NOTES
Soviet Ground-Water Laboratory The U.S.S.R. has 369 hydrological posts involved in research for I.H.D. One of them, near Moscow, has a laboratory built below the water table. Here scientists directly observe the behaviour of the water table. An automatic instrument records the exact level of the ground water, the quantity of moisture used in irrigation, and the amount of evaporation. The humidity of the soil is determined by a neutron counter.
Water Resources Management in OECD Countries The re-use of waste water in a highly industrialised and densely populated environment is the subject of a report just published by the Organisation for Economic Co-operation and Development as part of its studies on water resource management. Growing demand and dwindling good-quality resources is a problem common to most Member countries, and in this context the report examines the case of Germany where water treatment and recycling methods are used on a wide scale for maintaining the necessary quantity and the adequate quality of supplies to the public, industry and agriculture. The study forecasts that the re-use of wate water will become more essential as pressure on available resources of good quality increases in the future. On average, some 10 per cent of all waste water from cities, towns and industries in Germany is used again for domestic and industrial purposes. Industry itself recycles more than 60 per cent of its needs.
International Seminar for Hydrology Professors, Utah, USA, 1970 The above Seminar was originally planned to be held in Logan, Utah, USA, from 12 to 24 July, 1970. The Organizer of the Seminar has announced that, in order to avoid overlapping with other events, the Seminar will now be held from 2 to 14 August, 1970. The programme of the Seminar, as already announced, remains unchanged.
International Field Year for the Great Lakes The International Field Year for the Great Lakes has been scheduled to take place during the calendar year 1972. 213

NOTES
The I F Y G L is a comprehensive programme of synoptic scientific studies of Lake Ontario, its drainage basin, and the weather over them. It is a joint United States-Canadian undertaking, in which data will be collected by scientists from both countries and then shared through Data Centres established at Detroit, Michigan, and Burlington, Ontario. The Field Year programme, actually seven years long, is part of the U.S. and Canadian National Programmes for the International Hydrological Decade. The knowledge gained will be of importance well beyond the Field Year. Lake Ontario, for example, may be considered as representative of all large lakes. Many of the natural processes to be observed there are found in other, similar, bodies of water, form neighbouring Lake Erie to Lake Baikal in Soviet Siberia. The design of recreational facilities, municipal sewage and water-supply systems, and navigational works is dependent on the kinds of information to be sought by the scientists participating in the Field Year. Such work is also important in providing data needed for effective restoration and maintenance of acceptable water quality in the Great Lakes. Additional information is available through the office of the U.S. National Committee for I H D or from John E. Hanna, Public Affairs Officer, Dept. of the Army, Lake Survey District, Corps of Engineers, 630 Federal Bldg. Detroit, Michigan 48226.
Symposia International Symposium of Ground-Water; Evaluation and Utilization of Ground-Water Resources. December 6-18, 1970. Hotel Villa Igiea, Palermo. Information from: Dr. Aurelio Aureli, Segreteria del Convegno, E.S.A., Via Liberta, No. 201/bis, Palermo, Sicily. Subjects for discussion: (1) Evaluation of evapotranspiration losses. (2) Characteristics and structures of aquifers. (3) Hydrological balance of a basin for the evaluation of usable ground-water resources. (4) Conservation of ground-water resources. (5) Ground-waters in the economic management of the water resources of a basin.
