'(16) The system would be completed by three pumped storage projects on the Upper Dráva River. The Yougoslav hydroelectric system would have a peak output of 1,500 MW, together with the common Dráva —Mura stations this output could be raised to 1,900 MW. 3. Hernddy, A. Eng. : The Kaloesa Irrigation system (For the Hungarian text see pp. 116) The largest sprinkling irrigation system of the country has recently been completed between the Danube and Tisza Rivers. Two pumping stations, each of 800 lit/sec capacity (by Pellizzari) are operated automatically, control being provided by the network pressure, respectively water consumption. Pressure may rise to 10 atmospheres. Physical opportunities of the area are very favourable. The layout is shown in Fig 1. An area of 4,000 hectares can be irrigated, which is divided into blocks of "200 hectares, respectively into plots of 50 hectares. The main pipeline of asbestos cement pipe is 21 km long and has a diameter from 400 to 500 mm, while the diameter of the secondary network is 200 mm. Illés, Gg., Eng. : The Vl-th Conference of the International Water Supply Association, Stockholm (For the Hungarian text see pp. 121) The conference was held from the 15th to 19th June, 1964, and contributions were invited on five main subjects: 1. Protection of Catchments against pollution; 2. Pollution of water and soil by oil compounds; 3. Pollution control; 4. Ozonetreatment of water ; 5. Materials promoting settling. The Conference was followed by a technical exhibition. The Conference published a separate paper on the dangers of pollution. Mr. B. M. Nilsson was elected president. At the Conference Hungary was represented by 7 engineers. BOOK REVIEW 1. Kézdi, A. and Marko, I: Protection and unwatering of earth structures (Földművek védelme és víztelenítése) Vol. 2. Reviewed by P. Salamin The first volume which was devoted to exploration for earth structures, stability of slopes, foundation of embankments, earth pressure and lining walls, as well as surface drainage, appeared in 1962. (A review can be found in Hydraulic Review, No. 4, Vol. 1962). The second volume was published in 1964 on 261 pages, with 397 figures and 45 tables and its main subjects are unwatering of construction pits (open pits, groundwater lowering etc.) Drainage of earth structures, highways, railways, airports and land melioration, as well as the biological protection of earth structures and banks are dealt with on an engineering level. Practical suggestions are given for planning, constructing and maintaining earth structures subject to water pressure. Detrimental movements and deformations of earth structures are discussed and protective measures against such movements and deformations are dealt with in detail.
