Hydrochemische und hydrodynamische Modellrechnungen zur
Genese und Verbreitung von Tiefengrundwässern Unterfrankens
[Modelling of the Hydrogeochemical and Hydrodynamical Genesis and Distribution
of the Lower Franconia Deep Groundwater]
Keywords: Deep groundwater, Lower Franconia, thermodynamics, hydrodynamics
Abstract: This paper presents the hydrogeochemistry and hydrodynamic
of 27 different deep groundwater samples of the Lower Triassic and Zechstein
formations. Chemical and hydrodynamic parameters are quantified to characterize
typical processes within the deep hydrogeological regime of the Lower
Franconia. The different predominant mineral phases within these aquifers
are leading to typical concentrations of the water constituents within
each deep groundwater and mixing can be specified. Chemical reactions
between the groundwater and the local mineral phases, mixing and ion-exchange
processes are simulated stepwise to describe the genesis of a groundwater
near the water table of the Lower Triassic to a deep Zechstein water.
In a second phase of the study, physical-hydrodynamic parameters
are quantified, which are effective on the movement of the deep groundwaters.
Velocities, directions and densities of the deep groundwaters are calculated
with respect to the hydrostatic pressure. As a synthesis, all hydrogeochemical
and hydrodynamical results are used to construct an image of the whole
area and to delineate the flowlines and water circulation processes of
the deep groundwater system.

Physical Interpretation of the Discharge Coefficient
of an Aquifer, a, Maillet-Equation.
Elias Salameh & Hazim El-Naser
Keywords: MAILLET Equation, Discharge Coefficient, Jordan
Abstract: The MAILLET Equation Qt = Q0 * e - t describes the depletion
of a groundwater reservoir feeding a spring where the discharge coefficient,
, characterizes the spring discharge. Elaborations on the nature and functional
relationships of the other parameters included in are discussed and quantified.
was found to be a function of porosity, specific permeability, fluid density
and viscosity, extension of the aquifer and its geometrical configuration.
The relationship of with these parameters is applied to Nimra spring in
