253. lappuse - It may be cheapest to carry the canal around these obstructions, or it may be better at once to cross them by aqueducts, flumes, or inverted siphons, or to cut or tunnel through the ridges. Careful study should be made of each case, and estimates made of the cost not only of first construction, but of ultimate maintenance. In crossing swamps or sandy bottom lands it may be cheaper, because of the losses which the water will sustain from absorption, to carry the canal in an artificial channel through...

254. lappuse - In finally locating an expensive work, borings and trial pits should be made — the former by means of a light steel rod, and the latter by simple excavation — in order to discover the nature of the material to be encountered. In making the final survey of a canal, it is well to place at convenient intervals permanent benchmarks of stone or other suitable material. The establishment of these along the side of the canal in some safe place, will give convenient datum points to which levels may be...

300. lappuse - From the observations thus made, the rating is determined either by formula or by graphic solution. The distance through which the meter is drawn, divided by the time, gives the rate of motion or velocity of the meter through the water. The number of revolutions of the wheel, divided by the time, gives the rate of motion of the wheel. The ratio of these two is the coefficient by which the registrations are transferred into velocity of the current.

The ground flow need not necessarily reach the same stream as the surface flow, but the dip of the strata may carry it into another valley. The ground flow frequently emerges as springs; but the larger portion of it generally reaches the stream through the banks, and in some cases through the bottom of the channel. A study of the material and dip of the strata,...
