1. Estimating design hydrographs at the basin scale: from event-based to continuous hydrological simulation
RESUMO Hidrogramas de projeto são amplamente utilizados em engenharia hidrológica. Típicas aplicações adotam métodos baseados em eventos (EB), utilizando modelos chuva-vazão para converter hietogramas de projeto em hidrogramas. Incertezas incluem a definição de condições antecedentes e a premissa de equivalência entre tempos de retorno da chuva

2. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

3. Implantação de tecnologias alternativas de saneamento como forma de garantir água de qualidade, quantidade e higiene no semiárido moçambicano : caso do distrito de Funhalouro
This work aimed at studying the hydrologic, hygiene and sanitation conditions in the district of Funhalouro, located in Inhambane province, Mozambique. This is a rural district characterized by semi-arid climate, with approximately 37,856 inhabitants, 8058 households and a population density of 2.78 inhabitants /km ². The water supply in the area of study i

4. Acumulação de elementos traço em organismos no estuário da Lagoa dos Patos / Acumulation of trace elements in organisms in the Patos Lagoon
Neste trabalho teores de elementos traço As, Cd, Cu, Cr, Fe, Mn, Pb, Ni e Zn foram determinados no camarão-rosa Farfantepenaeus paulensis, no cirripédio Balanus improvisus e no mexilhão Perna perna, coletados entre os anos de 2006 e 2010 no estuário da Lagoa dos Patos. Os resultados foram avaliados em função das variações hidrológicas interanuais o

5. A spatially distributed hydroeconomic model to assess the effects of drought on land use, farm profits, and agricultural employment.
In this paper a high-resolution linked hydroeconomic model is demonstrated for drought conditions in a Brazilian river basin. The economic model of agriculture includes 13 decision variables that can be optimized to maximize farmers' yearly net revenues. The economic model uses a multi-input multioutput nonlinear constant elasticity of substitution (CES) pro

6. Runoff inducement research for agriculture in very arid zones of Northeast Brazil.
The concept of runoff inducement for agricultural purposes in discussed in detail. Its implications to the North-East Braziliam conditions and necessity for additional research is explained. An exautive review of the research at various places in the world is included. The latest work being carried out at the Centro of Agricultural Research for Semi-Arid Tro

7. How much can the number of jabiru stork (Ciconiidae) nests vary due to change of flood extension in a large Neotropical floodplain?
The jabiru stork, Jabiru mycteria (Lichtenstein, 1819), a large, long-legged wading bird occurring in lowland wetlands from southern Mexico to northern Argentina, is considered endangered in a large portion of its distribution range. We conducted aerial surveys to estimate the number of jabiru active nests in the Brazilian Pantanal (140,000 km²) in Septembe

8. Simulação hidrológica de rios com grandes planícies de inundação
Besides understanding the current hydrologic behavior of a river and floodplain drainage system, it is important to be able to predict its future conditions in light of possible impacts due to anthropogenic activities and climate variability. Mathematical modeling is the ideal tool for this purpose. For large scale hydrologic systems, if the objective is to

9. Flavonoids of Lotus tenuis (Waldst. & Kit.) as markers of populations growing in soils of different saline and hydrologic conditions
Lotus tenuis Waldst. et Kit. (=Lotus glaber Mill.) é uma planta leguminosa muito difundida que cresce naturalmente em pastagens da Flooding Pampas, na Argentina. Uma das hipóteses para explicar a disseminação de L. tenuis nessa área, é a diferenciação de ecotipos. O objetivo deste trabalho foi investigar os compostos flavonoides presentes em populaç

10. Produtividade fitoplactÃnica e hidrologia no ecossistema recifal de Porto de Galinhas (Pernambuco- Brasil)
The Porto de Galinhas beach, located in the south coast of Pernambuco, Brazil, about 50 kilometers from Recife, has coral reef formations that form natural pools of extreme beauty, and thus, actually is undergoing an intense tourist activity, as one of the most visited beaches of Northeastern Brazil. The phytoplankton productivity and biomass and some hydrol

11. Ecologia e modelagem da distribuição dos sítios de nidificação do jacaré-açu (Melanosuchus niger) em uma área de várzea da Amazônia Central, Brasil
The black caiman, Melanosuchus niger, is primarily an Amazonian species, its largest populations are associated mainly with interior várzea areas, but its nesting ecology related with these hydrologic dynamic environments is still poorly understood. The objectives of this study were related to the generation of information on the nesting ecology of this spe
