Geometry of river channels: Discussion by William W. Emmett and Luna B. Leopold Geometry of river channels: Discussion by William W. Emmett and Luna B. Leopold
For many years river engineers and geomorphologists have sought a rationale for the general similarity that can be observed among river channels from various environments. Some aspects of this general comparability were noted a century ago by Playfair, and other aspects were examined in a more quantitative way approximately 10 yr ago by R. E. Horton. Such similarities with respect to the...

Downstream patterns of riverbed scour and fill Downstream patterns of riverbed scour and fill
Progress has been made in describing riverbed scour and fill at a given stream section. One needs only the data routinely collected at a stream-gaging station to observe scour and fill at that station. However, similar progress has not been made to determine whether or not the scour and fill observed at a given section extends over a relatively long reach of the channel. Gaging stations...

Government responsibility for land and water: Guardian or developer? Government responsibility for land and water: Guardian or developer?
Ideas and concepts become obsolete just as do specific techniques. Obsolescence is the inevitable companion of progress; in fact, it is a sign of progress, provided that the obsolescence is recognized.

Quantitation of microorganic compounds in waters of the Great Lakes by adsorption on activated carbon Quantitation of microorganic compounds in waters of the Great Lakes by adsorption on activated carbon
Microorganic compounds in waters of Lakes Michigan and Huron have been sampled by adsorption on activated carbon in filters installed aboard the M/V Cisco and at the Hammond Bay Laboratory of the U.S. Bureau of Commercial Fisheries. The organic compounds were eluted from the carbon according to techniques developed at the U.S. Public Health Service. On the assumption that chloroform...

Simple measurements of morphological changes in river channels and hillslopes Simple measurements of morphological changes in river channels and hillslopes
One of the principal types of observational evidence on climatic changes in the recent geologic past is in river position and elevation. It is well known that river channels, particularly those flowing through alluvium or on relatively soft bedrock, tend to develop flood plains by lateral migration of the channel. Abandoned flood plains at elevations distinctly above the present river...

Some climatic indicators in the period A.D. 1200-1400 in New Mexico Some climatic indicators in the period A.D. 1200-1400 in New Mexico
Three centuries before Columbus landed in America, the alluvial valleys of the south-western United States teemed with activity. The indigenous peoples had been building for 300 years a culture centred around community life based on flood-water farming and on hunting. A large number of pueblos had developed on sites earlier occupied by pit-house people. Community organization had brought...

The movement, heterogeneity, and rate of exploitation of walleyes in northern Green Bay, Lake Michigan, as determined by tagging The movement, heterogeneity, and rate of exploitation of walleyes in northern Green Bay, Lake Michigan, as determined by tagging
The Michigan waters of northern Green Bay are an important center for commercial and sport fishing. This 400-square-mile area has supported a commercial fishery for many years but the development of the intensive sport fishery is more recent, mostly since World War II. The commercial fishery is based on several species, whereas anglers are particularly interested in the walleye...
