The visual-tube method for sedimentation analysis of sands was developed as a part of the general investigation titled "A Study of Methods Used in Measurement and Analysis of Sediment Loads in Streams." The method is one answer to the need for a simple, rapid, and inexpensive means of determining the sedimentation-size frequency analysis of sand samples containing particles less than one millimete

The structural geology and the distribution of aquifers in the southeastern part of San Juan County were studied to establish the relationships of fresh-water aquifers to the oil- and gas-bearing rocks in that area.

Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots. Although not confined to the arid regions of the Western United States, their occurrence there is more common, more spectacular, and, because of their effect on water supply, more important than it is in humid and subhumid regions. Most phreatophytes have low economic value, and con

Natural waters in North Dakota have been arbitrarily defined in this report as saline or fresh; water containing more than 1,000 ppm (parts per million) of dissolved solids or having a specific conductance greater than 1,400 micromhos per centimeter at 25°C is considered to be saline. A large proportion of the available water supply of North Dakota is saline.

The Hueco Bolson is in the extreme western part of Texas and south- central New Mexico, covering parts of El Paso County, Tex., and Dona Ana and Otero Counties, N. Mex. Wells tapping the bolson deposits furnish the major part of the water supply for the city of El Paso, Ciudad Juarez, Fort Bliss, Biggs Air Force Base, and private industries. in the area. The progressively increasing demand for wat

The investigation in the Bonanza Lake area of northwestern Power and southeastern Blaine Counties was made to determine the direction of ground-water movement and to ascertain the relation of the regional ground-water body to the Snake River. The surface of the area is nearly flat to gently rolling, and slopes to the west. Lake Channel, an abandoned channel of the Snake River, and a few volcanic c

An accelerated use of water resulting from a growing population, industrial expansion, and irrigation has brought into focus the importance of the quality as well as the quantity of this natural resource in Utah. As new demands are made on the existing supply, a search goes on for new sources of ground and surface water. These new sources must not only meet quantity requirements, but also must fal
