37. Planos diretores municipais e planos de gestão das águas: uma análise comparada das cidades de Lisboa/PT e Porto Alegre/BR
Resumo A transformação do território está relacionada à ocupação do solo, o que reflete nos recursos hídricos. É necessário que os Planos Diretores Municipais (PDM) contemplem as diretrizes delineadas nos planos de água, levando à transformação sustentável do território e produzindo menos impacto nos rios. O objetivo deste trabalho foi anali

38. SPATIALIZATION OF THE ANNUAL MAXIMUM DAILY RAINFALL IN SOUTHEASTERN BRAZIL
ABSTRACT Extreme rainfall can lead to heavy damage and losses, such as landslides, floods and agricultural productivity as well as the loss of human and animal lives. To mitigate these losses, water resources management policies are needed, among other goals, to study and predict the frequency of such events in a given region to minimize their harmful effect

39. Phosphorus and thermotolerant coliforms’ loads in Brazilian watersheds with limited data: considerations on the integrated analysis of water quality and quantity
RESUMO Análises integradas dos aspectos qualitativos e quantitativos de ambientes aquáticos robustecem a tomada de decisão, que se vincula ao gerenciamento dos recursos hídricos e à promoção dos serviços ecossistêmicos. Contudo, as possíveis vantagens desta integração ainda esbarram em aspectos básicos, como elevadas incertezas devido ao monito

40. Using the pollutant load concept to assess water quality in an urban river: the case of Carahá River (Lages, Brazil)
Resumo O objetivo deste trabalho foi avaliar a qualidade da água do Rio Carahá no município de Lages (Brasil), utilizando o conceito de carga de poluentes e comparar a representação dos resultados com aquela expressa por meio do índice de qualidade da água. Para este estudo foram selecionados 13 pontos ao longo da calha do rio e realizadas 8 coletas d

41. Incertezas na simulação hidrológica em pequenas bacias por meio do modelo SWAT
ABSTRACT Hydrological modelling is one of the main tools in water resources management application. However, several factors make it difficult to extrapolate the estimated parameters in basins with large contribution areas to smaller basins. This research analysed the uncertainties of flow simulations in small basins. The methodological process involves the

42. Degradación de un efluente textil real asistida por Fe/PVA y materiales residuales magnéticos
ABSTRACT Organic compounds present on industrial wastes are mostly resistant to conventional biological and chemical treatments. Textile industry has presented several environmental problems mainly related to the use and management of water resources. It has a high consumption of potable and underground water in its processes. These wastewaters are one of th

43. 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

44. Energy balance partitioning and evapotranspiration from irrigated Muskmelon under Semi-Arid Conditions
ABSTRACT The Mossoró-Assu-Baraúna district, Rio Grande do Norte State (RN), is recognized by the intense production of horticulture, mainly muskmelon for export. However, this region is often devastated by intense droughts. Thus, the muskmelon production is predominantly under irrigated condition and, due to constant threat of water resources collapse on t

45. A STUDY OF THE IMPACT OF LAND USE AND OCCUPATION ON BASIN WATER QUALITY THROUGH MULTIVARIATE STATISTICS
ABSTRACT Without effective actions to improve environmental management, water resources tend to become scarce. Thus, this study aimed to understand the processes influencing the physical, chemical, and biological properties of the water due to land uses and occupation in the Ipê stream basin, in Ilha Solteira - SP (Brazil), regarding the dependence of the a

46. Ethnopedology of a Quilombola Community in Minas Gerais: Soils, Landscape, and Land Evaluation
ABSTRACT Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people

47. Hydrological Modeling of Tributaries of Cantareira System, Southeast Brazil, with the Swat Model
ABSTRACT The lack of hydrological data in Brazil is the main limitation for structuring hydrological models, which are able to assist water resources management. Therefore, studies are needed to evaluate the performance of models without on-site calibration. Within this context, the aim of this study was to calibrate the SWAT hydrological model for the Caman

48. COMPARISON OF METHODS FOR ESTIMATING REFERENCE EVAPOTRANSPIRATION: AN APPROACH TO THE MANAGEMENT OF WATER RESOURCES WITHIN AN EXPERIMENTAL BASIN IN THE BRAZILIAN CERRADO
ABSTRACT This study aimed to compare methods for estimating reference evapotranspiration using an experimental basin in the Brazilian Cerrado, for water management purposes. For that, we estimated daily reference evapotranspiration over a certain period (time series between 1982 and 2012) through different empirical methods. These methods consisted of Blaney
