The Colorado River delta is a dramatically transformed landscape. Major changes to river hydrology and morpho-dynamics began following completion of Hoover Dam in 1936. Today, the Colorado River has an intermittent and/or ephemeral channel in much of its former delta. Initial incision of the river channel in the upstream ∼50 km...
Custom map projections for regional groundwater models
Eve L. Kuniansky
2017, Groundwater (55) 255-260
For regional groundwater flow models (areas greater than 100,000 km2), improper choice of map projection parameters can result in model error for boundary conditions dependent on area (recharge or evapotranspiration simulated by application of a rate using cell area from model discretization) and length (rivers simulated with head-dependent flux boundary)....
No evidence of infection or exposure to Highly Pathogenic Avian Influenzas in peridomestic wildlife on an affected poultry facility
Daniel A. Grear, Robert J. Dusek, Daniel P. Walsh, Jeffrey S. Hall
2017, Journal of Wildlife Diseases (53) 37-45
We evaluated the potential transmission of avian influenza viruses (AIV) in wildlife species in three settings in association with an outbreak at a poultry facility: 1) small birds and small mammals on a poultry facility that was affected with highly pathogenic AIV (HPAIV) in April 2015; 2) small birds and...
Divergent life histories of invasive round gobies (Neogobius melanostomus) in Lake Michigan and its tributaries
Matthew Kornis, Brian Weidel, M. Jake Vander Zanden
2017, Ecology of Freshwater Fish (26) 563-574
Round gobies (Neogobius melanostomus) have invaded benthic habitats of the Laurentian Great Lakes and connected tributary streams. Although connected, these two systems generally differ in temperature (Great Lakes are typically colder), food availability (Dreissenid mussels are more prevalent in Great Lakes), and system size and openness. Here, we compare round...
Stochastic programming with a joint chance constraint model for reservoir refill operation considering flood risk
Bin Xu, Scott E. Boyce, Yu Zhang, Qiang Liu, Le Guo, Ping-An Zhong
2017, Journal of Water Resources Planning and Management (143)
Reservoir refill operation modeling attempts to maximize a set of benefits while minimizing risks. The benefits and risks can be in opposition to each other, such as having enough water for hydropower generation while leaving enough room for flood protection. In addition to multiple objects, the uncertainty of streamflow can...
Bait type influences on catch and bycatch in tandem hoop nets set in reservoirs
James M. Long, David R. Stewart, Jeremy Shiflet, Dane Balsman, Daniel E. Shoup
2017, Fisheries Research (186) 102-108
Tandem hoop nets have become the primary gear for sampling channel catfish Ictalurus punctatus, but suffer from high incidences of bycatch, particularly aquatic turtles that usually drown as a result. We sought to determine if bait type, ZOTE© soap and ground cheese logs, would influence catch of channel catfish (CPUE...

Zhenduo Zhu, Davide Motta, P. Ryan Jackson, Marcelo H. Garcia
2017, Environmental Fluid Mechanics (17) 211-229
In December 2009, during a piscicide treatment targeting the invasive Asian carp in the Chicago Sanitary and Ship Canal, Rhodamine WT dye was released to track and document the transport and dispersion of the piscicide. In this study, two modeling approaches are presented to reproduce the advection and dispersion of...

David B. Bunnell, Tomas O. Hook, Cary D. Troy, Wentao Liu, Charles P. Madenjian, Jean V. Adams
2017, Canadian Journal of Fisheries and Aquatic Sciences (74) 306-315
In the Great Lakes region, multiple fish species display intra-specific spatial synchrony in 28 recruitment success, with inter-annual climate variation hypothesized as the most likely driver. 29 In Lake Michigan, we evaluated whether climatic or other physical variables could also induce 30 spatial synchrony across multiple species, including bloater (Coregonus...

Response of selenium concentrations in groundwater to seasonal canal leakage, lower Gunnison River Basin, Colorado, 2013
J.I. Linard, P.B. McMahon, L. R. Arnold, J.C. Thomas
2017, Scientific Investigations Report 2016-5047
Selenium is a water-quality concern in the lower Gunnison River Basin because irrigation water interacting with seleniferous soils derived from the Mancos Shale Formation has mobilized selenium and increased its concentrations in surface water. Understanding the occurrence of elevated selenium concentrations in groundwater is necessary because groundwater discharge is an...
Climate adaption and post-fire restoration of a foundational perennial in cold desert: Insights from intraspecific variation in response to weather
Martha M. Brabec, Matthew J. Germino, Bryce A. Richardson
2017, Journal of Applied Ecology (54) 293-302
1.The loss of foundational but fire-intolerant perennials such as sagebrush due to increases in fire size and frequency in semiarid regions has motivated efforts to restore them, often with mixed or even no success. Seeds of sagebrush Artemisia tridentata and related species must be moved considerable distances from seed source to...

Francisco J. M. Simões
2017, Conference Paper
A two-dimensional (depth-averaged) finite volume Godunov-type shallow water model developed for flow over complex topography is presented. The model, SToRM, is based on an unstructured cell-centered finite volume formulation and on nonlinear strong stability preserving Runge-Kutta time stepping schemes. The numerical discretization is founded on the classical and well established shallow...

Reservoir rehabilitations: Seeking the Fountain of Youth
Mark A. Pegg, Kevin L. Pope, L.A. Powell, Kelly C. Turek, Jonathan J. Spurgeon, Nathaniel T. Stewart, Nick P. Hogberg, Mark T. Porath
2017, Fisheries (40) 177-181
Aging of reservoirs alters the functions, and associated services, of these systems through time. The goal of habitat rehabilitation is often to alter the trajectory of the aging process such that the duration of the desired state is prolonged. There are two important characteristics in alteration of the trajectory—the amplitude...
From submarine to lacustrine groundwater discharge
Jorg Lewandowski, Karin Meinikmann, Franziska Poschke, Gunnar Nutzmann, Donald O. Rosenberry
2017, Conference Paper, Proceedings of the International Association of Hydrological Sciences
Submarine groundwater discharge (SGD) and its role in marine nutrient cycling are well known since the last decade. The freshwater equivalent, lacustrine groundwater discharge (LGD), is often still disregarded, although first reports of LGD are more than 50 years old. We identify nine different reasons why groundwater has long been...

Owing mainly to projected population growth, demand for freshwater on the Island of Oʻahu is expected to increase by about 26 percent between 2010 and 2030, according to the City and County of Honolulu. Estimates of groundwater recharge are needed to evaluate the availability of fresh groundwater. For this study,...
Chemical tracer methods
Richard W. Healy
2017, Book chapter, Estimating groundwater recharge

Use of modflow drain package for simulating inter-basin transfer in abandoned coal mines
Mark D. Kozar, Kurt J. McCoy
2017, Conference Paper, Proceedings America Society of Mining and Reclamation
Simulation of groundwater flow in abandoned mines is difficult, especially where flux to and from mines is unknown or poorly quantified, and inter-basin transfer of groundwater occurs. A 3-year study was conducted in the Elkhorn area, West Virginia to better understand groundwater-flow processes and inter-basin transfer in above drainage abandoned...
