1. Managing agricultural phosphorus to minimize water quality impacts
ABSTRACT Eutrophication of surface waters remains a major use-impairment in many countries, which, in fresh waters, is accelerated by phosphorus (P) inputs from both point (e.g., municipal waste water treatment plants) and nonpoint sources (e.g., urban and agricultural runoff). As point sources tend to be easier to identify and control, greater attention has

2. Avaliação da qualidade da água de chuva e de um sistema filtro-vala-trincheira de infiltração no tratamento do escoamento superficial direto predial em escala real em São Carlos SP / Evaluation of rainfall water quality and a filter-swaleinfiltration trenches system in the treatment of the building direct runoff in real scale in são carlos sp
Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns th

3. Fluxos hídricos na microbacia do córrego do Queixada no município de Jataí / Water flows in the stream watershed queixada in the city of Jataí (Go)
The diagnosis of hydrological flow and the rainfall interception by vegetation is justified by the need for knowing the influence of these elements in river basins, where weeds and appropriate use of land are responsible for maintaining the quality of the slopes, avoiding erosion, soil loss, silting of waterways and induces the maintenance of groundwater res

5. Diagnóstico ambiental urbano da cidade de Novo Airão - Amazonas
Most of Brazils municipalities are suffering environmental impacts. This situation is worse when we talk about small towns, where the framework for environmental policies is still precarious. In this ambit, when it comes to the urban planning of cities in the Brazilian Amazon, the situation is different, because the cities in the countrys northern region usu

6. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning

7. The effects of urbanization and runoff water quality in the Mogi / O estudo do efeito da urbanização e da ocupação urbana no escoamento da microbacia do córrego Mogi em Uberlândia - MG
Este trabalho avaliou o efeito da urbanização e a ocupação do solo na qualidade do escoamento superficial do córrego Mogi, em Uberlândia - MG, por meio da coleta de amostras de água obtidas no momento da chuva e em períodos secos. A coleta de amostras foi realizada na sarjeta do sistema de drenagem, na área de preservação permanente e em vários p

8. Geotechnology applied to the sub-basin of the river and its environmental relationships Piauitinga / Geotecnologia aplicada à sub-bacia hidrográfica do Rio Piauitinga e suas relações ambientais
The complexity and challenges of using the sub-basin of the river Piauitinga were approached from the choice of methodology geosystem suited for small river basins based on diagnosis of geoenvironmental and socioeconomic conditions. The area under study includes the municipalities Lagarto, Boquim, Salgado and Estancia and making the area of 411.98 square km

9. Quantification of impervious surfaces in urban areas using remote sensing techniques / Quantificação das superfícies impermeáveis em áreas urbanas por meio de sensoriamento remoto
Impervious surface coverage growth has direct consequences in quantity and quality of stormwater runoff, such as floods and nonpoint source pollution. The quantification of basins imperviousness makes possible to use it as a water quality indicator for urban areas and as an important planning and managing instrument in the urban water resources management sy

11. Human Adenoviruses and Coliphages in Urban Runoff-Impacted Coastal Waters of Southern California
A nested-PCR method was used to detect the occurrence of human adenovirus in coastal waters of Southern California. Twenty- to forty-liter water samples were collected from 12 beach locations from Malibu to the border of Mexico between February and March 1999. All sampling sites were located at mouths of major rivers and creeks. Two ultrafiltration concentra
