The utility model provides a novel high speed waterway network for flat areas. The novel high speed waterway network is simple in integral structure and relatively easy to realize, is higher in development and application values, and includes two main channels connected to the river, a connecting channel connecting the two main channels, three channels arranged on one main channel and three trench channels arranged among the three channels, wherein barrages are arranged on the two main channels respectively; barrages are arranged at the two ends of the connecting channel respectively; barrages are arranged on the outer parts of two branched channels, so that water levels of the upstream and downstream main channels keep stable. The expansion area of the water transport network for flat areas and ports, wharfs and work zone water area thereof is large, the construction land of the expansion area is obtained through the plenty of replacement land saved through intensive use in integration of urban and rural areas in the flat areas; and besides, the water transport network has good regulation and storage capacity, thereby greatly improving the flood control standard, the water log control standard, the probability of irrigation of the engineering areas.
