The objective of this contribution is to provide information on a generally applicable optimisation procedure intended for designing a system of terraces and retention reservoirs within integrated territory protection from the harmful effects of soil erosion. The formulated procedure is a universal tool which can be used for any territory. An optimisation mathematical model was used to find the most suitable combination of various elaborated pre-optimisation variants of the soil conservation and flood prevention measures under the given conditions of each particular habitat. This model was created on the basis of a mixed discrete programming. The model compilation and its analysis on a high performance computer was performed using the model and calculation system GAMS. The model solution was controlled by one or more simultaneously operating optimisation criteria. A system of terraces as an important part of the soil erosion and flood control was chosen to verify the possibilities of the described optimisation procedure utilisation. The system was proposed within the land consolidation in the case study areas of Hustopeče and Starovice cadastral areas. First, the model function and performance were verified. Then the possibilities of experimentation on the model of the solved system of complex conservation measures were tested. The main results of the real and some experimental solutions are summarised. The results of practical applications of the integrated territory protection model validate its functionality and universal applicability.Keywords:
