Resumo: | |||||||||||||||||||||||||||||||||||||
The surface of the earth is formed by geological processes that originate
the rocks, as well as for natural processes of degradation and erosion. The
erosion destroys the soil structures and the transport of sediments is made by the
action of the rain water, wind, gravity and, in some cases, ice. The origin and
evolution of sedimentary basins, amongst other phenomena, are studied by the
sedimentary geology, which deals with the analysis of physical, chemical and
biological processes that act directly on earth surface since its origin until the
current days. Nowadays, the use of runoff - erosion models that analyze
processes such as detachment of particles and transport and deposition of
sediment in drainage basins is every time more frequent. The use of these
models demonstrates that, for relatively small scales and not very extensive
areas, relief changes are directly related to tectonic processes. On the other
hand, landscape evolution models and associated weathering, erosion and
deposition with parameterization for regional or continental spatial scales and
large time scales (more than 10(5) years), must be developed to adequately couple
tectonics and geomorphology. Is presented in this work a computational model to
analyze the landscape evolution in hydrographic basins, considering small and
large scales, as well as evaluate the production of sediment resultant of the
erosive process. The algorithm is written in the programming language C++ and
considers the simulation of different scenes, that include tectonics, hillslope
processes (diffusion and landslides) and bedrock incision, giving particular
attention to the channel network evolution. For the analysis process the program
offers the visualization of different 3D surfaces: sediment distribution, drainage
network, topographical relieves etc.
