Water Resource Management in Distributed Irrigation Systems

The important waterways of the Amu Darya and the Syr Darya run in Central Asia, which have their own tributaries and provide fresh water to the regions of several countries. One of the problems of farming is water supply. Here, an important role is played by special climatic and tectonic conditions, different spa- tiotemporal levels, the filling capacity, and dependence of water bodies on rainfall, snow melting, the presence of erosion-accumulative processes, and the formation of a micro-stream network. Since water management systems and facilities have large spatial dimensions, as well as many technological parameters, it is possible to obtain quantitative and qualitative changes in their characteristics only on the basis of mathematical mod- eling methods. To date, there is no unified systematic approach to the issue of modeling the dynamics of water management facilities, there is only a wide class of mathematical models of individual objects of different complexity. That is why the choice of mathematical models that will describe the complex processes of water distribution in water management systems with the required degree of accu- racy is a very problematic task.
