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...
The environmental isotope oxygen-18 was used as a tracer to separate stream
discharge into flows originating from groundwater and fresh meltwater. Two,
mainly forested, watersheds (areas 6.6 and 4.0...

The Astdalen catchment (373 km2) represents largely a natural ecosystem,
typical for the higher central and southern parts of the Scandinavian Peninsula.
It is underlain by fractured sedimentary roc...
Operational Spring Time Forecasting Difficulties and Improvements
Operational Time Forecasting Difficulties Improvements
2009/10/27
A modified version of HBV-3 model has been used since 1981 for operational
spring-time forecasting in Finland. This model is ready now for eleven river
basins ranging from 500 to 30,000 km2. From th...

Spring Discharge Aquifer Characteristics Sandy Till Area
2009/10/27
Spring discharge and groundwater levels were used to study groundwater outflow
recessions, groundwater reservoir sizes, water yielding properties and
saturated hydraulic conductivities in a sandy ti...
Acidification of Shallow Groundwaters During the Spring Melt Period
Acidification Shallow Groundwaters Spring Melt Period
2009/10/27
During the spring of 1985 shallow recharge area groundwaters at depths less
than one metre in the Turkey Lakes watershed were observed to undergo short
term (1 to 10 days) pH and alkalinity depressi...
Field Investigation of the Thermal Bar in Lake Ladoga,Spring 1991
Field Investigation Thermal Bar Lake Ladoga
2009/10/26
The thermal bar in Lake Ladoga was studied during one week in May 1991.
Temperature and current velocity distributions were measured. The movement
of the thermal bar and the horizontal heat transpor...
Spring Circulation Associated with the Thermal Bar in Large Temperate Lakes
Spring Circulation Thermal Bar Large Temperate Lakes
2009/10/26
The overall circulation pattern in spring is rather specific as density-induced
currents may be of significance. The density-driven circulation perpendicular to
the shore can be described as consist...
The formation mechanisms and regional characteristics of spring water temperature on the northern foot of Mt. Asama
Mt. Asama Spring water temperature Volcanic activity Wind-hole circulation Groundwater flow system
2009/7/14
It can be recognized that water temperature of springs distributed on the northern foot of Mt. Asama has remarkable regional variations. The purposes of this study are to discuss the various formation...
Has spring snowpack declined in the Washington Cascades?
snow water equivalent Washington Cascades snowpack declined
2009/4/28
Our best estimates of 1 April snow water equivalent (SWE) in the Cascade Mountains of Washington State indicate a substantial (roughly 15–35%) decline from mid-century to 2006, with larger declines at...
Mixing and transport of water in a karst catchment：a case study from precipitation via seepage to the spring
karst catchment seepage spring
2009/4/28
One of the best-known and largest karst areas in Germany, the Blautopf Catchment, offers unique access to waters of the unsaturated zone through a large cave system. It was investigated with stable is...
