Calculation of the main hydrological parameters of regime for irrigation areas.

Innovative models of appropriate operational methods for liquids are considered in the present paper. The risks posed by the climate change in agriculture have significant impact on irrigation. In choosing the irrigation areas with the aim to increase crop yields, a number of interconnected factors must be taken into account. Wide range of physical and chemical processes occurring in soil fundamentally affects its fertility and potential, filtration and capillary capacity and the dynamics of changing moisture content. The problem is equally actual both for arid and swampy soils. Particularly noteworthy is the influence of mineralization of soil and its hard soluble substances on the speed of chemical and biological processes of plant growth and development. The speed is directly related to the resistance of constituent minerals and hard soluble substances of soil. Certain influence on soil fertility is exerted by plant uptake of food from soil, rates of microorganism development and chemical and biological processes. Water consumption for irrigation is related to water supply parameters and soil characteristics on irrigation areas. In the model of plant growth-development particular attention is paid to the irrigation regime. The irrigation regime is directly related to soil and ground parameters. Due to the complexity of the issue, the factors related to the irrigation process in the zone of complete soil saturation and aeration are thoroughly taken into account. Based on the generalized model of the new relations of hydrology and hydraulics, the distribution of irrigation water on the irrigation areas without losses is considered. In order to mitigate irrigation erosion processes, new calculation relations are derived.
