Application of Chemical Mass Balance to Water Quality Data of Malaprabha River
Mass balance Salinity advection base flow
2015/8/6
Mass balance calculations carried out for Na, K, Ca, Mg, Cl, SO4 and HCO3 for the study area showed that the major source of contamination is through non-point sources. It is also observed that the ri...

Physical and chemical consequences of artificially deepened thermocline in a small humic lake – a paired whole-lake climate change experiment
Physical chemical consequences artificially deepened thermocline
2010/12/22
Climate change with higher air temperatures and changes in cloud cover, radiation and wind speed alters the heat balance and stratification patterns of lakes. A paired whole-lake thermocline manipulat...

interest has been focused upon the fate and e...
Seasonal Fluctuations of Physical and Chemical Parameters of a Weir Basin in a Regulated West Norwegian River
Seasonal Fluctuations Physical Chemical Parameters Weir Basin
2009/10/28
Both before (1967-69) and after (1976-78) the regulation of the river Ekso in
western Norway, physical and chemical analyses were made of the river water.
After the regulation water samples for chem...
Representativeness of Chemical Analysis of Groundwater
Representativeness Chemical Analysis Groundwater
2009/10/28
This paper raises the question of the representativeness of a single chemical
analysis of groundwater. This is undertaken with the knowledge of the variations
in chemical constituents obtained in th...

Mixing Effects Carbonate Dissolving Waters 13C/12C Compositions
2009/10/27
Seasonal variations in chemistry and r1atios o f total inorganic carbon of
carbonate dissolving waters are considered in the frame-work of a simplified
approach dealing explicitly with major ionic s...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
On the Physico-Chemical Basis for the Capillary Barrier Effect
Physico-Chemical Basis Capillary Barrier Effect
2009/10/27
The capillary barrier concept, using fine and coarse soil layers to reduce water
infiltration into piles of hazardous wastes, is investigated theoretically. A detailed
account of the hydrological an...
