2021, JAWRA (54) 1151-1167
Geomorphic change from extreme events in large managed rivers has implications for river management. A steady-state, quasi-three-dimensional hydrodynamic model was applied to a 29-km reach of the Missouri River using 2011 flood data. Model results for an extreme flow (500-year recurrence interval [RI]) and an elevated managed flow (75-year RI)...

Anthony Paulson, Stephen E. Cox
2021, Applied Geochemistry (91) 149-161
Trace element contamination is known to be widely present in sediment of Lake Roosevelt and the riverine reach of the Columbia River in Washington State, USA due to discharges from several smelters and numerous mines dating back to the mid-1800's. In...

Bianca Viggiano, Tamara Dib, Nasim Ali, Larry G. Mastin, Raul Bayoan Cal, Stephen A. Solovitz
2021, Journal of Fluid Mechanics (836) 1009-1049
Geophysical flows occur over a large range of scales, with Reynolds numbers and Richardson numbers varying over several orders of magnitude. For this study, jets of different densities were ejected vertically into a large ambient region, considering conditions relevant to some geophysical phenomena. Using particle image velocimetry,...
Statistical implementations of agent-based demographic models
Mevin Hooten, Christopher K. Wikle, Michael R. Schwob
2020, International Statistical Review (88) 441-461
A variety of demographic statistical models exist for studying population dynamics when individuals can be tracked over time. In cases where data are missing due to imperfect detection of individuals, the associated measurement error can be accommodated under certain study designs (e.g., those that involve multiple surveys or replication). However, the interaction of...
A new approach to the study of relationship quality in dolphins: framework and preliminary results
Manon Themelin, Christine Ribic, Kel Melillo-Sweeting, Teri Bolton, Kathleen M. Dudzinski
2020, Behavioural Processes (181)
Proximity and synchronous behaviours from surface observations have been used to measure association patterns within and between dolphin dyads. To facilitate an investigation of relationship quality in dolphins, we applied a method used for chimpanzees and ravens that examined three main components to describe relationships: value, security, and compatibility. Using...

Animal movement models with mechanistic selection functions
Mevin Hooten, Xinyi Lu, Martha J. Garlick, James A. Powell
2020, Spatial Statistics (37)
A suite of statistical methods are used to study animal movement. Most of these methods treat animal trajectory data in one of three ways: as discrete pro- cesses, as continuous processes, or as point processes. We brie y review each of these approaches and then focus in on the latter. In the context of...

Lesser prairie-chicken (Tympanuchus pallidicinctus) use of man-made water sources
Trevor S. Gicklhorn, Clint W. Boal, Philip K. Borsdorf
2020, Southwestern Naturalist (65) 197-204
The lesser prairie-chicken (Tympanuchus pallidicinctus) occurs in the semiarid southern Great Plains, a region prone to periods of drought. Researchers generally believe that lesser prairie-chickens are able to satisfy their water requirements through preformed water and metabolic processes, but also know that they experience low survival and reproductive success during...

An exploration of parametric earthquake risk transfer solutions that dynamically adapt to seismicity changes
Guillermo Franco, R Guidotti, Edward H. Field, K.R. Milner, Y.J. Lee, R. S. Stein
2020, Conference Paper
(Re)insurance companies rely on earthquake risk models to estimate the frequency and severity of their potential financial losses. To protect themselves, they sometimes use parametric risk transfer solutions, which are derivative-form agreements that provide compensation as a function of routine measurable earthquake characteristics. These mechanisms typically remain in force for...

Juvenile Coho and Chinook salmon growth, size, and condition linked to watershed-scale salmon spawner abundance
Philip J. Joy, Craig A. Stricker, Renae Ivanoff, Shiao Y. Wang, Mark S. Wipfli, Andrew C. Seitz, Jiaqi Huang, Mathew B. Tyers
2020, Transactions of the American Fisheries Society (150) 307-326
Anadromous Pacific salmon Oncorhynchus spp. are semelparous, and resource subsidies from spawning adult salmon (marine-derived nutrients [MDN]) benefit juvenile salmonids while they rear in freshwater. However, it is unclear if juvenile salmon populations respond predictably to the abundance of spawning salmon at the watershed scale. To address whether hypothesized benefits to rearing...

Jeffrey A. Coe, Erin K. Bessette-Kirton, Dianne L. Brien, Mark E. Reid
2020, Conference Paper, Proceedings of the 13th International Symposium on Landslides
On September 20, 2017, Hurricane Maria triggered widespread debris flows in Puerto Rico. We used field observations and pre- and post-Maria lidar to study the volumetric growth of long-travelled (>400 m) debris flows in four basins. We found overall growth rates that ranged from 0.7 to 30.4 m3 per meter...
