2013, Bulletin of the Seismological Society of America (103) 542-558
The extent to which faults exhibit temporally varying slip rates has important consequences for models of fault mechanics and probabilistic seismic hazard. Here, we explore the temporal behavior of the dextral‐slip Warm Springs Valley fault system, which is part of a network of closely spaced (10–20 km) faults in the...

2013, Book chapter, Crowdsourcing geographic knowledge volunteered geographic information (VGI) in theory and practice
The Internet has brought many changes to the way geographic information is created and shared. One aspect that has not changed is metadata. Static spatial data quality descriptions were standardized in the mid-1990s and cannot accommodate the current climate of data creation where nonexperts are using mobile phones and other...

Development of regional skews for selected flood durations for the Central Valley Region, California, based on data through water year 2008
Jonathan R. Lamontagne, Jery R. Stedinger, Charles Berenbrock, Andrea G. Veilleux, Justin C. Ferris, Donna L. Knifong
2012, Scientific Investigations Report 2012-5130
Flood-frequency information is important in the Central Valley region of California because of the high risk of catastrophic flooding. Most traditional flood-frequency studies focus on peak flows, but for the assessment of the adequacy of reservoirs, levees, other flood control structures, sustained flood flow (flood duration) frequency data are needed....
Flood pulsing in the Sudd wetland: analysis of seasonal variations in 2 inundation and evapotranspiration in Southern Sudan
Gabriel B. Senay, L-M. Rebelo, M.P. McCartney
2012, Earth Interactions (16) 1-19
Located on the Bahr el Jebel in South Sudan, the Sudd is one of the largest floodplain wetlands in the world. Seasonal inundation drives the hydrologic, geomorphological, and ecological processes, and the annual flood pulse is essential to the functioning of the Sudd. Despite the importance of the flood pulse,...
Spatially telescoping measurements for improved characterization of groundwater-surface water interactions
Colin Kikuchi, Ty P.A. Ferre, Jeffery M. Welker
2012, Journal of Hydrology (446-447) 1-12
The suite of measurement methods available to characterize fluxes between groundwater and surface water is rapidly growing. However, there are few studies that examine approaches to design of field investigations that include multiple methods. We propose that performing field measurements in a spatially telescoping sequence improves measurement flexibility and accounts...
