The strands are configured as one of the main elements of the landscape, when viewed in a short time, show up with static appearance, however they are continually being worked by erosive or depositional processes. The main objective is to contribute to the understanding of the profile conformation and shape of the slopes up the water-physical parameters of soil cover on slopes situated on lithologies of Santa Maria Formation, in Santa Maria, RS. According to the objectives of the work, it was used as a theoretical and methodological basis the proposal structural analysis of soil cover, which allowed the understanding of the dynamics of soil cover and the relationship with other landscape elements. After analysis of the results, there was obtained the following physical-hydric behavior of horizons diagnoses of the soil profile, where it was identified the process of translocation of clay from superficial diagnostic horizons A, AE, E and EB for subsurface BE and B, these being more durable, impermeable horizons, contributing to turn convex the top of the slope. Already at the slope base, the concave shape is due to regressive erosion of less resistant horizons and the organization thereof, commanded by surface and subsurface water circulation.Downloads

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
