The Mokelumne River basin of central California comprises portions of the California Trough and the Sierra Nevada section of the Pacific Mountain system. The California Trough is divisible into four subsections-the Delta tidal plain, the Victor alluvial plain, tlie river flood plains and channels, and the Arroyo Seco dissected pediment....

In May and June floods occurred in the Canadian and Pecos River Basins of New Mexico that were unusually high and in many places were record breaking. The floods were caused by heavy rains that occurred over the eastern part of the State from May 23 to June 4 in...

It is quite generally known that ocean‐tides produce fluctuations of the water‐level in wells of the artesian type located close to the seashore by periodically changing the external load on the aquifer [see 1 of “References” at end of paper]. Fluctuations of ground‐water as a result of earth‐tides, however, are...

The Geological Survey has been engaged for more than 50 years in measuring and publishing the discharge of streams of the United States. Measured discharges have ranged in quantity from a small fraction of a second‐foot measured volumetrically to more than 2,000,000 second‐feet measured by use of the current‐meter equipment...

In January and February 1937 the Ohio and mid-Mississippi Rivers experienced floods which, over reaches many hundreds of miles in length, exceeded all previously recorded stages. When measured by the loss of life and property, extent of damage, and general disruption of human activities, these floods constituted a major catastrophe. The...

During the period March 9-22, 1936, there occurred in close succession over the northeastern United States, from the James and upper Ohio River Basins in Virginia and Pennsylvania to the river basins of Maine, two extraordinarily heavy storms, in which the precipitation was almost entirely in the form of rain....

Ogden Valley is a fault trough bounded on both the east and west by faults that dip toward the middle of the valley. This fault trough contains unconsolidated deposits of clay, sand, and gravel, whose thickness is more than 600 feet. These materials are stream and lake deposits and in...

Memphis is located in the part of the Gulf Coastal Plain known as the Mississippi embayment. It is underlain by unconsolidated sand and clay formations of Tertiary and Cretaceous age. The Wilcox group, of Tertiary age, and the Ripley formation, of Cretaceous age, are excellent aquifers, and all the water...

The Kansas legislature in 1917 passed the Water Commission act, entitled, "An act relating to floods, drainage, water power, domestic water supply, navigation, irrigation, and providing for state control of all matters relating thereto, and providing for a Water Commission in the state of Kansas." Under this act the Water Commission...

Late in February and early in March, 1902, there occured upon the drainage basin of the Passaic River in northeastern New Jersey the most disastrous flood in the history of the region. Not only was the discharge the largest recorded, but the flood was the most destructive to life and...

The profiles here represented are derived from various sources and differ from one another greatly in accuracy. Many of them are drawn from the annual reports of the Chief of Engineers, U.S.A., under which are included the reports of the Mississippi and Missouri River commissions. The heights thus obtained are...
