Raymond W. Schaffranek, Marc A. Stewart, Daniel J. Nowacki
2008, Data Series 358
The U.S. Geological Survey collected hydrologic data between June 2004 and December 2005 to investigate the temporal and spatial nature of flow exchanges through culverts beneath State Road 9336 within Everglades National Park.

Deciphering landslide behavior using large-scale flume experiments
Mark E. Reid, Richard M. Iverson, Neal R. Iverson, Richard G. LaHusen, Dianne L. Brien, Matthew Logan
2008, Conference Paper, Proceedings of the First World Landslide Forum
Landslides can be triggered by a variety of hydrologic events and they can exhibit a wide range of movement dynamics. Effective prediction requires understanding these diverse behaviors. Precise evaluation in the field is difficult; as an alternative we performed a series of landslide initiation experiments in the large-scale, USGS debris-flow...
Incorporation of Fine-Grained Sediment Erodibility Measurements into Sediment Transport Modeling, Capitol Lake, Washington
Andrew W. Stevens, Guy Gelfenbaum, Edwin Elias, Craig Jones
2008, Open-File Report 2008-1340
Capitol Lake was created in 1951 with the construction of a concrete dam and control gate that prevented salt-water intrusion into the newly formed lake and regulated flow of the Deschutes River into southern Puget Sound. Physical processes associated with the former tidally dominated estuary were altered, and the dam...
Simulated effects of ground-water withdrawals and artificial recharge on discharge to streams, springs, and riparian vegetation in the Sierra Vista Subwatershed of the Upper San Pedro Basin, southeastern Arizona
Stanley A. Leake, Donald R. Pool, James M. Leenhouts
2008, Scientific Investigations Report 2008-5207
In the context of ground-water resources, “capture” or “streamflow depletion” refers to withdrawal-induced changes in inflow to or outflow from an aquifer. These concepts are helpful in understanding the effects of long-term development of ground-water resources. For the Upper San Pedro Basin in Arizona, USA and Sonora, Mexico, a recently...

Rivers and streams: Physical setting and adapted biota
Margaret A. Wilzbach, K.W. Cummins
2008, Book chapter, Encyclopedia of Ecology
Streams and rivers are enormously important, with their ecological, and economic value, greatly outweighing their significance on the landscape. Lotic ecology began in Europe with a focus on the distribution, abundance, and taxonomic composition of aquatic organisms and in North American with a focus on fishery biology. Since 1980, stream/river...

Boreal soil carbon dynamics under a changing climate: A model inversion approach
Zhaosheng Fan, Jason C. Neff, Jennifer W. Harden, Kimberly P. Wickland
2008, Journal of Geophysical Research Biogeosciences (113)
Several fundamental but important factors controlling the feedback of boreal organic carbon (OC) to climate change were examined using a mechanistic model of soil OC dynamics, including the combined effects of temperature and moisture on the decomposition of OC and the factors controlling carbon quality and decomposition with depth. To...
The Landslide Handbook - A Guide to Understanding Landslides
Lynn M. Highland, Peter Bobrowsky
2008, Circular 1325
This handbook is intended to be a resource for people affected by landslides to acquire further knowledge, especially about the conditions that are unique to their neighborhoods and communities. Considerable literature and research are available concerning landslides, but unfortunately little of it is synthesized and integrated to address the geographically...
