2. Optimal pressure management in water distribution networks through district metered area creation based on machine learning
RESUMO A gestão integrada dos sistemas de abastecimento de água com o uso eficiente dos recursos requer a otimização das operações. O agrupamento das redes de abastecimento de água em pequenas unidades, chamadas de distritos de medição (DMAs), é uma estratégia que permite o desenvolvimento de regras operacionais específicas, responsáveis por mel

3. Field Description and Identification of Diagnostic Qualifiers for Urban Soils in Brazil
ABSTRACT Human activities often alter soils found in urban areas. These alterations affect their environmental functions and potential for use. However, soils from urban areas in Brazil have not been surveyed and identified, which can pose a technical problem for the development of the city. Considering the importance of urban environments and their soils, t

4. Impacts of land-use change on southeast Amazonia basin streamflow
Resumo A Região Amazônica vem despertando interesse crescente da comunidade científica internacional devido às amplas possibilidades ambientais que suas densas florestas têm a oferecer no que diz respeito à regulação climática e recursos hídricos. Apesar dos muitos esforços de agências reguladoras de meio ambiente e centros de pesquisa, esta regi

5. Spatial and Temporal Potential Groundwater Recharge: the Case of the Doce River Basin, Brazil
ABSTRACT: Little is known about the groundwater recharge potential of weathered tropical catchments, where increasing water uptake is widespread to meet various water demands. This study aimed to estimate the volume of groundwater recharge of the Doce River Basin, Minas Gerais, Brazil. The BALSEQ model was applied to calculate the water balance over a period

6. Knowledge-based digital soil mapping for predicting soil properties in two representative watersheds
ABSTRACT: The estimation of soil physical and chemical properties at non-sampled areas is valuable information for land management, sustainability and water yield. This work aimed to model and map soil physical-chemical properties by means of knowledge-based digital soil mapping approach as a study case in two watersheds representative of different physiogra

7. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

8. ONE- AND TWO-DIMENSIONAL ECOHYDRAULIC MODELING OF FORMOSO RIVER (MG)
ABSTRACT The objective of this study was to compare ecohydrological simulations from a one-dimensional model (PHABSIM - Physical Habitat Simulation System) and a two-dimensional model (River2D) in order to indicate a reliable tool that could be used to determine public policies for the sustainable management of the water resources of the FormosoRiver basin(M

9. Ecohydrological modeling and environmental flow regime in the Formoso River, Minas Gerais State, Brazil
ABSTRACT This paper aimed at determining the environmental flow regime in a 1 km stretch of the Formoso River, MG, using River2D model. To carry out the ecohydrological modeling, the following information was used: bathymetry, physical and hydraulic features, and the Habitat Suitability Index for species of the Hypostomus auroguttatus. In the River2D, the We

10. Evaluation of the environmental sustainability of massive forestry fragments of the coastal plain and lower slopes of Bertioga (SP) / Avaliação da sustentabilidade ambiental dos fragmentos de maciços florestais da planície costeira e baixa encosta do município de Bertioga (SP)
The São Paulo coastal zone alternates extensive zones of great diversity of biotopes with others intensively degradated. These characteristics are observed in the municipality of Bertioga and its forest regions localized among Itaguaré and Guaratuba river basins. Due to their special characteristics these basins are denominated Bertioga System. The aim of

11. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr

12. Balanço hídrico e energético de um sistema predial de aproveitamento de água de chuva / Water and energy balance of a rainwater harvesting system for a building gutter
The use of rainwater as an alternative source of water supply is a practice on the rise, mainly for its importance in conservation of water resources. However, the user often ignores the energy that this system may require, and depending on its design, can be considered a relevant factor in its application. The conceptions and components of a rainwater harve
