Abstract

The use of hydrological models is widely used for information purposes of flow regimes in watersheds and to support when failures occur in measurements. This study aimed to calibrate a hydrologic model at Ibicuí da Armada watershed on southwest of Rio Grande do Sul State, in order to simulate their regime of daily flows for a period of 250 days ahead. Were used the WIN_IPH2 software for the simulation, adjusting optimization parameters through automatic calibration tests by objective functions, and subsequently checking it’s fit. The daily series were acquired from the database provided by Agência Nacional de Águas (ANA) and the Instituto Nacional de Meteorologia (INMET). The objective function that showed the best fit between the sample series was Mean Absolute Deviation function (MAR), proving to be the best to represent the Q90 and Q95. The employment created by WIN_IPH2 software combined with information constraints of flow regimes were quite useful for use in situations that require knowledge of water availability, thus contributing to the improvement of the management actions of water resources.

Ethical guidelines for journal publication

The REMOA 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. Reviews 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 referee 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.
