the top-soil flows to the canals through gravel-filled intercepting wells. The water level of the seepage canal is regulated to constant level by automatically controlled pumping stations.

The gated floodway operates to support the water transfer in time of floods. The structure having twelve openings with 12 m width each, is closed by flat gates. The flat gate contains a web plate with two girders. The gates are handled by the 15 Mp gantry crane travelling over the weir. The same flat gates are used for the upstream bed closing. Over the structure a two-way service bridge spans with a runway level at El. 94,60 m A. O. D.

The most important elements of water distribution are the Nagykunság and Jászság Irrigation Main Canals.

The canal is designed for conveying a discharge of 89 cu. m/sec, by gravitation a part of which is distributed over 126 000 hectares in its own irrigation system, the other part is transferred to the Körös Valley.

The length of branch No. 1 of the main canal is 57,65 km and reaches the Hortobágy—Berettyó River at Mezőtúr. At its cross-section at 39,49 km, the Nagykunság Main Canal No. 2 branches off. Main Canal No. 2 is 35,25 km long and reaches the Hármas-Körös River between the weirs at Békésszentandrás and
