Inside The Beltway: Geography At The National Research Council, William Graf Dec 2010

Inside The Beltway: Geography At The National Research Council, William Graf

William L. Graf

Professor Graf provides ample reason why all geographers need to be cognizant of the work by the National Research Councils (NRC) two bodies focussed on mapping issues.“The importance of the two geography committees at NRC is that they give American geographers a voice in issues of national and international importance, and they put geographers on a similar footing with physicists, chemists, medical specialists, biologists, and other scientists.” Read about what has been done and how to get involved…only at Directions Magazine.

Fluvial Adjustments To Spread Of Tamarisk In Colorado Plateau Region, William Graf Dec 2010

Fluvial Adjustments To Spread Of Tamarisk In Colorado Plateau Region, William Graf

William L. Graf

Tamarisk, a shrub or low tree that was artificially introduced into the American Southwest in the late 1800s, has spread throughout the Colorado Plateau region by occupying islands, sand bars, and beaches along streams. Historical photographs show that tamarisk spread from northern Arizona to the upper reaches of the Colorado and Green Rivers at a rate of about 20 km/yr. Detailed studies on the Green River in Canyonlands National Park, Utah, show that the plant has trapped and stabilized sediment, causing an average reduction in channel width of 27%. Photogrammetric analysis of historical ground photography, including photos from John Wesley …

Relationship Between Morphology Of Small Streams And Sediment Yield, H. Chang, William Graf, E. Grissinger, H. Guy, W. Osterkamp, G. Parker, S. Trimble, L. Lane Dec 2010

Relationship Between Morphology Of Small Streams And Sediment Yield, H. Chang, William Graf, E. Grissinger, H. Guy, W. Osterkamp, G. Parker, S. Trimble, L. Lane

William L. Graf

The state of the art in the relations between morphology of small streams and sediment yield is assessed. Research findings and recommendations for additional research are presented. Topics include systems and interactions, simulation models, channel forms and processes, transport of sediment in small streams, and aspects of channel morphology. Selected topics for additional research are also included.

Science, Public-Policy, And Western American Rivers, William Graf Dec 2010

Science, Public-Policy, And Western American Rivers, William Graf

William L. Graf

Effective science and well-informed public policy are the avenues to successful management of environmental resources. A critical review of geomorphology, hydrology, and public policy as employed in the management of the river resources of the western United States shows that the endeavours have been poorly connected to each other. Before about 1930, river management disregarded scientific input, while during the New Deal era federal support for river research stimulated a symbiotic relationship between science and policy. Renewed federal funding for research and the emergence of increasingly sophisticated theory and data for rivers during the 1950-1970 period enhanced the connection between …


Streams, Slopes, And Suburban Development, William Graf Dec 2010

Streams, Slopes, And Suburban Development, William Graf

William L. Graf

The percent of available relief in the form of free-face slope and the percent of valley width as floodplain change systematically throughout drainage networks in response to changes in network position. The energy level and discharge of streams at the bases of slopes may be assessed by means of a cumulative stream-ordering system wherein the stream order is directly related to discharge. Investigations of several small drainage basins on the rim of the Denver Basin, Colorado, by means of field measurements, interpretation of aerial photography, and operation of a computer model provide data that indicate that the distribution of near-channel …


The Big Unanswered Questions In Geography, Reginald Golledge, William Graf, Susan Cutter Dec 2010

The Big Unanswered Questions In Geography, Reginald Golledge, William Graf, Susan Cutter

William L. Graf

In noting his fondness for geography, John Noble Wilford, science correspondent for The New York Times, nevertheless challenged the discipline to articulate those big questions in our field, ones that would generate public interest, media attention, and the respect of policymakers. This article presents our collective judgments on those significant issues that warrant disciplinary research. We phrase these as a series of ten questions in the hopes of stimulating a dialogue and collective research agenda for the future and the next generation of geographic professionals.
