2. Heavy rainfall maps in Brazil to 5 year return period
Resumo Este estudo tem como objetivo criar mapas temáticos de chuvas intensas para o Brasil para durações de 5, 30, 60 e 120 minutos e período de retorno de 5 anos (T). As relações intensidade-duração-frequência (IDF) utilizadas foram compiladas a partir de estudos encontrados na literatura (798 locais) e estimadas para 4411 estações pluviométric

3. Puls method for events simulation in a lot scale bioretention device
RESUMO Biorretenção é uma técnica aplicada para tratar e reduzir o escoamento superficial gerado em áreas urbanas. Embora essas instalações apresentem processos complexos, um modelo simples com poucos parâmetros pode ser útil para seu projeto. Este artigo relata uma aplicação do método Puls como uma ferramenta quantitativa de simulação de biorr

4. SPATIAL, SEASONAL, AND TEMPORAL VARIATIONS IN RAINFALL AGGRESSIVENESS IN THE SOUTH OF BRAZIL
ABSTRACT The objective of this study is to evaluate spatial and temporal variations in rainfall aggressiveness in southern Brazil. A total of 181 rain gauge stations located in southern Brazil with rainfall time series from 1976 to 2015 were used. Seasonal and annual rainfall aggressiveness values measured according to the Modified Fournier Index (MFI) were

5. RAINFALL WATER QUALITY UNDER DIFFERENT FOREST STANDS
ABSTRACT The rainfall-forest canopy interaction can impact on the chemical and physical rain-water features and is expected that different forests will have different effects on throughfall rain-water quality parameters. This study aimed (i) to compare chemical and physical rain-water quality variables observed in both gross precipitation and throughfall mea

6. AplicaÃÃo do MÃtodo das Isozonas na ObtenÃÃo das EquaÃÃes IDF de Chuvas Intensas dos MunicÃpios de Juazeiro do Norte, Barbalha e Crato - CE / Isozones Method applied in the obtention of the heavy rainfall IDF equations of the Juazeiro do Norte, Barbalha and Crato (CE) municipalities.
The increase in use of urban and rural land demands knowledge on statistically treated data on intensity, duration and frequency of heavy rainfall, allowing better forecasting of peak flow rates - used in the design of drainage networks. The damage caused by flooding of urban and rural areas are only avoided by well dimensioned drainage works, resulting in c

7. Componentes do balanço de água em um Cambissolo cultivado com meloeiro irrigado por gotejamento, com e sem cobertura da superfície / Water balance components in an Inceptsol cropped with muskmelon drip irrigated, with and without covered surface
The knowledge about the soil water balance is essential to soil-water-plant system management. Thus, this research aimed to study the water balance components in an Inceptsol cropped with muskmelon under drip irrigation, with and without surface covering, in the county of Baraúna, Rio Grande do Norte State, Brazil (05º0448 S, 37º3700 W). In an experimenta

8. Evaluación de diferentes metodologías para la calibración de las estimaciones de precipitación cmorph sobre Sudamérica
This work describes the application of several methods for the calibration of precipitation estimates generated from passive microwave sensors using rain gauge observations. The experiments evaluated strategies for the development of an operational calibration process over Southeastern South America which can be easily applied to other regions. Results show

9. Interdecadal variability of precipitation in the Western Brazilian Amazon / Variabilidade interdecadal da precipitação na Amazonia Ocidental brasileira.
The present work focused on the interdecadal variability of precipitation in the Western Brazilian Amazon in order to help improve this knowledge and, in addition, to analyze, study and evaluate the low-frequency variability of the hydrological cycle in this region. To this end, we used data collected from conventional rain gauge stations 5, available at the

10. Efeito da cobertura do solo e de práticas de controle de erosão nas perdas de água e solo por escoamento superficial / Ground covering and practical erosion control effects in the water and soil losses by run-off
The main pollutants of water resources from agricultural areas are organic matter, sediments, nutrients and pesticides, carried out mainly by runoff from farming lands. Considering this fact, it is very important the development and application of technologies to reduce such undesirable residues discharges, that were analyzed in this study. The experiment wa

11. Comparison of precipitation and incident solar radiation products for South America: observed data and reanalysis / Comparação de produtos de precipitação e radiação solar incidente para a América do Sul: dados observados e reanálises
The goal of this study was to compare nine databases of precipitation and four databases of incident solar radiation of the South America, considering the meridional variation, and the variation across the main continental watersheds (Amazonas, Tocantins, São Francisco, Orinoco, Paraná/Prata, in addition to the main Patagônia basins) and across the main v

12. RELATION BETWEEN WEATHER TYPES, EXTREME PRECIPITATION EVENTS AND FLOODS IN THE URBAN SPACE OF SÃO SEPÉ RS / RELAÇÃO ENTRE TIPOS DE TEMPO, EVENTOS DE PRECIPITAÇÃO EXTREMA E INUNDAÇÕES NO ESPAÇO URBANO DE SÃO SEPÉ-RS
Among natural elements the climate assumes importance in that it relates to the ambient question of the cities. The choice for the channel of the Meteoric Impact, among the subsystems of Sistema Clima Urbano (SCU System Urban Climate), justified for the constant episodes of floods in the urban area of São Sepé. In this context, the work has as objective to
