Tides of rivers?Variations in the tidal lines?Professor Robison-s remarks on the anomalies of river tides?Nature of the inquiry into river tides?Tide-gauges ?Selection of stations for tide observations?Agents which produce disturbance in the parallelism of the tidal lines?Manner in which these variations affect the soundings?Datum line for soundings?Use of tide-gauges in reducing soundings to the datum?Formula for their reduction?Formula only true on the supposition of the lines being parallel to high water?Results affected by erroneous supposition ? Most effectual means of avoiding inaccuracy; but this not always practicable?General rules for taking soundings?High and low water soundings?Formulse for ascertaining th'e rise of tide and height of sandbanks?Cross sections?Mr. Henry Mitchell-s rule for determining elevations along a tidal river without levelling; not applicable to rivers in this country. Tidal The hydrometric observations to be first noticed are observations. . those of the tides, and it is essential that they be scrupulously correct, as they determine the accuracy of all soundings of the depth of water, and of all sections of the bed of the river, which are generally constructed from the data afforded by the sounding-line. The information afforded by the tidal and other hydrometric observations is also indispensable, as will afterwards be seen, in enabling the engineer to form an opinion on many important questions that are being constantly brought before him, and I therefore offer no apology for discussing this part of the subject at some length. The tides of rivers are influenced partly by the circumstances under which the great tidal waves of the oceanenter their mouths or estuaries, and partly by the size ...<

One of the leading figures in the age of great engineers, David Stevenson (1815-86) was the son of a lighthouse builder, and while studying at Edinburgh University he was already gaining experience at his father's side. It is for his lighthouses and works of inland navigation that he is best remembered: he designed Britain's most northerly lighthouse and worked on improving navigation on rivers such as the Dee, the Forth and the Clyde. His article on inland navigation for the One of the leading figures in the age of great engineers, David Stevenson (1815-86) was the son of a lighthouse builder, and while studying at Edinburgh University he was already gaining experience at his father's side. It is for his lighthouses and works of inland navigation that he is best remembered: he designed Britain's most northerly lighthouse and worked on improving navigation on rivers such as the Dee, the Forth and the Clyde. His article on inland navigation for the Encyclopaedia Britannica was published separately in 1858, and was revised and updated for this second edition in 1872. Although Stevenson acknowledges that the age of the canal has been superseded by the age of the railway, he maintains that there is much to learn from the older technology. Illustrated with cross-sections and plans, this work will be of interest to readers seeking to explore the history of Britain's industrial infrastructure.
