O Sistema Aquífero Serra Geral (SASG) é composto por aquíferos fraturados associados às estruturas existentes nas rochas vulcânicas, sendo um sistema heterogêneo e anisotrópico. Por esse motivo, os métodos de Cooper & Jacob e Theis costumam não ser eficazes em traduzir as descontinuidades do meio e podem levar a avaliações incertas. A utilização de outros métodos, como os de Warren & Root e de Moench aplicados para aquíferos de dupla porosidade, podem representar uma alternativa para a avaliação desse tipo de aquífero. Dentro desse contexto, o objetivo do estudo foi determinar a eficiência do uso de modelos de dupla porosidade na avaliação de aquíferos fraturados, comparando com os modelos clássicos, através da análise dos ajustes dos dados teóricos aos dados de rebaixamento obtidos em campo. Os dados analisados provêm de testes de bombeamento com poços de observação realizados em uma bacia hidrográfica no município de Caxias do Sul – RS, na qual há a ocorrência do SASG. Os ajustes obtidos através dos métodos de dupla porosidade revelaram que estes apresentam boa adequabilidade no ajuste das curvas de rebaixamento podendo ser empregados para análise de parâmetros hidrodinâmicos de aquíferos fraturados, tal como o SASG. Destaca-se o método de Moench, cujos erros foram 90% inferiores do que os apresentados pelos métodos clássicos, mostrando que estes últimos são menos eficazes na avaliação do comportamento hidrodinâmico da água em meios heterogêneos e anisotrópicos.
The search for a balance between the needs of human beings, in the economic and social spheres, and the preservation of natural resources is indispensable. To this end, it is essential to elaborate regulatory policies, a role that the United Nations (UN) has been demonstrating efforts through the proposition of global political commitments, where the 2030 Agenda stands out, composed of 17 Sustainable Development Goals (SDGs). Another important concept is that of Corporate Social Responsibility, where companies started to adopt a broader business vision, in addition to the obligations required by law, taking responsibility for their impact on society in general. From this, organizational changes also occurred in the field of education, as educational institutions, increasingly competitive, began to include sustainability metrics. The Social Balance has become the tool for disclosing the economic and social performance of organizations. Thus, the objective of this work was to carry out an analysis of the Social Balance report of a Higher Education Institution maintainer in relation to the UN Sustainable Development Goals, focusing on the opportunities for improvements yet to be implemented. The object of study was the University of Caxias do Sul Foundation (FUCS). Data collection took place through the publication of the FUCS Social Balance Report with a base date of 2015, where the reported actions were compared with the 17 UN SDGs. It was observed that FUCS is an institution that presents a great initiative regarding actions and projects linked to the SDGs, but lack effective actions aimed at objectives 1, 2, 5 to 7, 11 to 15 and 17, where it has a smaller number of these when compared to the other objectives. Each objective has several specific goals, which require more comprehensive, continuous, systematic and collective efforts with other entities to become effective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
