South of Budapest an irrigation and drainage canal system extends from the left bank of the main river into the Kskunság area. The canals differ in size, discharge and salinity. Management includes mowing of aquatic vegetation and dredging. Macrophyte surveys were carried out in part of the main canal (Dunavölgyi-föcsatornat), in the medium-sized Harmincas-Canal, and in the smaller Apaji-Canal. The main canal receives its water directly from the Danube River. Water flow is slow, there is no shading by riparian vegetation and the water is rich in nutrients, but usually clear. Water temperatures are relatively high in summer and are beneficial for species like Ceratophyllum demersum, C. submersum, Trapa natans, Cabomba caroliniana and Najas marina. For the first time a floristic-ecological characterization was possible for part of the canal system. The occurrence of the neophyte C. caroliniana, and the high species richness found in the canals make them interesting and valuable habitats for the aquatic vegetation, despite their anthropogenic origin.
