Patterns and processes of wetland loss in coastal Louisiana are complex: A reply to Turner 2001. Estimating the indirect effects of hydrologic change on wetland loss: If the Earth is curved, then how would we know it?
John W. Day, Gary P. Shaffer, Denise J. Reed, Donald R. Cahoon, Louis D. Britsch, Suzanne Hawes
2001, Estuaries (24) 647-651
The coastal wetlands of Louisiana comprise a vast expanse of marine to freshwater wetland plant communities interspersed w-ith shallow bays and bayous. These wetlands were built by processes associated with the present-day Mississippi and Atchatfalaya River deltas and older distributaries occupied by the river over the past 7,000 }rears. The high rates of wetland...
Using high-resolution aeromagnetic surveys to map subsurface hydrogeology in sediment-filled basins: A case study over the Rio Grande Rift, Central New Mexico, USA
V. J. S. Grauch
2001, Exploration Geophysics (32) 209-213
High-resolution aeromagnetic surveys were acquired for the Albuquerque basin in the central Rio Grande rift, a basin filled with poorly consolidated sediments. The surveys proved successful in efficiently and economically mapping previously unknown hydrogeologic features of the shallow subsurface. This success suggests that aeromagnetic methods may be useful in hydrogeologic...
Very different crustal response to extreme extension in the southern Basin and Range and Colorado Plateau transition
Tom Parsons, Jill McCarthy, George A. Thompson
2001, Book chapter, The geologic transition, high plateaus to Great Basin - A symposium and field guide (the Mackin volume)
Clustered about the southwest edge of the Colorado Plateau lie many highly extended terranes. Among these are metamorphic core complexes, distinguished by low-angle normal faults with sufficient offset to expose middle crustal rocks at higher elevation relative to the surrounding areas. About 150 km to the southwest, strong extension in...
Canopy disturbance patterns in a bottomland hardwood forest in northeast Arkansas, USA
Sammy L. King, T. J. Antrobus
2001, Wetlands (21) 543-553
We characterized canopy disturbance patterns in a bottomland hardwood forest and identified linkages to tree species characteristics and interannual flooding patterns. We located 116 newly formed canopy gaps created by 136 gapmakers of 13 species. Over 83% of the gapmakers were snapped or uprooted (i.e., windthrow). The probability of any...

Mechanics of debris flows and debris-laden flash floods
Richard M. Iverson, Roger P. Denlinger
2001, Conference Paper, Proceedings of the seventh federal interagency sedimentation conference, March 25 to 29, 2001, Reno, Nevada
A new mathematical model developed to predict behavior of debris flows and avalanches also holds promise for predicting behavior of debris-laden flash floods. The model assumes that debris flows behave as mixtures of interacting Newtonian fluids and Coulomb solids. Solid and fluid constituents obey three-dimensional mass and momentum balances, which...
A strategy for estimating tree canopy density using Landsat 7 ETM+ and high resolution images over large areas
Chengquan Huang, Limin Yang, Bruce K. Wylie, Collin G. Homer
2001, Conference Paper, Proceedings of the third international conference on geospatial information in agriculture and forestry
Forest cover is of great interest to a variety of scientific and land management applications, many of which require not only information on forest categories, but also tree canopy density. In previous studies, large area tree canopy density had been estimated at spatial resolutions of 1km or coarser using coarse...
Sequence stratigraphy of a South Florida carbonate ramp and bounding siliciclastics (late Miocene-Pliocene)
Kevin J. Cunningham, David Bukry, T. Sato, John A. Barron, Laura A. Guertin, Ronald S. Reese
2001, Book chapter, Geology and hydrology of Lee County, Florida. Special publication 49
In southern peninsular Florida, a late-early to early-late Pliocene carbonate ramp (Ochopee Limestone Member of the Tamiami Formation) is sandwiched between underlying marine siliciclastics of the late Miocene to early Pliocene Peace River Formation and an overlying late Pliocene unnamed sand. At least three depositional sequences (DS1, DS2, and DS3),...
