The main purpose of drainage, as one of the traditional amelioration measures, was to adjust the water and air regime of agricultural soils, i.e. to optimise the moisture and aeration of soils in terms of plant needs, soil workability and its carrying capacity for agricultural machinery. Due to changes in the economic conditions, progressive erosion of the land, unprofessional or rather neglected maintenance, ageing of structural elements, etc., quantitative and qualitative changes in the water regime of entire river basins have been occurring for a long time. The possible existence of drainage structures enters into the design of virtually all types of water management measures on small watercourses and in agricultural catchment areas and should be taken into account and used appropriately in these measures. Drainage water can subsidise small reservoirs, pools and wetlands, but only if the applicable standards are met, the technical design is appropriate, and the required water quality is maintained. The selection of the area for the implementation of small water bodies must be carefully considered with regard to the hydrological, morphological and soil conditions of the environment, the limits and possibilities of the area, especially with regard to the downstream processes in the area (management of the surrounding land, connection to the hydrographic network, etc.). In the present study, a procedure for the design and construction of small water bodies on drained land is presented using the outputs of a multi-criteria analysis based on the search for an optimal solution through the selected factors.
