Modelling of seawater intrusion
C. P. Kumar
I am grateful to the following members/experts for
their interesting/useful
observations/comments/suggestions on my report
"Modelling of a Coastal Aquifer using FEFLOW"
(available at ftp://ftp.wasy.de/FEFLOW/Goa.pdf ).
(1) Reinhard Zapata (Waterloo Hydrogeologic, Canada)
(2) Krishnaiah C. (India)
(3) S.V.N.Rao (Roorkee, India)
(4) V.V.S. Gurunadha Rao (Hyderabad, India)
(5) Michael Jorgensen (Australia)
I am prompted to seek further suggestions for the
following issues in modelling the seawater intrusion
in coastal aquifers.
(a) How to model the effect of salt pans on
groundwater in coastal areas?
(b) How to incorporate the evaporation from open water
surfaces (e.g. to define time-variant boundary
condition in case of rivers) and evaporation from
shallow groundwater table?
(c) How to model the effect of brackish water in
rivers (due to tidal backwater effect from sea) on
groundwater in coastal areas?
(d) How to develop correlation between resistivity
values and TDS and between resistivity values and
hydraulic conductivity.
(e) Suitability of Kriging, Akima and Inverse Distance
Weighting techniques for interpolation/regionalization
of different parameters/variables.
Any suggestions for the above will be helpful for
extension of this (or similar) study in future.
There is a small errata in the report - title of
figure 7 may be read as "Measured Values of Hydraulic
Conductivity (*10E-4 m/s)" - the multiplier was
missing.
Regards
Kumar
