Studying waters of the Volgo-Don canal for the purpose of irrigation

The data on the quality of water for irrigation and measures to improve the uniformity of distribution of artificial rain along the water pipeline of the sprinkler in order to increase the quality of irrigation are given. It has been established that the uniformity of irrigation is affected by the quality of water, in particular the presence of small particles and impurities in it, which clog the sprinklers, leading to the cessation of water supply to the irrigated area. Plants do not get enough moisture, resulting in lower yields. Studies on the uniformity of the distribution of the rain layer when irrigating with the Don-K sprinkler showed that after the installation of a water purification system in front of the water pipeline input, a more uniform distribution of rain was observed along the water-conducting belt of the farm. The content of undissolved impurities decreased by a factor of 10, and the irrigation rate increased by 15%.

A two-directional calculation model for the combination uniformity coefficient of an impact sprinkler

An impact sprinkler loaded on a remote control trailer can be used for motion to improve the efficiency of a single Hard Hose Traveler in small and medium-sized irregular fields. Herein, a model for calculating the combination uniformity coefficient (CU) was established in the square test area under two-directional motion. The accuracy of the irrigation uniformity model was verified using the test data of application depth ( hn). The results revealed that the nozzle diameter, speed of sprinkler motion ( v), and motion methods can significantly impact the average application depth ([Formula: see text]) and the CU value of sprinkler irrigation performance. The motion methods included uniform motion and a constant speed combination motion. The highest CU values were recorded when the primary and secondary nozzle diameters were 10.5 and 4.5 mm, respectively (overall value, about 81.7%). The CU value gradually decreased with the increasing v value of the sprinkler. The CU value was higher under the constant speed combination motion than the uniform motion. The [Formula: see text] value gradually decreased with increasing v value. The [Formula: see text] value was classified based on the water requirement of different crops. The optimal CU value corresponding to each grade of the [Formula: see text] value was obtained in different schemes of the combination of sprinkler speeds. This research guides the realization of variable spraying of a Hard Hose Traveler and the intelligent uniform motion of the sprinklers.

A Review of the Category, Mechanism, and Controlling Methods of Chemical Clogging in Drip Irrigation System

Drip irrigation is an important way to alleviate the global water shortage. However, the emitter-clogging issue of drip irrigation directly affects irrigation uniformity and operation efficiency, even disabling the whole system and reducing crop production. Currently, with the widespread use of saline water and large-scale utilization of fertigation, the issue with the chemical clogging of emitters has become more prominent. The poor uniformity of irrigation and fertilization distribution caused by emitter clogging results in salt damage and fertilizer loss due to the complex clogging mechanism. However, no extensive information on chemical clogging is available. Herein, we surveyed the latest research on chemical clogging caused by saline water irrigation and fertigation in drip irrigation systems and described the clogging mechanisms of the emitter by analyzing the key factors, clogging rules, and substances. We also present a framework of the control technologies for clogging based on physical, chemical, and biological methods. Finally, we present the current challenges of fertigation with saline water and technical trends of emitter clogging in the drip irrigation system. To conclude, the efficient integration of these three methods is critical to prevent and eliminate chemical clogging.

Comparisons of Spray Characteristics between Non-circular and Circular Nozzles with Rotating Sprinklers

HighlightsExperiments were conducted to investigate the hydraulic performance of the solid-set rotating sprinkler.The effects of nozzle shape and working pressure on the droplet characteristics and kinetic energy of the rotating sprinkler were analyzed.The circular nozzle has a large wetting radius and large droplet size.Use of a non-circular nozzle could result in higher irrigation uniformity and lower kinetic energy imparted to the soil surface by water droplets under low working pressures.Abstract. Reducing the working pressure of sprinklers can effectively reduce sprinkler irrigation energy requirements. However, the reduction in working pressure and variation of nozzle shape inevitably lead to changes in the hydraulic performance of the sprinkler. To evaluate the spray characteristics of selected non-circular (the shape of the nozzle opening was asymmetric) and circular nozzles at low pressure, experiments were conducted to investigate the effects of working pressure, nozzle shape, and nozzle diameter on flow rate, radius of throw, water application rate, droplet size, droplet velocity of the rotating sprinkler, and kinetic energy of the water droplets impacting on the soil surface. The coefficients of irrigation uniformity were calculated for the non-circular and circular nozzles under different rectangular sprinkler spacing and working pressures. The results show that the flow rates of the non-circular and circular nozzles were equal under the same working pressure and with the same nozzle size, while the throw radius of the circular nozzle was longer than that of the non-circular nozzle. The circular nozzle produced a larger droplet size than the non-circular nozzle did. Since the droplet size and kinetic energy per unit droplet volume increased along the radius of throw, and the peak water application rate of the circular nozzle was located near the perimeter of the radius of throw, the peak specific power impact on the soil surface by the water droplets of the circular nozzle was greaterspecifically, 1.26 to 1.97 times that of the non-circular nozzle. With the increase in working pressure, the peak values of specific power and water application rate decreased. The irrigation uniformity coefficients of the non-circular and circular nozzles were more than 85% within the recommended pressure range of the manufacturer when the sprinkler spacing was less than 11 m. It was easier to obtain higher irrigation uniformity and lower impact kinetic energy under low working pressure when using a non-circular nozzle.

A hybrid dynamical systems approach to smart irrigation

We present a novel model for a drip irrigation system, using a hybrid dynamical systems paradigm to take into account the intrinsic binary nature of the control input. We consider an irrigation pipe with a generic number of drippers, analyzing the effect that the transients in the pipe have on the irrigation uniformity, and propose an intuitive irrigation strategy based on the one currently used by farmers. The model is presented together with simulations, whose parameters are based on real farm data.

Evaluating Uniformity of Center Pivot Irrigation Systems in Western Oklahoma

Highlights63% of the 24 center pivots tested in western Oklahoma had acceptable uniformity.On average, 7% of pumped water was lost before reaching the soil surface.Irrigation nonuniformity can have major, yet variable effects on water fluxes.Abstract. Nonuniform application of water through center pivots can lead to under- or over-irrigation at parts of the field, which can lead to water stress and yield reductions or loss of limited water resources and leaching of applied chemicals, respectively. In this study, irrigation uniformity tests were performed to determine the application uniformity and conveyance efficiency of 24 center pivots in western Oklahoma. The average coefficient of uniformity and low quarter distribution uniformity of the tested systems were 78% and 69%, respectively. These values indicate an overall borderline acceptable application uniformity. The average water conveyance efficiency was 93%, indicating that 7% of pumped water was lost before reaching the soil surface. Measured ratios of collected water in each collector to the average collected water for corresponding center pivots were used to simulate the effects of observed nonuniformity on water fluxes for a 10-year period. Under-irrigation (e.g., caused by clogged nozzles) led to considerable reduction in crop transpiration at the simulation location in the Panhandle, while the decreasing effects were more notable for deep percolation for the location in west-central Oklahoma. Over-irrigation (e.g., caused by leaks or missing nozzles) resulted in substantially larger deep percolations at both locations. Keywords: Catch-can, Conveyance efficiency, Water fluxes.

Effect of compensation chamber structure on the hydraulic performance of pressure compensating drip emitters

Pressure compensating (PC) emitters are installed at the end of the drip irrigation system to compensate for pressure loss and deliver water evenly to each crop. The PC emitter with excellent hydraulic performance can improve the irrigation uniformity of drip irrigation system. In this paper, the effects of main structural parameters of compensation chamber on the hydraulic performance of PC emitters were investigated by response surface methodology, and multivariate regression models were built to obtain the best hydraulic performance. The results showed that the minimum compensating pressure of PC emitters increased with the increase of compensation chamber height, while it decreased with the increase of compensation chamber diameter. The flow fluctuation exponent of PC emitters was affected by all the four structural parameters, which were outflow groove depth, outflow groove width, compensation chamber height and compensation chamber diameter. The outflow groove depth had the greatest influence on flow fluctuation exponent, and with the increase of outflow groove depth, the flow fluctuation exponent first decreased and then increased. Moreover, the value of the outflow groove depth influenced the effect of the other three parameters on flow fluctuation exponent. The optimal combination of parameters was: outflow groove depth of 0.14 mm, outflow groove width of 0.37 mm, compensation chamber height of 0.83 mm and compensation chamber diameter of 6.91 mm. The corresponding optimal results were: minimum compensating pressure of 38.73 kPa and flow fluctuation exponent of 0.024. The research provides a reference for the design and optimisation of PC emitters. • Interactions between parameters studied by response surface methodology. • Optimization goal was to reduce minimum compensating pressure and flow fluctuation of PC emitters. • Compensation chamber height and diameter had the opposite effect on performance index. • Overflow groove depth was the most important parameter affecting the flow fluctuation of PC emitters.

PHOTOVOLTAIC PUMPING: ALTERNATIVE FOR MICROIRRIGATION IN THE MATA MINEIRA AREA

The objective of the research was to evaluate the uniformity of drip irrigation with photovoltaic pumping with and without storage in batteries. using normal and self-compensating emitters. The experiment was conducted at the Federal University of Viçosa. Minas Gerais. Brazil. Two drip irrigation systems were tested. one with self-compensating emitters and the other with normal emitters with a flow rate of 4 L h-1. The coefficients of uniformity of Cristiansen and distribution (CUC and CUD) were used to evaluate the performance of the irrigation systems. The volumes pumped by the autonomous system and stored in batteries throughout the year in all regions of the country were compared for the period from 02/01/2018 to 01/31/2019. a period that contemplates the data collection phase of the experiment. According to the results. the uniformity of the drip systems with and without energy storage. with emitters normal and self-compensating presented a coefficient between 93% and 97%. classified as excellent. The largest volumes pumped throughout the year for drip irrigation systems with normal and self-compensating emitters without batteries occurred in the Northeast region of Brazil.

Translating open-source remote sensing data to crop water productivity improvement actions

A widely promoted approach to tackle food insecurity and water shortage challenges simultaneously is to enhance crop water productivity (WP). Therefore, multiple international organizations have featured WP improvements as their major policy goal, and substantial public and private investments have been made in this domain. Advances in remote sensing allow accurate, rapid, and cost-effective WP analysis for agricultural monitoring. However, translating the data to actionable information seems fraught with difficulties, as it only provides spatial and temporal variability in WP and no information on the causes of the variability. This paper introduces a standard approach using open-source remote sensing data for diagnosing reasons behind WP variations, comparing high performing fields (bright spots) with low performing fields (hotspots). The framework is applied to a case study on the Bekaa Valley in Lebanon considering wheat, potato and table grapes. Six factors (crop water stress, irrigation uniformity, soil salinity, nitrogen application, crop rotation and soil type) were analysed to identify their influence on WP and yield. This paper reveals that the growth of wheat and potatoes is negatively affected by water stress in the critical crop growth stages, non-uniform irrigation and nitrogen stress. Also, it was found that potatoes grown on clay-loam soil has better WP and yield than potatoes grown loam soil. Such information with regard to WP factors assists practitioners to identify priority areas and actions aiming at cropfield level WP improvement. While acknowledging errors, uncertainties and caveats inherent to the use of remote sensing data, this paper shows the feasibility and practical usefulness of the diagnostic framework.

Assessing water distribution characteristics of a variable-rate irrigation system

Variable-rate irrigation (VRI) can effectively improve the irrigation efficiency. In this study, we evaluated the two key indicators, irrigation uniformity and accuracy for a three-span center pivot VRI system with the combination of two sprinkler types, i.e., the Nelson D3000 (a fixed spray plate sprinkler, FSPS) and the R3000 (a rotating spray plate sprinkler, RSPS), two sets of irrigation depths designed for four management zones (zones 1–4) of 10, 8, 15, and 20 mm and 10, 15, 20, and 25 mm, and three cycle times (CTs) of the solenoid valve of 30, 45, and 60 s, with constant-rate irrigation (CRI) as a reference. In addition, the radially affected lengths of irrigation depths in zones 1–4 under various VRI treatments were further determined. The radial (mean CUH = 90.8%) and circumferential application uniformity (mean CUH = 95.6%) as well as radial irrigation accuracy (mean NRMSE = 15.3%) of the R3000 were superior to those of D3000 under VRI. The irrigation uniformity and accuracy of each management zone were less impacted by the designed irrigation depth and CT, but more affected by the location of the management zone. The irrigation uniformity and accuracy of VRI were close to those of CRI, indicating that the VRI system tested could guarantee the same application performance as the CRI system. Changing the D3000 sprinklers to R3000 sprinklers in the VRI system effectively reduced the radially affected lengths of management zones. The radially affected lengths of D3000 under various treatments were primarily distributed from 3–6 m, whereas those of R3000 were 0–3 m. Thus, it was recommended to select RSPSs in the design of the center pivot VRI system, and the transition zone and CT in relation to R3000 sprinklers were suggested to be 0–3 m and 60 s, respectively. This research provides the recommendations for better implementation of VRI.

Photovoltaic Direct Drive Water-saving irrigation System and Its Optimization Design Method

Photovoltaic irrigation has been widely used in many areas without conventional energy sources. In order to solve the problem of unstable operation and poor irrigation uniformity caused by the diurnal variation of solar radiation, a photovoltaic direct-drive water-saving irrigation system with automatic regulation was proposed. By using automatic control technology and the method of zonal rotation irrigation, all the electric energy generated by solar panels can be converted into irrigation energy under different light intensities, so that the water-saving irrigation equipment can work stably in different regions and the irrigation uniformity is ensured in different regions. According to the characteristics of solar energy resources and photovoltaic water-pumping units, the optimum design method of photovoltaic water-saving irrigation system is put forward. The minimum capacity of solar panels can meet the irrigation demand of a certain area, which can guide the engineering design of solar water-saving irrigation, greatly improve the engineering quality and energy utilization rate. It has the advantages of simple design, low cost, stable operation and energy-saving ring.

Analisisis Kinerja Sprinkler Mini Meganet 24 D Netafim Terhadap Variasi Debit dan Jarak Penempatan Sprinkler

Currently, there are many efficient and effective sprinkler irrigation tools on the market, so it is necessary to be careful in choosing for irrigation. Among them, the Meganet 24D Netafim, including the type of irrigation tool, which still needs testing to know its performance. This study aims to examine the sprinkler irrigation performance of Meganet 24D Netafim, on variations in flow rate and distance between sprinklers, related to irrigation uniformity (CU) and irrigation radius (Rn). This test was carried out on an area of about 1 acre, at a flow rate of Q1=0.42/sec, Q2=0.51 l/sec, Q3=0.52/sec, Q4=0.56 and the test sprinkler distance, r1=2 ,5m, r2=3m,r3 = 3.5m and r4 = 4m. The results of data analysis are presented in the form of tables and graphs and concluded descriptively. The results showed that, in all variations of Q and sprinkler spacing r1, r2, r3 obtained irrigation uniformity (CU) above 85% which was classified as high, while in the r4, Q1 and Q2 tests, CU was obtained below 85% which was considered low. All discharge variations, showing irrigation radius (R) about 5 m. So at r4 sprinkler spacing, it is not recommended in irrigation applications.

IRRIGATION UNIFORMITY OPTIMISATION OF A MINI-CENTRE PIVOT SYSTEM

In El Oued, southern Algeria, the traditional Mini-Centre Pivot System (MCPS) is widely used for the irrigation of agricultural crops, and its use has been growing continuously. However, these systems have a constant nozzle diameter along the lateral pipe, which affects productivity directly, besides decreasing both the quantity and quality of agricultural products by irrigation heterogeneity. Therefore, optimising the design of the MCPS nozzles is linked strongly to the desired uniform irrigation. This study aims to determine the optimal configuration of nozzles for high irrigation uniformity. To achieve this goal, a genetic algorithm was used for maximising the uniformity of MCPS-mediated irrigation. The optimisation is carried out according to water distribution modelling, calculation of the Heermann and Hein uniformity coefficient (CUH), and existing nozzle diameters. To verify the accuracy of the proposed model, three existing MCPS (60 m, 50 m, and 46 m in length) are investigated experimentally. The developed code findings in terms of CUH are in agreement with those obtained by experimental tests. The analysis indicated that the nozzle diameter should vary from 5 to 15 mm along the lateral pipe. In these optimal conditions, the CUH was improved by 29.77%, 33.99%, and 19.36%, respectively, for the existing 60, 50, and 46 m irrigation systems. The most obvious findings to emerge from this study is that using a genetic algorithm to optimise the design based on the nozzle size improves water application uniformity by more than 19% in terms of the CUH.

Two-dimensional spatial distribution modeling of sprinkler irrigation

Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use efficiency, which is intrinsically related to application uniformity. For the sprinkler method, the irrigation uniformity assessment is based on results of labor-intensive field tests in which the two-dimensional water distribution pattern is measured in a grid of catch cans. The aim of this study was to evaluate a simplified methodology for determining the irrigation uniformity using water depth distribution data of a single sprinkler head in operation, positioned at the intersection of two diagonal alignments containing regularly spaced catch cans. Three methods to simulate the spatial water distribution on the alignments were evaluated: linear interpolation (LI), cubic spline (SC) and second-degree polynomial regression (PR). Each of these methods were associated with a procedure to calculate the two-dimensional spatial water distribution. The adequacy of the LI and SC modeling methods was verified by using the Wilcoxon-Mann-Whitney test (p-value < 0.05) applied to the data of the field tests. Mean values of the coefficient of efficiency equals to 0.771 and 0.785 were obtained for the LI and SC methods, respectively. The PR method underperformed the others.

Evaluation of the Quality of Irrigation Machinery by Monitoring Changes in the Coefficients of Uniformity and Non-Uniformity of Irrigation

Recently, the development of agricultural technology has been focused on achieving higher reliability and quality of work. The aim of the presented paper was to examine the possibilities of evaluating the quality of work of wide-area irrigation machinery by monitoring the coefficients of uniformity and non-uniformity of irrigation. The object of the research was pivot irrigation machinery equipped with sprinklers with a total length from 230 to 540 m. The commonly applied quality of work parameter for wide-range irrigators is the irrigation uniformity coefficient according to Heermann and Hein CUH. Work quality evaluations were also carried out through other parameters applicable in practice, such as irrigation uniformity coefficients calculated according to Christiansen CU, Wilcox and Swailes Cws, and our introduced parameters, the coefficient ar (derived from the degree of unevenness according to Oehler) and the degree of uniformity γr (derived from the degree of non-uniformity according to Voight). Other applied parameters for determining the quality of work of wide-range irrigation machinery were the coefficients of irrigation uniformity according to Hart and Reynolds CUhr, further according to Criddle CUcr and subsequently according to Beale and Howell CUbr. Next, the parameters of the non-uniformity coefficient according to Oehler a, the coefficient of variation according to Stefanelli Cv, the degree of non-uniformity according to Voigt γ and the degree of non-uniformity according to Hofmeister Ef were evaluated. Field tests were performed during the growing season of cultivated crops (potatoes, corn and sugar beet) in the village of Trakovice (agricultural enterprise SLOV-MART, southwest of the Slovakia) and in the district of Piešťany (Agrobiop, joint stock company). During the research, the inlet operating parameters (speed stage, inlet pressure, irrigation dose), technical parameters (number of sprayers, total length, number of chassis) and weather conditions (wind speed and temperature) were recorded. The obtained results were examined by one-way ANOVA analysis depending on the observed coefficient or input conditions and subsequently verified by Tukey and Duncan tests as needed. Irrigation uniformity values ranged from 67.58% (Cws) to 95.88% (CUbh) depending on the input conditions. Irrigation non-uniformity values ranged from 8.58 (a, Ef) to 32.42% (Cv). The results indicate a statistically significant effect of the site of interest and thus the impact of particular field conditions (p &lt; 0.05). When evaluating the application of different coefficients of irrigation uniformity, the results showed a statistically significant effect only in the first test (p = 0.03, p &lt; 0.05). During further repeated measurements, the quality of work increased due to the performed inspection of all sprayers and the reduction in the influence of the wind.

Flow characteristics and diaphragm deformation of pressure‐compensating drip irrigation emitters*

AbstractPressure‐compensating (PC) emitters are extensively utilized because they can enhance the irrigation uniformity and the terrain adaptability of drip irrigation systems. To examine the interaction between the elastic diaphragm and fluid of PC emitters, the internal flow behaviour and the diaphragm deformation of PC emitters were studied by one‐way and two‐way fluid–structure interaction (FSI) numerical simulation methods. The deformation characteristics of the elastic diaphragm, the change of the outflow section around the outlet of the pressure‐compensating chamber, and the pressure and velocity distribution of the flow field were analysed in this study. The results illustrate that the deformation process of an elastic diaphragm during the entire working process could be divided into three phases: rapid deformation, slow deformation, and long‐term tiny deformation. After the diaphragm contacted convex land, the overflow groove was the only channel where water could flow out of the PC emitters; and as working pressure increased, the increment of the diaphragm deformation was extremely tiny. However, it was the tiny deformation of the elastic diaphragm that maintained the flow rate of the PC emitters constant over a wide range of working pressures. The results can provide references for exploring the pressure‐compensating mechanism of PC emitters and their optimal design.

Impact of the Intermittency Movement of Center Pivots on Irrigation Uniformity

A computer model was developed to simulate the varying depths of water applied to the ground due to the intermittent movements of a typical center pivot. The stop–go model inputs include the sprinkler application depth, the sprinkler pattern, that pattern’s wetted radius, the center pivot’s % timer setting, the move cycle time, and the end tower maximum travel speed. The model outputs were the depth of application in the pivot’s movement direction, the distribution uniformity (DU), and the coefficient of uniformity (CU). The results revealed that the pivot circular application uniformity is mostly a function of the move distance as a percent of the sprinklers’ wetted radius. This, in turn, is a function of the percent timer setting, the cycle time, and the end tower travel speed. Due to this, the high-speed center pivots had corresponding lower application uniformities compared to low-speed machines, and sprinklers with larger wetted radii resulted in better uniformity. Shortening the cycle time also resulted in higher uniformity coefficients. Based on these results, it is recommended that the run time be set based on the pivot end-tower’s travel speed and sprinkler wetted radius, such that the end tower move distance is equivalent to the sprinkler wetted radius. This will reduce wear to the tower motors due to the on–off cycling, especially for slow travel settings and for sprinklers with larger wetted radii. The ponding depths at different percent of the move distance, for the potential runoff, were estimated, which were set to be equivalent to the wetted radius.

Adaptive Prediction of Water Droplet Infiltration Effectiveness of Sprinkler Irrigation Using Regularized Sparse Autoencoder–Adaptive Network-Based Fuzzy Inference System (RSAE–ANFIS)

As the high productive efficiency of sprinkler irrigation is largely based on balanced soil moisture distribution, it is essential to study the exact effectiveness of water droplet infiltration, which provides a theoretical basis for rationally scheduling the circulation efficiency of groundwater in agricultural irrigation performance. This research carried out adaptive prediction of the droplet infiltration effectiveness of sprinkler irrigation by using a novel approach of a regularized sparse autoencoder–adaptive network-based fuzzy inference system (RSAE–ANFIS), for the purpose of quantifying actual water droplet infiltration and effectiveness results of precision irrigation in various environmental conditions. The intelligent prediction experiment we implemented could be phased as: the demonstration of governing equations of droplet infiltration for sprinkler irrigation modeling; the measurement and computation of probability densities in water droplet infiltration; innovative establishment and working analysis of RSAE–ANFIS; and the adaptive prediction of infiltration effectiveness indexes, such as average soil moisture depth increment (θ, mm), irrigation infiltration efficiency (ea, %), irrigation turn duration efficiency (et, mm/min), and the uniformity coefficient of soil moisture infiltration (Cu, %), which were implemented to provide a comprehensive illustration for the effective scheduling of sprinkler irrigation. Result comparisons indicated that when jetting pressure (Pw) was 255.2 kPa, the impinge angle (Wa) was 42.5°, the water flow rate (Fa) was 0.67 kg/min, and continuous irrigation time (Tc) was 32.4 min (error tolerance = ±5%, the same as follows), thereby an optimum and stable effectiveness quality of sprinkler irrigation could be achieved, whereas average soil moisture depth increment (θ) was 57.6 mm, irrigation infiltration efficiency (ea) was 62.5%, irrigation turn duration efficiency (et) was 34.5 mm/min, and the uniformity coefficient of soil moisture infiltration (Cu) was 53.6%, accordingly. It could be concluded that the proposed approach of the regularized sparse autoencoder–adaptive network-based fuzzy inference system has outstanding predictive capability and possesses much better working superiority for infiltration effectiveness in accuracy and efficiency; meanwhile, a high agreement between the adaptive predicted and actual measured values of infiltration effectiveness could be obtained. This novel intelligent prediction system has been promoted constructively to improve the quality uniformity of sprinkler irrigation and, consequently, to facilitate the productive management of sprinkler irrigated agriculture.
