Leopold, Luna B. Vegetation of southwestern watersheds in the nineteenth century. 1951.

Scope and Content Note

Abstract: To determine the general conditions of vegetation in pre-grazing days in the Southwest and what changes, if any, have occurred in the last 50 years, the author has inspected and analyzed the original journals of early explorers and travelers and compared early photographs (1895-1903) with more recent ones taken from the same spot. Originally published: The geographical review ; v. 41, no. 2 (1951).
Folder 1.6

Leopold, Luna B. Rainfall frequency : an aspect of climatic variation. 1951.

Scope and Content Note

Abstract: Analyses which have been made in the past have shown no significant trend in annual values of rainfall during the period of rainfall records in the southwestern United States. In the present study, frequency of daily rains of various sizes are analyzed for four long-record stations in New Mexico. Frequency of rains of various sizes comprising wet years and dry are compared. Some effects of changes in rainfall frequency on vegetation and erosion are discussed. Originally published: Transactions of the American Geophysical Union ; v. 32, no. 3 (June 1951).
Folder 1.7

Leopold, Luna B. Downstream change of velocity in rivers. 1953.

Scope and Content Note

Abstract: Because river slope generally decreases in a downstream direction, it is generally supposed that velocity of flow also decreases downstream. Analysis of some of the large number of velocity measurements made at stream-gaging stations demonstrates that mean velocity generally tends to increase downstream. Although there are many reaches in nearly all rivers where mean velocity decreases downstream, the general tendency for conservation or for downstream increase was found in all data studied. Originally published: American journal of science ; v. 251 (August 1953).
Folder 1.8

Leopold, Luna B., and M. Gordon Wolman. River meanders. 1960.

Scope and Content Note

Abstract: Most river curves have nearly the same value of the ration of curvature radius to channel width, in the range of 2 to 3. Meanders formed by meltwater on the surface of glaciers, and by the main current of the Gulf Stream, have a relation of meander length to channel width similar to rivers. Because such meanders carry no sediment, the shapes of the curves in rivers are evidently determined primarily by the dynamics of flow rather than by relation to debris load. Originally published: Bulletin of the Geological Society of America ; v. 71 (June 1960).

Folder 1.10

Leopold, Luna B. Rivers. 1962.

Scope and Content Note

Abstract: Rivers are both the means and the routes by which the products of continental weathering are carried to the oceans of the world. Except in the most arid areas, more water falls as precipitation than is lost by evaporation and transpiration from the land surface to the atmosphere. Thus there is an excess of water, which must flow to the ocean. Rivers, then are the routes by which this excess water flows to the ultimate base level. Originally published: American scientist ; v. 50, no. 4 (December 1962).

Leopold, Luna B., and Walter B. Langbein. River meanders. 1966.

Scope and Content Note

Abstract: The striking geometric regularity of a winding river is no accident. Meanders appear to be the form in which a river does the least work in turning; hence they are the most probable form a river will take. Originally published: Scientific American ; v. 214, no. 6 (June 1966), p. 60-70.

Leopold, Luna B. Trees and streams : the efficiency of branching patterns. 1970.

Scope and Content Note

Abstract: Extending the analysis of branching patterns of the drainage net of rivers, originated by Horton, the relation of average numbers and lengths of tree branches to size of branch was investigated. It was found that, as in river drainage nets, there is a definite logarithmic relation between branch order and lengths and numbers. Originally published: Journal of theoretical biology ; v. 31, pt. 2 (1971).
Folder 1.18

Leopold, Luna B. River channel change with time : an example. 1973.

Scope and Content Note

Abstract: Monumented channel cross sections were resurveyed over a period of 20 years (1953 to 1972) to determine the amount and kind of change of channel area and position on a 3.7-square mile basin, Watts Branch near Rockville, Maryland. Despite a trend toward increasing cross-sectional area, the net result after 20 years was a channel smaller by 20 percent than it had been originally. Urbanization did not alter the rate of channel migration. Originally published: Geological Society of America bulletin ; v. 84 (June 1973). Leopold's address as retiring president of the Geological Society of America, Minneapolis, Minn., November 1972.

Leopold, Luna B., and William W. Emmett. Bedload measurements, East Fork River, Wyoming. 1976.

Scope and Content Note

Abstract: A bedload trap in the riverbed provided direct quantitative measurement of debris-transport rate in the East Fork River, Wyoming, a basin of 466 km( drainage area. Traction load moves only during the spring snow melt season. Data collected in three spring runoff seasons showed that transport rate is correlated with power expenditure of the flowing water and at high flows becomes directly proportional to power as suggested by Bagnold. Originally published: Proceedings of the National Academy of Sciences ; v. 73, no. 4 (April 1976).
Folder 1.21

Folder 1.22

Leopold, Luna B., and William B. Bull. Base level, aggradation, and grade. 1979.

Scope and Content Note

Abstract: The influence of local base level and the effects of a change of base level can be separated from the influence of hydrologic and geomorphic processes with the basin under certain conditions: 1) observed changes in the longitudinal profile by aggradation or degradation when a local base level is lowered or raised while the basin remains unchanged; 2) observed changes in aggradation and/or degradation of a valley fill alluvium during periods of unchanging local base level. Originally published: Proceedings of the American Philosophical Society ; v. 123, no. 2 (April 1979).
Folder 1.23

Leopold, Luna B. Techniques and interpretation : the sediment studies of G.K. Gilbert. 1980.

Scope and Content Note

Abstract: The laboratory experiments on sediment transport conducted by G.K. Gilbert differed importantly in technique from such studies of more recent date. Gilbert's flume was level and could not be altered in slope. Sediment was introduced at the upper end at a predetermined rate and deposition built a bed gradient sufficient to transport the introduced load. The adjustment of slope in Gilbert's flume has contributed to the idea widely held by geologists that a river achieves equilibrium by adjusting its slope to provide just the velocity required for the transportation of the supplied load. Originally published: Geological Society of America ; special paper 183 (1980).
Folder 1.24

Leopold, Luna B. The Alexandrian equation. 1987.

Scope and Content Note

Folder 1.25

Leopold, Luna B. Ethos, equity and the water resource. 1990.

Scope and Content Note

Abstract: Discusses two concepts from ancient history and their relevance to the field of water in the modern age: 1) democratic governance at the will of the people was effective and responsive as long as there existed an ethos in administration, guiding beliefs even though unwritten into law; 2) democratic guidance was effective when equity-fairness to all-was not submerged to private or narrow interests.

Leopold, Luna B. Lag times for small drainage basins. 1991.

Scope and Content Note

Abstract: Over a period of ten years, simultaneous measurement of storm rainfall and resulting runoff during individual storms were made in small basins in the San Francisco Bay Area, California. By simple measurement, without any recording devices, data collected define a relation of basin lag time, expressed as time between center of mass of rainfall and center of mass of runoff, is a specific measure of some basin characteristics including the effect of urbanization. Originally published: Catena ; v. 18, no. 2 (April 1991).
Folder 1.28

Leopold, Luna B. Base level rise : gradient of deposition. 1992.

Scope and Content Note

Abstract: A rise in base level, as behind a check dam, causes deposition of sediment. When deposition is complete, the gradient of the deposited surface is only about half that of the original channel. This new gradient does not increase with time. No known method of computation explains how incoming sediment is transported over the low gradient zone of deposition. Originally published: Israel journal of earth sciences ; v. 41 (1992).
Folder 1.29

Leopold, Luna B.,J. N. Collins, and L. M. Collins. Hydrology of some tidal channels in estuarine marshland near San Francisco. 1993.

Scope and Content Note

Abstract: Measurements of velocity, depth, discharge, and slope were simultaneously made at ten gages along a natural estuarine channel 19,000 feet in length in Petaluma Marsh, California. Along the study reach the channel decreases from a width of 47 feet at its mouth to nearly zero at its headward extent, with accompanying decrease in depth. Though gage height varies with time in a smooth sinusoidal manner at all stations, this is not true for velocity, discharge, or slope. Originally published: Catena ; v. 20 (October 1993).
Folder 1.30

Leopold, Luna B., and Claudio Vita-Finzi. Valley changes in the Mediterranean and America and their effects on humans. 1998.

Scope and Content Note

Abstract: River valleys in the Mediterranean, the Near East, the southwestern United States, and Mexico have repeatedly alternated between alluviation and erosion, changing the availability of water and agricultural land. The timing and magnitude of the various episodes suggest that the principal cause is a shift in precipitation patterns. Human activity has distorted the severity and the initiation of these changes that have at times been beneficial and at other times detrimental to the local population. Originally published: Proceedings of the American Philosophical Society ; v. 142, no. 1 (March 1998).
