Calculation of irrigation regime is based on soil water balance estimation in specific soil and climatic conditions. On the project phase the calculations of water balance are made for the 'year types' using the fixed data of water balance. A model of soil water regime, allowing calculating project irrigation parameters, is made. For irrigation parameters determination the graphical model is made. A principal scheme of soil water content dynamics on the module area and industrial land during straight and reverse irrigation is presented. Mathematical formulas of irrigation cycle are calculated. An algorithm of model analysis of reclamation design order is elaborated for coordination of reclamation components of pilot and working areas. This algorithm implements a condition of dynamic similarity and balancing of water schedule of soils. Components of the reclamation design order of a working area – pre – water storage and reclamation rate – are set by application of this model to the established reclamation order of a pilot area.
