Resumo: | ||||||||
Sedimentary Geology deals with the study of the physical,
chemical and biological processes operating in the surface
of the Earth, not only in the present days, but also along
all History. Therefore, it can be applied in miscellaneous
fields, as, for example, in the study of fossils fuels
formation. One of the main focus of sedimentary geology
inhabits in determining the parameters and processes for
which the sedimentary basins are filled. In this work the
development of a numerical simulator of sedimentation 3D,
called STENO is presented, with emphasises the depositary
processes in platform, slope, and basin environments. The
algorithm of the simulator is based on the formulated
quantitative concepts for Sequence Stratigraphy, as
mechanisms of primary control of the architecture of
sedimentary stratus, and in a numerical analysis for
simulation of the 2D steady-state flow of a incompressible
fluid, not viscous, in function of the bathymetry of the
region represented by one regular grid defined by the user.
The velocity field calculated from boundary conditions
(sediment aport velocity and for field stream velocity) it
is used to determine the direction of draining of the
sediments (streamlines). The algorithm of STENO is
innovative because it considers that the sediments are
carried hydrodynamicsly, that is, in direction x and y they
are carried following streamlines and in direction z. The
movement/deposition of sediments is controlled by an angle
of stability of each lithology fraction (sand, silte or
clay) and by the volume of the available space for
accommodation in each one of the columns formed in the
cells of the discretized model.
