(60) Сооружения проектируемые а частично уже и построенные на реке Янгце отличаются в первую очередь большими размерами. Занимается также с устьевыми и приморскими сооружениями. В заключительной части доклада знакомит читателя с работой водохозяйственных научно-исследовательских институтов, лабораторий, гидрометрической службы и университетов, обеспечивающих воспитание инженерных кадров. (Резюме автора, перевод от инж. Г. Чегиди > HYDRAULIC DEVELOPMENT IN NEW-CHINA (Part II.) By I. RÁCZ (For figures and photos see pp. 340—368 of Hungarian text) UDC 626/627 (51) The second part of the paper is devoted to the description of river systems for the catchment areas of which coordinated, multiple-purpose development projects have been prepared. b) The system of the Yellow River, although the second only as far as dimensions are concerned, is, because of its character, the most significant and, at the same time, the most dangerous in China (Figs. 12 to 15). The multiple development project of the Yellow River system is described here mainly according to the outlines propounded by Teng Tse-hui, the vice-premier of the State Council of the People's Republic of China at the First National People's Congress. The catchment area of the Yellow River comprises 745000 sq. kilometres. The springs are in Tibet in the Kun-Lun Range at an altitude of 4368 m. In preparing the project the watercourse has been divided into three morphologically different reaches. Plans have as yet been prepared for the two lower reaches only. ~ For the sake of clearness the central reach has been subdivided into further four sections with division points at the Lung-yang gorge, the Tsin-tung gorge (described in Hungarian geographical literature by the explorer L. Lóczy, member of the socalled Széehenyi-expedition in 1877—1880), further Ho-kou-cheng, and You-menkou. The river enters the Chinese Plains at the lower boundary of the central section and flows thereon in an elevated bed over the talus built by itself. Levees have been built along this reach thousands of years ago. Numerous changes of the course always coupled with disastrous floods (table IV.), have been recorded by history and merited the by-name "The Sorrow of China" for the river. The average discharge at Shensien is 1375 eu. m/sec, while the flood discharge at the same section is 22 000 cu. m/sec and the lowest discharge on record is 145 cu. m/sec. The average sediment concentration is very high, 34 kilogrammes/cu. m, while the observed maximum is 580 kilogrammes/cu. m. To control the floods of world-wide reputation and to harness the waters of the Yellow-River, the canalization of the river by 46 barrages forms the backbone of the development project. 44 of the barrages are on the central, while 2 of them on the lower reach. 5 of the total are multiple purpose projects, whereas the aim of 6 is mainly irrigation, that of the rest mainly energy production. The most significant among individual objects is the Sanmen-reservoir at the lower end of the central reach with a storage capacity of 65 cu. kilometres. Construction work started at the beginning of 1957, and is scheduled for completion by the end of 1961. A power station of 1100 MW capacity is to be built at the same dam. A number of structures is to be built also on the tributaries. The reforestation and agricultural program providing erosion control for the loess area is of outstanding significance. The proposed plan consists of two parts, the first of which requires the work of several generations and is the inclusive project, the second is, within the former,
