Abstract
Land reclamation is important in the development of agricultural production for unfavorable climatic conditions. This necessitates the improvement of scientific and methodological approaches to the creation and operation of water management and reclamation facilities, including drainage systems, which are adapted to these changes. Approaches to the type and design of drainage systems based on a combination of a modern progressive optimization approach with the traditional water balance method, hydrodynamic and hydraulic methods are presented. Approaches to the systemic optimization of technological and design solutions for the creation and operation of drainage systems have been determined. It seems that the drainage system is a complex natural and technical ecological and economic system. Finding the general optimum in such a system based on the system optimization consists in substantiating local optima for all its main components of heterogeneous elements in the system effect - mode - technology - design in their interconnection. The practical implementation of a complex of predictive-simulation and optimization calculations in projects for new construction, reconstruction and modernization of drainage systems based on the developed scientific, methodological, information and software can be carried out using the appropriate toolkit, which is CAD and modern BIM technologies. The transition to optimization methods will improve the feasibility and overall technical, technological, environmental and economic efficiency of the creation and operation of water management and reclamation facilities in accordance with modern requirements.

In modern conditions, a significant amount of agricultural products in order to improve food security is grown on lands with a regulated water regime using various types and designs of reclamation systems (RS)
The aggravation of the greatest challenges of our time concerning the energy, food and water crises under the influence of changes in climatic and anthropogenic factors both at the planetary and regional levels necessitates further improvement of scientific and methodological approaches to the creation and operation of water management and reclamation facilities that are adapted to these changes, including for drainage systems (DS) in the drainage reclamation zone based on an assessment of their overall efficiency in compliance with modern economic and environmental requirements [1]
In the development of these approaches, we [3] presented that such a system as part of an agricultural production system (APS) and hydro-reclamation systems (HRS) should be considered as a complex natural and technical, ecological and economic system (CNTEES)
Summary
A significant amount of agricultural products in order to improve food security is grown on lands with a regulated water regime using various types and designs of reclamation systems (RS). It turned out that in the modern conditions of the transition to market relations in the country, this method, as a simplified optimization method, in the form in which it was implemented, considered only the economic component of optimization and does not take into account environmental efficiency when determining the optimal technical and technological solutions and their parameters, that does not correspond to modern requirements [4]
