The 3-Reservoirs problem was solved using the Turbo Pascal language Version 6.0. This problem, better known as the “Bélanger’s problem” involves the determination of the unknown pressure head at the junction of the three ...

A soil moisture model (SIMBA) was validated for irrigated and non-irrigated dry beans in Paraná, Brazil. The model presented an excellent performance for prediction of soil moisture and realistically simulated the remaining ...

A set of 67 data of entrance resistance was used to find the more adequate value to evaluation the performance of subsurface drain of clay pipes. The results presented high variability and log-normal distribution. The ...

Estudies developed by many authors shows that it is possible evaluate the irrigation water quality empirically, turning it agile, simple and cheaper. This paper analysed and compared some of its equations developed for ...

This research evaluate the representability of the soil fraction sample (2,0-6,35 mm) utilized in the aggregate stability determination and its size class distribution. It was observed that there is no correlation between ...

In this study, the objetive was to determine the moisture redistribuition in field on an Yellow-Red Podzolic Soil, cultivated with banana, observing the wetting front evolution through the time and also a moisture meter ...

The aim of this work was to delimit and describe spatial and temporal homogeneous, relative to rainfall, in the State of Paraíba, Brazil. 157 hydrometeorological units were considered, of INMET stations and SUDENE ...

To study irrigation quality of a microsplinkles, an experimental set up was alone at the “Fazenda Experimental da UFC ” , at Pentecoste-Ce, Brazil. Comprising a 6m x 12m spacing, 3 different rises heights and 3 average ...

The region of Jales is one of the most important table grape producer in the state of São Paulo, Brazil. All the cultivated area is irrigated. This work had the purpose to provide basic informations to a rational water ...

In a field test was study the effect of irrigation with marginal waters quality (salinities) about melon yield (var. yellow), conduced in drip irrigation system. There was utilize six (6) levels of salinity (EC = 0.46; ...
