PREFACE.

IN the following chapters no attempt has been made to describe the details of, or make calculations for, any particular scheme, because, as stated in the opening chapter, the conditions vary so considerably in every case that what is applicable to one place is totally unsuitable for another. The matter contained therein has, therefore, been confined, as far as possible, to the fundamental principles involved, and these have been dealt with in such a manner that the information may be utilised to suit the exigencies of all cases; as, for instance, where formulæ are required, such as for calculating the discharge of weirs and of pipes, several alternative ones are mentioned, and their solution explained, so that, by selecting the most suitable, accurate results can be obtained. In dealing with the behaviour of concrete employed in submarine works, the results of the most important experiments of recent years are given at length, and with regard to the actual design of sea outfalls, numerous typical examples are given, one of which, or an adaptation thereof, may be selected for application in any given case. The surveying problems that may be required in connection with the current observations are all given with the necessary calculations, and are expressed in such a manner that they can be utilised by any one with a knowledge of logarithms and the use of logarithmic tables, even if they have no knowledge of trigonometry.
