Árvízvédelem, folyó- és tószabályozás, víziutak Magyarországon (OVH, Budapest, 1978)
D) Víziutak - Idegen nyelvű összefoglaló
The rate of development was accelerated in the wake of the floods in 1954 and 1956 on the Danube and in 1947 on the floods in 1954and 1956 on the Danube and in 1947 on the Tisza river. The way and rate of development were determined in the National Master Plan of Water Management approved in 1965. The regulations actually valid have been formulated in the Cabinet-decision No. 2006/1973 on the principles for the perspective development of water management. Observing the philosophy included in the development objectives, in 1974 basic principles were elaborated by the National Water Authority for the new design criteria of flood control structures. Accordingly, the design flood is understood as the flood level and flood load (i.e. duration above a given level) for which any flood control structure should be dimensioned. Starting from these basic principles new design flood levels were specified in 1976 which are included in detail in a National Water Authority publication entitled ’’Design floods of the rivers in Hungary”. The development of flood control systems is discussed in separate chapter. It describes in detail the economic, environmental, etc aspects as well as the impacts of human activities and advances in technology to be considered in the course of future developments. Further, it provides a description of the advanced methods used in the design, construction and maintenance of control structures, and the research and development tasks involved in the improvement of these activities. The section dealing with the guidance and organization of flood control outlines the functions of official supervision and management, and the cooperation agreements with the individual countries — i.e. coordination of the development objectives, observation of the common flood control regulations and improvement thereof, exchange of data in forecasting, etc — can have significant influence on the flood safety in Hungary. The level of flood safety in the country is greatly influenced by the technological standard and efficiency of the organization which is responsible for the function of flood fighting in a national flood control system developed to provide a limited degree of safety only. This task can be accomplished by a well organized, technically well equipped and well trained organization covering the whole territory of the country and vested with the authority to draw, if necessary, on the country’s resources for flood fighting services. The national flood fighting organization established to meet these requirements is capable of performing the tasks, its training is good and its equipment is suitable. Its efficiency was positively demonstrated by fighting successfully the large floods in the last decade. This efficiency must be maintained in the future and both its organization and equipment must be maintained on an up-to-date level, since the improvement of the national flood control system to the specified safety will take still a long time during which the economic values protected will increase rapidly, so that any flood disaster would cause increased losses. The first part of the chapter River training describes in detail the morphologic and hydrologic characteristics of our rivers. In the course of preliminary work to river regulation engineering data must be explored and collected on all physiographic, geomorphologic, hydrologic and hydrau718
