1. Variabilidade espacial da uniformidade da lÃmina de Ãgua aplicada por sistemas fixos de irrigaÃÃo por aspersÃo / Spatial variability of water level uniformity applied by fixed sprinkler irrigation systems
Water application uniformity is an important factor to be considered in the evaluation of sprinkler irrigation systems. The uniformity depends on the type of sprinkler and its operational conditions, the display and space among the sprinklers on the field, and also the wind speed and direction during the water applying period. This work contributes to develo

2. COMPARAÇÃO ENTRE DOIS SISTEMAS HIDRÁULICOS DE MEDIÇÃO DE AGUA DE IRRIGAÇÃO DE ARROZ / COMPARISON BETWEEN TWO HIDRAULICS SYSTEMS OF MEASUREMENT OF RICE IRRIGATION WATER
The irrigated farm crops are the main users of water. With this, in places where there is a water shortage to attend all sorts of use, this kind of activity is characterized like as a potentially conflicting, once that to produce one hectare of rice, are necessary thousands cubic meters of water. To work out this conflict, many actions are been developed, as

3. A longevidade do Aedes aegypti durante a estação chuvosa no município de Fortaleza. / The longevity of Aedes aegypti during the rainy season in Fortaleza.
Dengue fever constitutes a serious world health problem and the state of Ceará has been showing dengue fever since the year of 1986. In Fortaleza city, the capital of the state of Ceará it the was registered a great number of dengue epidemics, highlighting that the incidence of dengue fever is bigger during the rainy season rather than the non-rainy season

4. Comportamento hidráulico de um perfil de solo não saturado de Aparecida de Goiânia-GO / Hydraulic behavior of an unsaturated soil profile of Aparecida de Goiania-GO
The hydraulic behavior of a tropical and unsaturated soil profile of Aparecida de Goiânia-GO is presented. The main objective of this research was to contribute to the understanding of hydraulic properties of a tropical soil, with special emphasis on the soil-water characteristic curves and its hysteresis. The research work done was divided into two main pa

5. Validação experimental de metodologias para quantificação contínua de vazão no Ribeirão da Onça / Experimental validation of methodologies for continuous measurement of flow in the Ribeirão da Onça basin
Desde 2004, o grupo de estudos do Laboratório de Hidráulica Computacional (LHC) estuda as taxas de recargas hidráulicas do Aquifero Guarani, na Bacia do Ribeirão da Onça. Entretanto, não havia se estudado a quantificação do escoamento superficial. Para sanar esta deficiência, este trabalho visou analisar as metodologias de estimativa de vazão com q

6. Water under measurement evaluation at one-family residential buildings : a case of low income units located in Campinas, Brazil / Aplicação da submedição de agua em edificações residenciais unifamiliares : o caso das unidades de interesse social localizadas em Campinas
Water consumption under measurement can represents about 8 to 23% of the produced water in Brazil. It can be caused by oversized meters or others external cause. Low flows are common in cold water systems with a reservoir controlled by conventional ball cock faucets. This work presents a study case developed in 22 low-income houses located in Campinas, Sao P

7. MEASURER OF PROPORTIONAL OUTFLOW FOR THE QUANTIFICATION OF THE WATER CONSUMPTION IN THE IRRIGATION / MEDIDOR DE VAZÃO PROPORCIONAL PARA A QUANTIFICAÇÃO DO CONSUMO DE ÁGUA NA IRRIGAÇÃO
The present work had for objective to develop a simple process, with low cost and enough precise for its use in irrigation systems. The measurer consists of a secondary canalization provided with a hydrometer of low outflow installed in parallel with a singularity capable to provoke a pressure difference enters the extreme points of the device. The distingui

8. Análise da micromedição do volume de água potável domiciliar e sua influência no cálculo das perdas no sistema de distribuição / Micro-measurement of domestic drinking water volume and its influence on the calculation of losses in the distribution system
The accelerated degradation of natural hydric resources, along with the increasing demand for drinking water, urge for programs which deal with the losses of this essential good, and that are essential for environmental managers. This work is inserted in this context, with the objective of evaluating the magnitude of the measurement error of the hydrometers

10. Sedimentación de partículas con distribución de tamaño fractal
Since several years the fractal fragmentation model has attracted the attention of researchers, as a logic way to describe and interprete observed particle size distributions. Textural analysis has shown to be very important because of its usefulness in the dignosis and inferences about soil functioning and use. Most popular methods of textural analysis empl

11. Estimativa da recarga em uma unidade detrítica de uma microbacia do rio Piranga (MG) / Estimate of the recharge in a detrítica unit of a microbasin of the river Piranga (MG)
The present work has the aim of estimate the recharge for a phreatic granular aquifer located at Piranga river drainage basin, at Paula Cândido (MG) municipality area. Three techniques were used in order to achieve this recharge: ground-water inventory, water level variation and ground-water discharge measurement. The water level variation evaluation was ba
