The different techniques used in the design and operation of drainage- subirrigation systems in low-lying riverine areas in Poland are presented. The required groundwater levels used as designing criteria and the applications of the steady state and unsteady state approach to ditch (drain) spacing design in different soil conditions are discussed. The practical application of groundwater level maintenance using the techniques of controlled drainage, subirrigation with a constant water level, and subirrigation with a regulated water level, are shown for three different field sites.
