GROUNDWATER DEVELOPMENT AND ITS INFLUENCE ON THE WATER BALANCE
GROUNDWATER DEVELOPMENT INFLUENCE WATER BALANCE
2009/10/29
Lowering the head of an artesian aquifer in Zealand, Denmark by pumping
of groundwater is shown to affect the water balance.
Based on known amounts of groundwater being developed, the coefficient

Hot Groundwater Systems in Iceland Traced by Deuterium
Hot Groundwater Systems Iceland Deuterium
2009/10/29
This paper summarizes the result obtained for hydrothermal systems in Iceland,
by using deuterium and oxygen-18 as natural tracers.
The deuterium content of a single sample of a local cold spring or...

Groundwater Recharge Panjab State Tritium Tracer
2009/10/29
Vertical recharge to groundwater due to the 1972 monsoon plus supplemental
irrigation has been measured at 21 sites in the state of Panjab(1ndia) using tritigm
tracer. Average recharge is found to b...

2009/10/28
Recent investigations in the west coast region of Sweden has revealed the
occurrence of groundwaters with a pH of around 4 and, further, alarmingly
high concentrations of soluble aluminium. The reas...
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...
