The Tliird Five-Year Plan of Water Resources Developmcnt By Dégen, I. Head, National Water Authority Before the General Assembly of the Hungárián Hydrological Sooiety reviewing activities of the year 1965, the author (Head of the National Water Authority) presented a survey of water management projects completod during the seeond Five-Year Plan period frorn 1961 to 1965 and informed partieipants about the trends of development during the third FiveYear Plan from 1966 to 1970. During the second Five-Year Plan period completed, water management in Hungary achieved considerable development. Signifieant progress was made in the exploration and survey of both surfaee and subsurfaee water resourees. Növel methods were elaborated for compiling and representing the national water balanee. Relying on the survey of resourees and demands as well as on the possibilities of development a long-range Water Management Perspeetive Plan has beent prepared. Irrigation was extended by about 200 000 hectares. Munieipal water supply was made available to almost 1 millión inhabitants. Pollution of watereourses could be maintained at the previous level by effective legislative measures, development of wastes treatment teehnology and the eonstruction of new sewage treatment plants. Within the framework of national economy planning, centralized poliey was realized in water management activities on various branches. The new Water Aet was presented to, and passed by, the National Assembly. During this FiveYear period several high flood waves travelled down our rivers, thus in 1963 on the Tisza River and the reeord high water on the Danube in 1965, but disasters could be diverted successfully. Investments for water management projects totalled at 12.1 thousand millión Forints during the seeond Five-Year Plan. Of this totál 19% have been devoted to river training, flood control, watershed protection and reclamation purposes, 26% to agricultural development, 12% to industrial supply and round 41% to domestic supply and sewerage of settlements. In the third Five-Year Plan 14.0 thousand millión Forints are envisaged for water resourees development projects, amounting to 5.4% of totál simultaneous national investment. As a reault further 1.1 millión inhabitants will be served by water works, raising the proportion to 55%, and the totál water production capacity to 2.1 millión cu.m per day. Besides the four régiónál water works under construction at present, eonstruction of two additional ones will be commenced. By the construction of a number of new industrial water works the volume diverted from the population for industrial purposes will be reduced appreciablv. Effective steps will be undertaken towards the exploration and development of the especially rieh thermal water resourees of the country. The expansion of irrigation areas will be reduced to a rate attaining only onefourth of the previous one, but several prineipal works will be constructed. Most important of these is the second Barrage on the Tisza River at Kisköre, which will entail fundamental changes in water management along the central reach of the Tisza River. An artificial laké covering one-fifth of the area of Laké Balaton will be created and 150 cu.m/sec will be delivered for the irrigation of 300 thousand hectares, navigation conditions will be improved, supply to numerous communities and industries will become possible. Rafety against highwaters will be increased, especially along the Danube River. For this purpose additional 10 millión cu.metres of earth will be placed to strengthen existing flood levees. Increasing utilization of water resourees calls for the refinement of exploration, surveying and perspeetive planning methods, as well as for the more accurate determination of water use standards and directives. Together with the development of hydraulie construction agencies, mechanization of earth moving will be raised from 87 to 92%, the share of precast elements in concrete structures will be increased to 40%, productivity of transportation and handling in river training rubble work will be improved by the addition of new, up-to-date equipment, etc. In conclusion the measures taken in compliance with the introduction of the new poliey of economy management in Hungary have been outlined.
