1. Modeling and hydraulic performance evaluation of a dripper device coupled to a branched water distribution network
Resumo A irrigação é responsável por aproximadamente 70% do consumo de água doce do mundo e é um dos principais fatores por trás da crescente escassez de água global. As técnicas e sistemas de irrigação são extremamente diferenciadas e complexas. Neste contexto, as ferramentas de dinâmica de fluidos computacional (CFD) ganham relevância, permit

3. GAS EXCHANGE IN ‘POME’ BANANA PLANTS GROWN UNDER DIFFERENT IRRIGATION SYSTEMS
Abstract This study aimed to evaluate Pome type bananas grown under different irrigation systems. Seventy-two treatments were used in a factorial 3×2×12 scheme, where factors consisted of three irrigation systems (under-tree sprinkling, micro-sprinkling, and dripping), two cultivars (‘Prata-Anã‘ and ‘BRS Platina’), and twelve evaluation periods (m

4. SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS
Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variat

8. The design and evaluation of travelling gun irrigation systems: enrolador software
ABSTRACT Travelling gun irrigation systems offer great mobility and operation flexibility with a low investment cost per unit of irrigated area. However, the drawbacks include high operating pressure, low application efficiency, and high rainfall, runoff and erosion. Many of these problems can be minimized if the design and operation of travelling gun irriga

9. 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

11. Estudo da dinâmica da solução do solo para o manejo da fertirrigação por gotejamento na cultura do pimentão / Study of dynamics of soil solution for the drip fertigation management in culture of pepper
Among various systems, the drip irrigation has been increasingly used, mainly because of its greater efficiency in water use. This work aimed to study the dynamics of soil solution, characterizing the distribution and storage of nutrients in the soil solution, and their absorption by pepper through the management of drip fertigation with two flows rates. The

12. Evaluation of a computer model to simulate water table response to subirrigation.
The objective of this work was to evaluate the water flow computer model, WATABLE, using experimental field observations on water table management plots from a site located near Hastings, FL, USA. The experimental field had scale drainage systems with provisions for subirrigation with buried microirrigation and conventional seepage irrigation systems. Potato
