Abstract
Joint inversion of different potentials improves subsurface model resolution.
In this paper seismic refraction and magnetotelluric data are used to under-
stand near subsurface features of Dholera, Gujarat, India. An extensive seis-
mic and magnetotelluric survey was carried out in Dholera in order to deli-
neate subsurface presence of aquifers. Ray Inversion for Near Surface Estima-
tion (RINSE) is used for inversion of Dholera seismic data. The inversion
output of seismic data is used as seed points for resistivity inversion of ano-
malies. Inversion of resistivity data is done using evolutionary programing
method which is also a type of genetic algorithm. Here the optimization is
done using four major steps, of evolutionary programing namely population
generation, fitness function, crossover and mutation. This paper also com-
pares the similarities between the natural and geophysical optimization. A
Low Velocity Layer is identified up to a depth of 11 m from seismic refraction
method. Three layers are identified after the interpretation of seismic and re-
sistivity data. The average thicknesses of Layers one and two are calculated as
3.558 and 6.533 respectively.

1. Introduction
Model resolution of subsurface features can be improved by joint inversion of
different geophysical potential data (Ammon et al., 1990). The study of joint in-
version can be categorized into two groups; first is joint inversion of datasets
which are sensitive to same physical parameters (Julia et al., 2000) and second
