What reading level is Report On the Improvement of the Kanawha And Incidentally of the Ohio River, By Means of Artificial Lakes book?
To quickly assess the difficulty of the text, read a short excerpt:
The accuracy of these measurements has never since been tested, until the present year, when I gauged the river again — the first time below Lykin's Shoal, and the second at Buffalo.
The discharge computed from the surface velocities^ without reduction^ was — Below Lykin^s Shoal . . 1237 cubic feet per second.
At Buffalo .... 1^49 " Between the times of taking these two observations, the river had risen about 5 inches at Buffalo, above what had been the extreme low water of this year.
None of t...he observations which I herein report are to be regarded as mere computations from the speed of a surface float in the centre of the channel, with a reduc- tion made in accordance with De Prony's rule. In taking them, the river was divided, in one case, into four, and in the other into six spaces, by buoys, of which the position was determined by angles from a base line on shore, and the surface velocities obtained at each buoy by duplicate observations.
The ground selected at Buffalo was remarkably favora- ble for the purpose.
