The inclined shear restoration technique was used in this research as the primary
method to remove the effects of fault displacements. These displacements were resulted
from the impact of the NE-SW trending extensional forces. The inclined shear re
storation
technique was applied to the NE-SW trending seismic section (Inline A2157) along the
Elward Area, using 2D move software.
The vertical shear restoration technique was used as a complementary method to
remove the effects of folding associated with faulting, especially to formations under the
Base Upper Cretaceous Unconformity (BKU).
The inclined shear and the vertical shear restoration techniques contrib uted to build
many geological sections according to depth seismic section (Inline A 2157). These
sections showed the Tectonic setting of the study area from Upper Ordovician till current
time.
This research aimed to study the lengths effect of calculated filter- operator
by inverse filtering on the seismic data filtering. All programs used for
estimating the seismic signal, calculate the Filter- operator and performing the
Convolution w
ere written by author.
Some experiences about the influence of the length of filter-operator of the
outcomes of the inverse filtering were performed. The seismic data used in this
research were measured in two different areas in Syria, Alsaegh dam nearby
Sueda City and Rajo dam nearby Aleppo City. In addition, experiences are
carried out to test the effect of shortening the length of filter-operator.
The results showed that small length of filter-operators can be used by
inverse filtering without negative effect on the resolution of seismogram. In
addition we noticed that shortening the length of filter-operator depend on the
length of calculated filter-operator.
The aim of this research consists of the study the possibility of using the
geophysical methods to estimate the shallow geological structures and to show
the detailed lithological changes.
The geoelectric and georadar methods have been implemented
in an area at
Torgau city in Germany.
These methods have been applied on polluted aquiferes. Also geotechnical
study has been implemented in this area to compare the geophysical results.
The results show high resolution in both methods to estimate the
underground geological structures. By the integrated both methods, the
horizontal and vertical changes of these structures have been estimated with
high accuracy.
This research aimed to use the homomorphic deconvolution, applied for
processing seismologic and seismic Data, for processing the georadar Data. To
reach this aim, some changes in the algorithm of signal determination have
been carried out, in ord
er to match the properties of georadar data, I wrote a
computer Program, that include several steps, starting from transforming and
reading the field data, and ending by performing the inverse filtering.
The research shows the importance of the homomorphic deconvolution to
improve the resolution of Georadar-Record by raising the frequency content on
the field – georadar data. Using various field data measured at various
Locations by different Instruments, to test this method of deconvolution. The
results shows the efficiency of this method in differentiation the image of
georadar-Record, and consequently help the interpretation, which maximize
the applicability of the georadar data.
This research aimed to develop a new frequency filter to be used in
performing frequency filtering of seismic data. This research reviews
the filters used nowadays in frequency filtering and the principle of the
new filter, the method of obtaining
it, its properties compared to filters
used at present, its various forms of amplitude spectrum and the
corresponding filtering parameter.
