This geologic map has been prepared from the photographic data returned by Ranger VII and is one of a series prepared from the data returned by the Ranger VII, VIII, and IX spacecraft. The map area, in Mare Cognitum, includes the Ranger VII impact point. The map shows the...

This report presents basic criteria, in the form of tables and graphs, for each of the four methods of hydrologic design most commonly used in the San Francisco Bay region--flood-frequency analysis, Rational Method, unit-hydrograph method, and runoff simulation by means of hydrologic basin modeling. The term "hydrologic design" as used...

This report shows the effects that the construction of half a mile of one-lane roadway during June, July, and August 1970 and construction of a 5-acre pond during August and September 1970, had on sediment concentrations and sediment discharge of a stream draining an area of 0.76 square mile. The...

This report was prepared as a part of a study of the ground-water resources of Cache Valley, Utah and Idaho. The study by the U.S. Geo- logical Survey was made during 1967-70 in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The U.S. Bureau of Reclamation...

Ground-water withdrawals for irrigation increased from about 84,000 acre-feet to 430,000 acre-feet per year between 1960 and 1970 in the northern High Plains of Colorado, causing significant water-level declines in areas where high-capacity wells are concentrated. The number of wells increased from about 500 in 1960 to 2,560 in 1970....

The U.S. Soil Conservation Service is actively engaged in the installation of flood and soil erosion reducing measures in Texas under the authority of ''The Flood Control Act of 1936 and 1944" and ''Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found...

The magnitude and frequency of floods is defined regionally for streams in New Mexico. An analysis was made, using multiple- regression techniques, relating flood peaks of 2, 5, 10, 25, and 50-year recurrence intervals to selected physical and climatic basin characteristics. The state was divided into three flood regions, and...

A method is presented for estimating flood-frequency information for urban areas in Missouri. Flood-frequency relations are presented which provide an estimate of the flood-peak discharge for floods with recurrence intervals from 2.33 to 100 years for basins with various degrees of existing or projected urban development. Drainage area sizes for...

During the summer and fall, seepage and evaporation losses from Horseshoe Lake, an oxbow or an 'old river' lake adjacent to the Mississippi River, exceed inflow to the lake, and seasonal declines of 2.5-3.0 feet in the lake level are common. In exceptionally dry years, the minimum lake level has...
