the UK. Many aspects of design and construction are discussed including background to the project, hydrolog[z, topography and geology, dam studies - the alternatives open and discussion of fill, foundations and the concrete toe wall and grouting-, instrumentation, diversion works and construction. 1116 WAKLSTROM, EE The safety of dams and reservoirs. WATER POWER,V27, N4,APR .1975, P142-144. A concise appraisal of the increasingly important problem of dam and reservoir safety is presented, and causes of failure, safety inspections, monitoring difficulties and instrumentation are examined. 1117 MARWICK,R GH~MOND, JP The river Lar multipurpose project in Iran. Part 1.17F, IT. W A T ~ POWER, V27,N4,APR .1975,P133-141. This project was designed to meet the rapid rise in demand for water by the city of Tehran, but will also provide water for irrigation and peak hydro power generation. In this paper the 105m high embankment dam, and the 20kin long t~mnel and power station system to divert water to Tehran, are discussed. The geolog~ and topography of the Ler gorge and valley are also discussed. 1118 FIVES,MO Design and construction of the upper reservoir at TurloughHill. 5F. WATER POWER,V27,N3,MAR.1975,P89-95. Conm~issioned last year, the Turlough Hill pumpedstorage station in the Republic of Ireland features a 2.3 cubic kmartificialupper reservoir with an asphaltic concrete lining. Design ~qd construction of the reservoir, based on the success of asphaltic concrete linings in Europe, are described in detail in this paper, together with an account of the first few months of reservoir operation. 1119 VARSHNEY,RS Pre-design estimates for arch dams - Pert I. WATER POWER,V27,N2,FEB.1975,60P. Many factors influence the siting of an arch dam at a particular site, and it becomes very difficult for the designer to select a preliminary section and layout and to assess the construction quantities involved. Data from over 100 arch dams were examined by the author, from which the various formulae and charts presented in this article were developed to provide guidelines for preliminary evaluation.
Dams other than embankment dams
1122 SARKARIA, GS KOLLGAARD, EB SHARMA, RP New stress studies of old arch dams - Part I. WAT~q POWER, V27,N5,MAY 1975,P173. The authors describe the application of three independent techniques of stress analysis to three existing concrete arch dams in the western USA. These structures are between 55 and 27 years old and so represent different design concepts and construction practices. The foundation cenditions and concrete quality also vary greatly for each case. The da~s are the Pacoima, Ross and Lake Spalding, the two latter being discussed in part I of this paper. 1123 VARSHNEY,RS Pre-design estimates for arch dams _ Part II. 6F,3T,7R. WATER POW~, V27, N3, MAR .1975,P99-I03. Current guidelines for prel~m~ary design estimates for archdams were discussed in part I of this paper. The author concludes with part II containing graphs for determining concrete quantities for different dam types, and reco~endations for new dam layouts based on analysis of data from existing structures. i124 CARATI sL Calculation of the stresses on the cc~sole and arches of the Frera dam by mesns of electro-acoustlc strain gauges placed within cubes of concrete trisxially calibrated previously. In French. 12F,2T. SEMINAR ON CONCRETE STRUC%~JRES SUBJECTED TO TRIAXIAL STRESSES. ISMES, MAY 1974,N68,NOV.1974,16P. The author describes the positioning of instruments into the body of the Frera dam and illustrates in detail the positioning of the electro-acoustic strain gauges put there for the purpose of recording the stress that is produced on five arches and the main console by filling and emptying of the reservoir. The strain gauges had been placed in cubes of concrete and trlaxially calibrated before installation.

A brief description of the rock weathering process is given and a review of the recently published literature on the design of foundations in weathered rock is presented, together with conm~nts on the procedures currentlyin use. Stress distribution and its effects on the settlement of structures in weathered rock are examined and a suitable design method suggested.
