Excerpt from Remarks on the Improvement of Tidal Rivers
The influx of the tidal wave through Firths or Bays, and the modification it receives in its passage up the inclined beds of rivers, produce two physical boundaries, which are found to exist in all rivers, when viewed in connection with the sea. These boundaries, again, produce three sec tions or compartments, to the improvement of only one of which the practical remarks I have now to offer refer, but it is necessary that they should be clearly defined, before proceeding to what has been sketched out as the special subject of observation. The seaward, or lowest of these sections, I have elsewhere termed the sea proper the next, or intermediate one, into which the sea ascends, and from which it again withdraws itself, I termed the tidal compartment of the river and the highest, or that which is above the influence of the sea, the river proper. Their relative extent, in different situations, is influenced, not only by the circumstances under which the great tidal wave of the ocean enters the river, but by the size of its stream, the configuration and the slope of its bed, and.

Paperback. Condition: New. Print on Demand. This book delves into the topic of inland navigation, examining the various theories and practical opinions that have been proposed over the centuries, from the time of early philosophers to the present day. Despite the wealth of information available, the author laments the lack of well-established principles to guide navigation improvements, leading to a reliance on costly trial and error approaches. The book argues that a shift in focus away from the regulation of freshwater streams and towards increasing the duration of tidal influence is crucial for effective navigation improvements. It emphasizes the importance of understanding the tidal phenomena and physical characteristics of a river to identify and remove obstructions that hinder the propagation of the tidal wave and impede the flow of currents. Through case studies and examples, the author demonstrates the effectiveness of works such as deepening the riverbed, constructing guiding walls, and removing obstacles in enhancing tidal influence and improving navigation. By providing a comprehensive examination of the historical and theoretical underpinnings of inland navigation and offering practical insights into effective improvement strategies, this book serves as an invaluable resource for engineers, practitioners, and anyone interested in the history and development of inland waterways.
