Maryam A. Lamjiri, Michael D. Dettinger, F. Martin Ralph, Nina S. Oakley, Jonathan J. Rutz
2018, San Francisco Estuary and Watershed Science (16) 1-17
California is regularly impacted by floods and droughts, primarily as a result of too many or too few atmospheric rivers (ARs). This study analyzes a two-decade-long hourly precipitation dataset from 176 California weather stations and a 3-hourly AR chronology to report variations in rainfall events across California and their association...
Geomorphic evolution of a gravel‐bed river under sediment‐starved vs. sediment‐rich conditions: River response to the world's largest dam removal
Amy E. East, Joshua B. Logan, Mark C. Mastin, Andrew C. Ritchie, Jennifer A. Bountry, Christopher S. Magirl, Joel B. Sankey
2018, Journal of Geophysical Research F: Earth Surface (123) 3338-3369
Understanding river response to sediment pulses is a fundamental problem in geomorphic process studies, with myriad implications for river management. However, because large sediment pulses are rare and usually unanticipated, they are seldom studied at field scale. We examine fluvial response to a massive (~20 Mt) sediment pulse released by the...

Steven T. Anderson, Hossein Jahediesfanjani
Peter D. Warwick, editor(s)
2018, Conference Paper, U.S. Association for Energy Economics and International Association for Energy Economics North American Conference
The conventional wisdom is that widespread deployment of carbon capture and storage (CCS) is likely necessary to be able to satisfy baseload electricity demand, to maintain diversity in the energy mix, and to achieve mitigation of carbon dioxide (CO2) emissions at lowest cost (IPCC, 2014). If national-scale deployment of CCS...

Land subsidence along the California Aqueduct in west-central San Joaquin Valley, California, 2003–10
Michelle Sneed, Justin T. Brandt, Michael Solt
2018, Scientific Investigations Report 2018-5144
Extensive groundwater withdrawal from the unconsolidated deposits in the San Joaquin Valley caused widespread aquifer-system compaction and resultant land subsidence from 1926 to 1970—locally exceeding 8.5 meters. The importation of surface water beginning in the early 1950s through the Delta-Mendota Canal and in the early 1970s through the California Aqueduct...
Influence of river discharge on grass carp occupancy dynamics in south-eastern Iowa rivers
Christopher J. Sullivan, Michael J. Weber, Clay Pierce, Carlos A. Camacho
Michael J. Weber, editor(s)
2018, River Research and Applications (35) 60-67
Despite the longstanding presence of grass carp Ctenopharyngodon idella in the Upper Mississippi River (UMR) watershed, information regarding their populations remains largely unknown, in part because capture is difficult. Occupancy models are a popular wildlife assessment tool to account for imperfect detections but have been slow to be adopted in fisheries. Herein,...

Douglas A. George, John L. Largier, Curt D. Storlazzi, Matthew J. Robart, Brian Gaylord
2018, Continental Shelf Research (171) 63-76
Sediment transport past rocky headlands has received less attention compared to transport along beaches. Here we explore, in a field-based study, possible pathways for sediment movement adjacent to Point Dume, a headland in Santa Monica Bay, California. This prominent shoreline feature is a nearly symmetrical, triangular-shaped promontory interior to the Santa Monica Littoral Cell. We collected...
