Geomorphology: concepts and recent technologies

Teresa Gallotti Florenzano

The relief area of the earth surface, object of the Geomorphology, is an important factor in the human’s life. It influences since the construction of a house, the management of the agriculture, the choice of the place for tourism, to the implantation of great engineering works and the strategic planning in war situations.

Because of the relief area being highlighted in satellite images, the Geomorphology is one of the sciences that benefits most from the technology of the remote sensing. This technology enables our spectral, spatial and temporal vision of the terrestrial environments.

Innovating, this book details the compartments of fluvial, coast and karst reliefs, among others; the tectonic processes and the dynamics which shape the terrestrial surface, such as mass wasting.

Throughout the 10 chapters, the reader will have the opportunity to perceive the reason why Geomorphology has become an indispensable base to the environmental planning and studies.
