Jared L. Bottcher, Summer M. Burdick
2010, Open-File Report 2010-1261
Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) were listed as endangered in 1988 for a variety of reasons including apparent recruitment failure. Upper Klamath Lake, Oregon, and its tributaries are considered the most critical remaining habitat for these two species. Age-0 suckers are often abundant in Upper...

Avalanche ecology and large magnitude avalanche events: Glacier National Park, Montana, USA
Daniel B. Fagre, Erich H. Peitzsch
2010, Conference Paper, 2010 International snow science workshop
Large magnitude snow avalanches play an important role ecologically in terms of wildlife habitat, vegetation diversity, and sediment transport within a watershed. Ecological effects from these infrequent avalanches can last for decades. Understanding the frequency of such large magnitude avalanches is also critical to avalanche forecasting for the Going-to-the-Sun Road...

2010, Conference Paper, Land subsidence, associated hazards and the role of natural resources development: EISOLS 2010 proceedings
Competition for water resources is growing throughout California, particularly in the Central Valley where about 20% of all groundwater used in the United States is consumed for agriculture and urban water supply. Continued agricultural use coupled with urban growth and potential climate change would result in continued depletion of groundwater...
Climate warming-induced intensification of the hydrologic cycle: A review of the published record and assessment of the potential impacts on agriculture
Thomas G. Huntington
2010, Advances in Agronomy (109) 1-53
Climate warming is expected to intensify and accelerate the global hydrologic cycle resulting in increases in evaporation, evapotranspiration (ET), atmospheric water-vapor content, and precipitation. The strength of the hydrologic response, or sensitivity of the response for a given degree of warming, is a critical outstanding question in climatology and hydrology....
Hillslope hydrologic connectivity controls riparian groundwater turnover: Implications of catchment structure for riparian buffering and stream water sources
Kelsey G. Jencso, Brian L. McGlynn, Michael N. Gooseff, Kenneth E. Bencala, Steven M. Wondzell
2010, Water Resources Research (46)
Hydrologic connectivity between catchment upland and near stream areas is essential for the transmission of water, solutes, and nutrients to streams. However, our current understanding of the role of riparian zones in mediating landscape hydrologic connectivity and the catchment scale export of water and solutes is limited. We tested the...

Glenn A. Hodgkins
2010, Fact Sheet 2010-3034
To safely and economically design bridges, culverts, and other structures that are in or near streams (fig. 1 for example), it is necessary to determine the magnitude of peak streamflows such as the 100-year flow. Flood-frequency analyses use statistical methods to compute peak flows for selected recurrence intervals (100 years,...

Historical changes in annual peak flows in Maine and implications for flood-frequency analyses
Glenn A. Hodgkins
2010, Scientific Investigations Report 2010-5094
Flood-frequency analyses use statistical methods to compute peak streamflows for selected recurrence intervals— the average number of years between peak flows that are equal to or greater than a specified peak flow. Analyses are based on annual peak flows at a stream. It has long been assumed that the annual...
