inuvik, Northwest Territories,
Canada was stratified by biophysical landscape. In this region, deposition of
ions in winter occurs largely through the r...
Assessment of Spatial Variability of Major-Ion Concentrations and DEL Oxygen-18 Values in Surface Snow,Upper Fremont Glacier,Wyoming,U.S.A.
Spatial Variability Major-Ion Concentrations DEL Oxygen-18 Values
2009/10/26
One hundred samples were collected from the surface of the Upper Fremont
Glacier at equally spaced intervals defined by an 8,100 m 2 snow grid to assess
the significance of lateral variability in ma...
Release of Major Ions and Hydrogen Peroxide from Homogeneous,Melting Snow
Major Ions Hydrogen Peroxide Melting Snow
2009/10/26
We undertook two laboratory experiments to study the change of concentrations
and the preferential elution of major ions and hydrogen peroxide during melting
of a homogeneous snow pack. The elution ...
