Seite 69 - ... Hot Springs. The zero of the gauge-rod here is opposite the east edge of the fifth upright of the first span from the east and on the upper side of the bridge. The outer rim of the pulley-wheel is 3 feet from the zero of the gauge-rod, and from the end of the weight to the pointer on the wire rope is 26.03 feet. On September 3 Mr. Babb measured the French Broad at Hot Springs, NC, 38 miles below Asheville, the water at that time being 22.80 feet below the top of the sixth iron support in the...
Seite 159 - ... each irrigation. The method of irrigation is wholly that of flooding. When water is needed the sluice boxes are opened and the water is allowed to flow over the land until the irrigator is satisfied The practice is usually to flood the land to a depth of from 3 to 4 inches over the entire surface. All the ditches carry a surplus of water, and as a consequence the, use of water is excessive. The surplus water from the irrigated fields and the ditches is allowed to find its own way to the river,...

Seite 58 - Railroad bridge. The distance from the zero of the rod to the outside of the pulley wheel is 3 feet; the length of the wire rope is 33.17 feet. The water power from Dan River has been developed to a considerable extent at Clarksville.
Seite 66 - At Hinton, on New River, 2 miles below its junction with the Greenbrier, the Weather Bureau has a gage. On this heights are read up to 10 feet by means of a rod fastened to a pier in the river, this' being about 50 feet from shore at the time of low water The heights above 10 feet are read on a rod fastened to a tree on shore. The pier in the stream consists of a wooden crib about 25 feet square and 10 feet high, filled with rock. There are no bridges across New River in this vicinity. This point...
Seite 59 - ... the rod being over the center of the second vertical compression member of the second truss from the south end of the bridge. The distance from the zero of the rod to the outside edge of the pulley wheel is 1.3 feet, and from the end of the weight to the pointer on the wire is 52.90 feet.
Seite 17 - If there are a half dozen or more of these points well distributed according to height of water, it will usually be found that they will lie approximately in the path of a parabolic curve. This curve can be sketched through or near the points, the hydrographer, from his intimate knowledge, giving greater weight to some points than others, and this curve will then show the relation of gauge height to discharge for the period under consideration.
Seite 59 - SC, and about 60 miles below the Catawba Station, now abandoned. A wire gage of the ordinary type is fastened to the upstream guard rail on the upper side, the 2-foot mark on the rod being over the center of the second vertical compression member of the second truss from the south end of the bridge.
