I shall assume from the start that it is a manager's duty and desire to make the enterprise for which he is responsible ever more efficient and effective. There are many reasons why he should do so - such as the United Kingdom's desperate need for higher productivity, the need to make a profit, the fact that the whole enterprise may otherwise go bankrupt (not a bad reason in itself), and that no manager worth his salt can achieve any personal satisfaction if the job for which he is responsible is not running well and effectively - but these reasons are side issues to us now.
The advent of nuclear energy has given rise to many matters with which the civil engineer is intimately concerned. Some of these are discussed, based on a review of the available literature: the design of structures to resist complicated blast forces caused by atomic weapons, the design and construction of concrete biological shields, the disposal of radio-active wastes, the problems associated with the structural design and erection of nuclear reactors, and the use of radio-isotopes, e.g. in the detection of leaks in pipelines, the study of the flow of water in rivers and the determination of the density and moisture content of soils and concrete. The need for research is indicated. The view is expressed that because of developments in the use of nuclear energy, the civil engineer should become thoroughly versed in the basic sciences of physics and chemistry and that he will have to work in close co-operation with experts in these fields.
The Author has introduced such a diversity of interesting topics, not only in the fields of hydrology and hydraulics but also of structures and soil mechanics in this most valuable paper that one finds difficulty in selecting a reasonably small number of points to discuss.
