1. TIME SERIES TRENDS OF STREAMFLOW AND RAINFALL IN THE SANTO ANTÔNIO RIVER BASIN, BRAZIL
ABSTRACT Detecting trends in streamflow and rainfall series can have great significance for proper water resource management. Thus, the objective of this study was to analyze the trends of historical streamflow and rainfall series using nonparametric statistical tests. A historical series of pluviometric and fluviometric gauges, which belong to the hydromete

2. Application of Markov chains to Standardized Precipitation Index (SPI) in São Francisco River Basin
Resumo Este trabalho objetivou avaliar períodos secos e chuvosos nas sub-regiões da Bacia Hidrográfica do Rio São Francisco (BHSF) utilizando o Índice de Precipitação Padronizado (SPI) e cadeias de Markov. Cada sub-região da BHSF possui características físicas e climáticas específicas, dessa forma foram utilizadas quatro estações pluviométrica

3. Development of an annual drought classification system based on drought severity indexes
Abstract: In order to characterize the occurrence and intensity of droughts in the Doce River Basin, as well as to develop a system for its classification, four different drought indexes were evaluated: Percent of Normal Precipitation (PNP), Deciles Method (DM), Rainfall Anomaly Index (RAI) and Standardized Precipitation Index (SPI). The indices were calcula

4. Simulation of Flow in the Capim River (PA) using the SWAT Model
ABSTRACT Flow in the Capim River watershed, located in the state of Pará, Brazil, was estimated using the Soil and Water Assessment Tool (SWAT) model in order to determine its use efficiency. The meteorological data (from 2000 to 2010) were collected from an automatic station located in the municipality of Paragominas. The pluviometric and fluviometric dat

5. CLIMATOLOGICAL WATER BALANCE WITH DATA ESTIMATED BY TROPICAL RAINFALL MEASURING MISSION FOR THE DOCE RIVER BASIN
ABSTRACT The Climatic Water Balance (CLIMWB) is very used in the climatic characterization and can also offer important contribution in the identification of the water demand for irrigation of a region. For this, reliable precipitation data with good spatial coverage is required. The Tropical Rainfall Measuring Mission satellite -TRMM-3B43-v7 is a partnershi

6. FUZZY INFERENCE SYSTEMS FOR MULTI-STEP AHEAD DAILY INFLOW FORECASTING
ABSTRACT This paper presents the evaluation of a daily inflow forecasting model using a tool that facilitates the analysis of mathematical models for hydroelectric plants. The model is based on a Fuzzy Inference System. An offline version of the Expectation Maximization algorithm is employed to adjust the model parameters. The tool integrates different inflo

7. Variabilidade climática e correlação entre TSM e vazão fluvial nos rios Amazonas e Negro / Climate variability of the Atlantic and Pacific oceans and flow of the rivers Amazonas and Negro
Climate variability is a complex system generated by the participation of various actors and their role in atmospheric dynamics, the Sea Surface Temperature(SST) plays a key role in influencing the several features of the climate indexes: Southern Hemisphere Cancel Index Mode (SAM), Southern Oscillation Index (SOI), El Nino / Southern Oscillation (ENSO), (TN

8. Diagnóstico hidrossedimentológico da Bacia do Rio Piquiri.
RESUMO: O conhecimento do comportamento hidrossedimentológico de uma bacia hidrográfica é fundamental para a adequada gestão e uso de seus recursos hídricos. Este traballho objetivou realizar, a partir dos dados hidrossedimentométricos da Bacia do Rio Piquiri, um diagnóstico sobre o seu comportamento hidrossedimentológico. Utilizando os dados fluviom

10. Qualidade ambiental de solos agrícolas da bacia do Rio Jaguari -São Paulo / ENVIRONMENTAL QUALITY OF AGRICULTURAL SOILS WITHIN THE JAGUARI RIVER BASIN - SÃO PAULO
Environmental impacts have occurred in various forms and intensities on soil, water and air media. Consequently, several countries have used legal criteria for soil protection, either by means of generic guiding values or through case-by-case risk assessment. The São Paulo Environmental Agency (CETESB) pioneered the publication of guiding values for soils a

12. ProposiÃÃo do uso de indicadores ambientais na avaliaÃÃo de desempenho de portos brasileiros
This work aims to demonstrate the possibility of inclusion of environmental indicators in the Current Port Performance System (SDP) used to evaluate the Brazilian ports. The environmental indicators are very important because of the scope of the environmental issue and, when used properly, can be effective in preventing impacts to the environment. In port ma
