(62) DEVELOPMENT OF HYDRAULIC CONSTRUCTION IN HUNGARY By H. Lampl, Cand. of Eng. Sc. and Prof. E. Mosonyi, Memb. of the Hung. Acad, of Sc. (Figures and photos on pp 373—404 of the Hungarian text.) 626/627 : 624 (439.1) The article demonstrates the latest development of hydraulic construction on works of the Tiszalök Dam commissioned off this year. Hydraulic construction received greater impetus at the beginning of this century. In 1904—1906 was built on the River Kőrös the dam (needle dam of Poirée system) and ship lock at Bökény as early examples of hydraulic construction in reinforced concrete. (Fig. 10). The first model test was executed in 1908 (Photo 8), and the Cement and Concrete Testing Laboratory of the Hydraulic Service was established in context with the construction of the ship lock and feed sluice of the Soroksár Danube Arm (1908-1914, Photo 1-2). After World War I. construction of Budapest Free Port was the first major hydraulic construction (1924 — 28, Photo 3). In the same period was executed the first important groundwater lowering job at the foundation work of the shiplock at Tass, the outlet of the Soroksár Danube Arm. Concrete was poured from a tower (1927-30, Photo 4). In 1931 —32 was built on the River Rába the Dam at Nick with a modern stilling basin instead of the former conventional long apron (Photo 12). The Békésszentandrás Dam built on the Kőrös River under the Irrigation Act 1937: XX represents the next stage of development (Fig. 1—3, photos 5 — 7). The Tiszalök Dam built after World War II. has thus far been the biggest hydraulic construction job in Hungary (Fig. 4 — 9, photo 13 — 20). The dam with three gates of 37 m width each assures the diversion of 60 m

3/sec water for the irrigation of 125 000 hectares on the left bank of the Tisza river. A shiplock of 85 x 17 m and a 11 520 kW power plant are parts of the dam scheme. 4 million cu.m. of earth moved and 90 000 cu.m. of concrete and reinforced concrete placed visualize the size of the dam scheme. The paper describes the location and design as well as the execution of the project. Formerly hydraulic constructionworks were designedas individual jobs, at present plans for all hydraulic purposes are drafted with consideration of all branches of the nation's economy. This has been made possible by the General Plan of National Water Economy laid out in 1954 and by establishing the National Water Board with authority in all matters of water. Construction is preceeded by planning upon sound scientific and economic basis in which model tests play an important part (Photo 8—10). The first Hydraulic Laboratory was established in Hungary by Prof. S. Rohringer of the Technical University of Budapest. Present higher claims are met by the very much extended laboratories of Technical University and by the new big laboratory of the Besearch Institute for Water Besources. L'ÉVOLUTION DANS L'EXÉCUTION DES TRAVAUX HYDRAULIQUES EN HONGRIE Par II. Lampl, candidat des sciences techniques et E. Mosonyi, membre correspondant de l'Académie (Figures et photos voir pp. 373 à 404 du texte hongrois.) 626/627 : 624 (439.1) Les auteurs illustrent l'évolution accomplie dans l'exécution des travaux hydrauliques par l'aménagement de la Tisza a Tiszalök. La réalisation de travaux hydrauliques a pris un nouvel essor au début de ce siècle. C'est alors que fut construit (1904 — 1906) sur la rivière Kőrös à Bökény un barrage (à aiguilles, système Poirée) et une écluse, exemples précoces de l'application du béton armé dans les constructions hydrauliques. (Fig. 10.) C'est à cette époque que furent exécutés les premiers essais sur modèles réduits (1908, photo 8), et que fut créé à l'occasion de la construction de l'écluse du bras de Soroksár du Danube (photos 1—2) le laboratoire d'essai pour ciments (1908 — 1914).
