Experience has shown that by increasing the grip width it would be possible to reduce the intensity of rain while maintaining labor productivity, which is achieved by studies using the proposed newly developed spouts installed on the ISAD sprin-kler, which provides a relatively low rain intensity, which is explained by the desire to create a microclimate for plants with low water consumption with limited geometry of the irrigated areaThe experimental work that we carried out here at the accepted research facilities in Terter, Zagatala and Ganja on the irrigation of soya, sugar beet, corn and tobacco allows us to give an approximate average rain intensity (mm/min) at an irrigation rate of 300-500 m3/ha, depending on the soil: Sandy -0.3 0.4, light loamy -0.2, 0.3

If we look at the existing irrigation methods used today in the country, then they are divided into: ground, rainfall, underground or underground, drip and spray. Basically, they are transferred to the irrigation field in two forms: through gravity and pressure irrigation systems. Naturally, a gravity irrigation system is economically more expensive than a low pressure irrigation system. However, from a performance appraisal stand point, pressure irrigation methods are less efficient and have serious disadvantages

Sustainable Irrigation

In Afghanistan, water is mostly used for agricultural purposes. The water supply chain requires updating to ensure its sustainability. Different irrigation methods – such as surface water based irrigation (via canals), groundwater based irrigation, and the Karez irrigation system – are applied across the country. Considering the compatibility of the Karez system with the environment, it can be deemed the most effective irrigation scheme, as it allows collecting a significant amount of groundwater and conveying it to land surface via sub-horizontal tunnels using gravity. This article analyzes Afghanistan’s Karez irrigation systems currently feeding water to over 170,000 ha of farmland with a potential to expand and become a component of sustainable water supply chain.

Purpose: development of a computer algorithm for a quantitative assessment of the hydraulic parameters of an irrigation and drainage system with the possibility of integrating different irrigation methods. Materials and methods. The design of structures for combined irrigation is based on hydraulic calculation. A feature of such systems is the ability to change irrigation methods, which is associated with a significant change in hydraulic parameters and the complication of hydraulic design of structures. Automation of hydraulic calculations based on a universal computer algorithm is the most acceptable way to solve the problem and the basis for designing combined irrigation systems. Results. A feature of the proposed algorithm for determining the quantitative parameters of the combined irrigation system is the use of a step-by-step approach followed by the formation of a generalized hydraulic screenshot of the entire structure. A screenshot of hydraulic parameters here means a quantitative assessment of hydraulic indicators for all nodal points of a structure, implemented by a calculation method for given, stationary modes of system operation. A set of this kind of static screenshots allows you to evaluate the process in dynamics, as well as to carry out comparative assessments of hydraulic parameters under different operating modes of the combined irrigation system. The algorithm offers an original way to identify objects based on the use of a linear coordinate system. The method makes it possible to organize an enumeration of the structural elements of the system and a step-by-step calculation of hydraulic parameters from the inlet section of the design segment to any given nodal point. Conclusions. The calculation results according to the proposed algorithm make it possible to form a specially organized data array, which is a set of symbolic-numeric values that determine the pressure level and water flow rate and identify them with the nodal point of the system.

AbstractThis paper, based on historical research on irrigation administration in the Dongping area and on-site investigations into its current state, explores the benefits and problems produced by two institutional changes. As a common pool resource situation, irrigation systems’ “provision” and “appropriation” are two separate issues; any institutional change must thus offer two different solutions. The study concludes that the participatory changes undertaken in the Dongping irrigation area failed, in the end, to resolve the problem of irrigation system sustainability. In particular, it proved difficult for collective action to take place around provision, which led to difficulties in operating the irrigation system.
