Today, the importance of energy cost and efficiency is gradually increase. The decrease in drinking water and agricultural water resources, increases the interest in drip irrigation systems in agricultural irrigation. Environmentally friendly photovoltaic drip irrigation systems (PVDIS) are the appropriate solution in regions where there is no electricity distribution network, where it is far away, or where power cuts are frequently. This study is carried out in the Fergana Valley of Uzbekistan. Regional climate data obtained from Climwat 2.0 software are processed in Cropwat 8.0 software. Crops that are both the source of livelihood of the people of the region and that can be used in this study have been determined. Annual and daily water needs are analyzed so that these crops are irrigated every seven days. A system is designed by taking the data of the crop with the highest water requirement as a reference. The drip irrigation system is set up in a PVsyst 7.1.7 simulation environment to pump 114.24 m3 of water daily from a 5-meter-deep river with a 1.8 kW photovoltaic system. The efficiency of the system is 58.7% and the efficiency of the pump is 34.5%. Crop water need is met at the rate of 98.87%. It is predicted that the designed and analyzed PVDIS will provide efficiency in energy and water resources.

Gravity fed drip irrigation techniques have been used in the small agricultural production as an advanced water saving irrigation method in recent times. However advantageous this method, there are still some difficulties in projecting the efficiency of such systems. Most especially, feasibility study of gravity drip irrigation for small scale farmers is very important in order to set up an efficient irrigation system. This study is focused to test the feasibility of the drip irrigation the experiment was run and Uniformity co-efficient and Distribution uniformity. In the study, the discharge of emitters at 1.0 m and 0.5 m emitter spacing and 1.0 m lateral spacing and for four irrigation durations (15 minutes, 30 minutes, 60 minutes and 120 minutes) was measured. The results clearly indicates that the selected emitters of 4 LPH rated discharge and 2.0 kg/cm2 pressure when used under gravity drip irrigation and at about 0.5-0.8 kg/cm2 pressure, discharges between 1.8-2.5 LPH. 6. The gravity drip irrigation can meet the water requirement of vegetable crops with acceptable UC and DU and can be a better solution for small scale farmers of the region in order to save the scarce fresh water resources.

[email protected]  1 RESUMO A irrigação localizada envolve os sistemas onde a água é aplicada diretamente sobre a região da raiz, em pequenas intensidades, mas com alta freqüência, a fim de manter a umidade do solo na zona radicular próxima à capacidade de campo, sendo de grande importância no cenário agrícola brasileiro, com aplicações voltadas principalmente para a fruticultura, horticultura e fertirrigação. Os sistemas de irrigação localizada de alta frequência são os mais afetados pela obstrução dos emissores decorrente da contaminação da água. Este trabalho objetivou avaliar a obstrução de emissores em um sistema de irrigação por gotejamento usado na cultura da uva por 5 anos, com fertirrigação, utilizando água salina de poço profundo, afim de apontar possíveis causas e sugerir soluções que permitam o uso otimizado da água de irrigação. Como referência, os tubos gotejadores inicialmente foram submetidos a 360 h de irrigação com água do Serviço Autônomo de Água e Esgoto de Juazeiro-BA (SAAE) e posteriormente com água do Rio São Francisco.  O trabalho foi desenvolvido no Laboratório de Irrigação, no Campus de Juazeiro/BA, da UNIVASF. A estatística foi à descritiva, por medidas de tendência central e por medidas de dispersão de dados. Como principais resultados têm-se que os emissores com cinco anos de uso na fertirrigação, apresentaram inicialmente um grau de entupimento de 16,5%, bem superior se comparado com o mesmo tubo gotejador novo, em torno de 7%; com um aumento nos valores para 18% e 11%, respectivamente. Foi verificado que a água salina causou uma obstrução parcial maior que a água tratada do abastecimento. PALAVRAS CHAVE: grau de entupimento, água salina, uniformidade de aplicação.  NASCIMENTO, R.

For ecological gardening, it is necessary to develop agricultural landscapes, which are currently not used effectively enough in mountainous areas and are not adapted for the production of eco-products, except for hay on pastures. Drip irrigation systems allow you to grow orchards and vineyards on the slopes of mountains and areas with high slopes. The source of irrigation for orchards is usually mountain rivers, which have an unstable water regime due to flood events, which is a problem for the development of ecological gardening and viticulture. Designed water intake structure on the White river for drip irrigation systems, which in a complex hydrological regime source of irrigation ensures the production of water for irrigation of crops, and allows at minimum levels to provide the necessary water supply for irrigation of crops in the highlands of the North Caucasus. The design for extracting irrigation water includes perforated polyethylene pipes with a flushing device located in a trench in the backfill of the filter. Water purified from large deposits flows by gravity into the receiving well and is then sent to an additional treatment system. This approach to water extraction provides a guaranteed irrigation regime for the garden of fruit crops.

Drip irrigation system has become one of the most common irrigation systems especially in arid and semi-arid regions due to its advantages in saving water. One of the most essential considerations in designing these systems is the dimensions of the wetted soil volume under emitters. These dimensions are significant in choosing the proper emitter spacing along the laterals and the suitable distance between laterals. In this study, a modified empirical equations for estimating the horizontal and vertical extend of the wetted zone under surface emitters were suggested. Data from published papers includes different conditions of soil properties and emitter discharge were used in deriving the empirical model using the nonlinear regression. The developed model has high value for coefficient of determination, R2. The results from the developed model were compared with results of other empirical models derived by other researchers. Some statistical criteria were used to evaluate the model performance which are the mean error ME, root mean square error RMSE, and model efficiency EF. The results revealed that the modified model showed good performance in predicting the wetted zone dimensions and it can be used in design and management of drip irrigation systems.

The perturbation in hydraulic networks for irrigation systems is often created when sudden changes in flow rates occur in the pipes. This is essentially due to the manipulation of hydrants and depends mainly on the gate closure time. Such a perturbation may lead to a significant pressure variation that may cause a pipe breakage. In a recent study, computer code simulating unsteady flow in pressurized irrigation systems—generated by the farmers’ behavior—was developed and the obtained results led to the introduction of an indicator called the relative pressure variation (RPV) to evaluate the pressure variation occurring into the system, with respect to the steady-state pressure. In the present study, two indicators have been set up: The hydrant risk indicator (HRI), defined as the ratio between the participation of the hydrant in the riskiest configurations and its total number of participations; and the relative pressure exceedance (RPE), which provides the variation of the unsteady state pressure with respect to the nominal pressure. The two indicators could help managers better understand the network behavior with respect to the perturbation by defining the riskiest hydrants and the potentially affected pipes. The present study was applied to an on-demand pressurized irrigation system in Southern Italy.

This work aimed to evaluate the performance of a drip irrigation system with photovoltaic energy directly connected to the water pumping system through the irrigation uniformity coefficients using the statistical quality control, with the control chart of Shewhart. The experiment was conducted at the State University of West Parana (UNIOESTE), campus of Cascavel, in the Project CASA (Center of Alternative Energy System Analysis), during six days of open sky. The irrigation system contained four lines with 18 drippers each, collecting the flow of each dripper for five minutes, along with the parameters of temperature and solar radiation. In the energy part, the current and the voltage generated by the panel were analyzed. The main results allowed to evaluate that the flows of the drippers showed changes directly proportional to the decrease or increase of the radiation. Even with the changes in radiation levels during the collection period, the system obtained excellent process capability according to the analyzes of the distribution uniformities. It was also concluded that there was a significant relationship between the coefficients (CUC, DUC and CV) with the process capacity of the flow data. The control plot was adequate to diagnose the treatments. Statistical control proved to be effective for the determination of process variability, thus recommending the use of a drip irrigation system with a solar photovoltaic system directly connected to the pump on open sky days with few clouds due to the lower variability in relation to the graph of control and greater uniformity of water distribution.

Entre as atividades que necessitam de água, a irrigação é considerada a mais exigente em termos de volume. O objetivo deste estudo foi identificar e quantificar a distribuição espacial dos sistemas de irrigação do tipo pivô central e linear móvel licenciados e em operação no Rio Grande do Sul, de tal forma que estas informações possam ser aplicadas na otimização da gestão de recursos hídricos. O conjunto de dados utilizado no estudo foi fornecido pela Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler (FEPAM) e consistiu-se de coordenadas geográficas associadas aos sistemas de irrigação licenciados. Os sistemas de irrigação do tipo pivô central e linear móvel foram distribuídos nas doze principais bacias hidrográficas do Rio Grande do Sul. Verificou-se que há 1.285 equipamentos do tipo pivô central e linear móvel licenciados pela FEPAM, que irrigam uma área total de 91.849 ha. A maior concentração destes sistemas de irrigação está na região noroeste do estado, especialmente nas bacias hidrográficas do Alto Jacuí e Ijuí. Na região Sul, do Rio Grande Sul, apenas alguns sistemas do tipo pivô central e linear móvel foram observados, podendo este fato ser parcialmente atribuído à predominância de irrigação por inundação na cultura do arroz. Palavras-chave: Gestão de recursos hídricos, bacia hidrográfica, irrigação.  Manke, E.

E.IDENTIFICATION OF IRRIGATED AREAS BY CENTER PIVOT AND MOVING LATERAL IN STATE OF RIO GRANDE DO SUL  2 ABSTRACT Water scarcity in some Brazilian regions makes water resources management greatly important. Among the activities that need water, irrigation is considered the most demanding in terms of volume of water, and Rio Grande do Sul is one of the states in Brazil with the largest agricultural production. The objective of this study was to identify and quantify the geographical distribution of licensed center pivot and linear moving irrigation systems operating in Rio Grande do Sul state such that information can be applied to optimize water resources management. The main dataset used in the study was provided by Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler (FEPAM) and consisted of geographical coordinates associated with the aforementioned licensed irrigation systems. These irrigation systems were distributed on the twelve main watersheds in Rio Grande do Sul state. There are 1,285 center pivot and linear moving equipments licensed by FEPAM, which irrigate an area of 91,849 ha. The greatest concentration of this irrigation system is in the Northwestern of Rio Grande do Sul state, especially in Alto Jacuí and Ijuí watersheds. On the other hand, only a few of such systems were observed in South region of Rio Grande do Sul state and this can be partially attributed to the predominance of flood irrigation for rice. Keywords: water resources management, watershed, irrigation.

Three vegetable irrigation systems, semi-closed subirrigation (seepage), fully enclosed subirrigation (seepage), and drip irrigation, were evaluated for use on sandy soils with naturally high water tables to determine comparative irrigation costs for tomato production. Investment, fixed (ownership), and variable (operating) costs were estimated for each irrigation system. The investment costs of the drip irrigation system were significantly greater than those for the semi-closed and fully enclosed irrigation systems. The variable costs, however, for the semi-closed system were considerably less than those for the fully enclosed and drip irrigation systems. The semi-closed irrigation system, therefore, was determined to be the least-cost tomato irrigation system under present fuel cost and nonlimiting water supply conditions.
