THE INFLUENCE OF USE AND LAND COVER IN THE WATER QUALITY PARAMETERS IN THE RIVER BASIN ABAÚNA IN GETÚLIO VARGAS, RS
Keywords:quatic environment. Terrestrial environment. Integration
The water quality of a river basin dependent on numerous factors, whether natural or anthropogenic. Thus, this research aims to analyze the water quality parameters and the influence of land use and land cover in the watershed of Abaúna Rio, Brazil. The methodology made it possible to analyze the aquatic and terrestrial environment so as to achieve integration between the different uses and land cover and water parameters. For this, we used the satellite image Landsat 8, for that survey land use and land cover. The water parameters were: total suspended solids (TSS), water temperature (Temp.); hydrogen potential (pH); dissolved oxygen (DO), turbidity and total coliforms. From the integrated assessment of aquatic and terrestrial environment, it was found that water most collection points falls within the rules of CONAMA, but not for human consumption and it became clear that the uses are not in accordance with the rules of Federal Forest code. Therefore, the uses are interfering in water quality by altering the physical, chemical and bacteriological. For the improvement of the entire watershed water quality it is important to implement the use of alternative and land cover for the preservation and restoration of riparian forest.

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.
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.
