A dissertation on rivers and tides : Intended to demonstrate in general the effect of bridges, cuttings, removing of shoals and imbankments; and to investigate in particular the consequences of such works on the River Thames. By Robert Erskine, engineer, &c. Respectfully addressed and recommended to the consideration of the nobility, gentry, and public at large; particularly the proprietors of lands on the banks of the Thames, between Cricklade and Gravesend, with a view to the amendment of the ruinous condition of the navigation, the putting a stop to the intended lockwork between staines and London, and the usurpation of city power, in imbanking and raising paths on the side of the river, where they never were before.
