Special Issue Information

Dear Colleagues,

The main topic of this Special Issue is the “Design, Management and Environmental Control of Modernized Irrigation Systems”. Taking into account that water is becoming increasingly scarce and valuable resource, the modernization of irrigation systems must not only seek water savings, but also to maintain the greatest possible amount of good quality water in the reservoirs. By increasing water use efficiency, we not only increase the amount of water available for other uses, but also improve the environmental quality of irrigated areas, decreasing fertilizer and phytosanitary products losses and contamination of groundwater. This increase in efficiency goes hand in hand with an improvement in the design of irrigation systems and an improvement in water management, linked to greater automation and support for control elements. Besides, with the incorporation of environmental criteria in the design and management of the modernized irrigation systems, the agricultural sector can contribute to the maintenance of a healthy and sustainable agroecosystem, and consequently a better life quality in rural areas and stabilizing population.

In this Special Issue, all themes that concern modernized irrigation systems are welcome, from the first step of modernization (design), to the study of the influence of the different factors involved in irrigation water management (including the contribution of the control elements in the water use and distribution). Environmental factors and repercussion of the irrigated lands in the agroecological system are also welcome to this Special Issue.

The changes in hydrological conditions observed nowadays require economical use of water. This applies to water management both on a national scale and river basins and catchments, as well as on the scale of drainage systems and individual drainage networks. Outflow regulation is carried out by extending the outflow time of surface water collected during rainfall in various forms of retention in the catchment area. One of the devices for regulating the outflow of groundwater is a drainage network, traditionally used as a drainage system. The water level regulators presented in this article enable the damming of water in the drainage network, in pipelines and in the adjacent ground. The conducted tests were aimed at determining the hydraulic characteristics and operating conditions of two innovative solutions of water level regulators in drainage systems. These regulators are characterised by the possibility of smooth regulation by the use of rotary or propeller systems for smoothly setting the damming level. Both tested regulators are characterised by the presence of an effective flow, the value of which was set at the level of Qe = 0.17 l·s−1 to Qe = 0.25 l·s−1 for the funnel regulator and Qe = 0.009 l·s−1 to Qe = 0.015 l·s−1 for a hole regulator. Laboratory tests of the prototypes showed that the funnel regulator allows one to maintain the damming level in a flow rate range of up to 5.5 l·s−1, with possible damming up to 3 cm, regardless of the height of the shaft. The hole regulator is characterised by a flow control range of up to Q = 0.65 l·s−1, greater variability of the damming levels and the need to change the position of the working openings, depending on the flow rate.

Injectors are key pieces of equipment for chemigation systems, and their hydraulic performance has a significant effect on chemigation systems and crops. In order to investigate the influence of different working parameters on hydraulic performance for a water-powered proportional injector (PI), three key parameters of inlet and injection flow rate were researched using a one-factor experimental design method. The regression equations between different factors and response variables were established through a response surface method based on one-factor experimental results. Lastly, a mathematical model of the actual injection ratio was established. Some experiments under different, randomly selected parameter combinations were carried out to verify the prediction precision of the mathematical mode. The results showed that the injection flow rate increased first within the differential pressure of 0.05 to 0.10 MPa and then tended towards stability with increasing differential pressure. The injection flow rate decreased by increasing the viscosity and the change in the injection flow rate was small enough when the viscosity was greater than 500 mPa·s. The impact factors, in order of significance, for inlet flow rate were differential pressure, viscosity of injection liquid and setting injection ratio. The impact factors, in order of significance, for injection flow rate were viscosity of injection liquid, setting injection ratio and differential pressure. The regressive model for predicting the actual injection ratio was validated using an experiment and the relative deviation between calculated value and tested value was less than 5.98%, which indicated that the mathematical model had high credibility.
