Geology and ground-water resources of Plum Island, Suffolk County, New York
H. C. Crandell
1962, Water Supply Paper 1539-X
Plum Island, which has a total area of about 1.3 square miles, is about 2 miles off the northeast tip of Long Island. It is underlain by Cretaceous and Pleistocene unconsolidated deposits resting on a southeastward-sloping Precambrian bedrock surface. The island's fresh ground-water reservoir is contained in stratified upper Pleistocene...
A formula for computing transmissibility causing maximum possible drawdown due to pumping
G.M. Robinson, Herbert E. Skibitzke
1962, Water Supply Paper 1536-F
By modifying the Theis nonequilibrium formula a relation is found in which the maximum possible drawdown is expressed in terms of a unique value for the aquifer coefficient of transmissibility. The relation is valid for any specified period and rate of pumping, for a given aquifer coefficient of storage, and...
Ground-Water Reconnaissance at Pinnacles National Monument, California
R. E. Evenson
1962, Water Supply Paper 1475-K
Ground-water supplies at Pinnacles National Monument have been obtained from springs that occur in fractures and along bedding planes of volcanic flows and deposits, and from springs discharged from perched water in a sedimentary fanglomerate formation. The spring-water yield is barely adequate to supply existing camp facilities, and therefore a...
Theory of aquifer tests
J.G. Ferris, D.B. Knowles, R. H. Brown, R.H. Stallman
1962, Water Supply Paper 1536-E
The development of water supplies from wells was placed on a rational basis with Darcy's development of the law governing the movement of fluids through sands and with Dupuit's application of that law to the problem of radial flow toward a pumped well. As field experience increased, confidence in the...
Geology and ground-water resources of the Ahtanum Valley, Yakima County, Washington
B. L. Foxworthy
1962, Water Supply Paper 1598
The Ahtanum Valley covers an area of about 100 square miles in an important agricultural district in central Yakima County, Wash. Because the area is semiarid, virtually all crops require irrigation. Surface-water supplies are inadequate in most of the area, and ground water is being used increasingly for irrigation. The...
Reconnaissance of ground-water resources in the Eastern Coal Field Region, Kentucky
William E. Price, D. S. Mull, Chabot Kilburn
1962, Water Supply Paper 1607
In the Eastern Coal Field region of Kentucky, water is obtained from consolidated sedimentary rocks ranging in age from Devonian to Pennsylvanian and from unconsolidated sediments of Quaternary age. About 95 percent of the area is underlain by shale, sandstone, and coal of Pennsylvanian age. Principal factors governing the availability...
Geology and ground-water resources of Fond du Lac County, Wisconsin
Thomas G. Newport
1962, Water Supply Paper 1604
The principal water-bearing rocks underlying Fond du Lac County, Wis., are sandstones of Cambrian and Ordovician age and dolomite of Silurian age. Other aquifers include dolomite of Ordovician age and sand. and gravel of Quaternary age. Crystalline rocks of Precambrian age, which underlie all the water-bearing formations, form a practically...
Effect of reservoir storage on peak flow
William D. Mitchell
1962, Water Supply Paper 1580-C
For observation of small-basin flood peaks, numerous crest-stage gages now are operated at culverts in roadway embankments. To the extent that they obstruct the natural flood plains of the streams, these embankments serve to create detention reservoirs, and thus to reduce the magnitude of observed peak flows. Hence, it is...
