Assessing the impact of diffusion model on the turbulent transport and flame structure of premixed lean hydrogen flames: hydrogen dataAaron Fillo, PETER HAMLINGTON & Kyle Niemeyer
This dataset contains results from direct numerical simulations of premixed, three-dimensional, turbulent hydrogen/air flames, using the multicomponent and mixture-averaged diffusion models. In particular, this dataset contains information about the enstrophy budget and flame structure. We performed the simulations using the finite-difference code NGA; simulation details are described completely in the associated article.
An online survey of river restoration practitioners, engineers, and researchers was conducted to examine current practices and perspectives on how climate change is integrated into engineering designs for river restoration. Seventy-six responses were submitted to the survey. While the responses came from a wide range of demographies, respondents were most commonly men, age 35-44, with professional degrees working as practitioners in consulting firms. The most frequent respondents work in engineering or engineering geomorphology in the...
The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in the Willamette Valley have focused on the production of grass and forage seeds. In addition to growing over two-thirds of the nation’s cool-season grass seed,...

Discharge and suspended sediment a paired watershed study examining the effects of contemporary forest harvesting in the Oregon Coast RangeJeff Hatten, Catalina Segura, Kevin Bladon, Cody Hale, George G. Ice & John Stednick
Forest harvesting practices can expose mineral soils, decrease infiltration capacities of soils, disturb the stream bank and channel, and increase erosion and fine sediment supply to stream channels. To reduce nonpoint source sediment pollution associated with forest management activities and to maintain the high water quality typically provided from forests, best management practices (BMPs) were developed and implemented. The Alsea Watershed Study was an important early research site that lead to the development of contemporary...

The accessions used to create the Snap Bean Diversity Panel were 149 snap bean cultivars and germplasm lines selected from North American and European germplasm. This panel was developed with support from the Common Bean Coordinated Agriculture Project (USDA-NIFA grant no. 2009-85606-05964). The accompanying data set contains information, where known, about pod traits and plant growth habit, USDA-NPGS Plant Introduction (PI) number, who bred the cultivar, market class and pod sieve size, plant variety protection...
This dataset accompanies the manuscript Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities in Water Resources Research. Benthic macroinvertebrates were collected from samples taken annually during the first two weeks of August from 2002-2007 and again in 2017 at six sites in the South Fork McKenzie River. Taxonomy of samples collected prior to 2017 have been updated to be consistent with 2017 taxa designations.
This dataset contains records of identified benthic and aquatic emergent invertebrates from pre-timber harvest, post-timber harvest, and reference (no harvest) collection sites in the Hinkle Creek watershed. A variety of fish-bearing tributaries, fishless tributaries, and mainstem creek sites were sampled. Benthic invertebrates were collected using Serber nets and emergent adults were collected with emergence traps. Invertebrates were identified to the lowest practical taxonomic level.
Hyperspectral reflectance data of wheat in situ and lab scans infected with soilborne wheat mosaic virusMarja Haagsma, Christina Hagerty, Duncan Kroese & Elizabeth Jachens
Hyperspectral images were taken in a lab setting from wheat leaves and in situ from agricultural wheat fields and disease nursery. The goal of this research was to find infection of soilborne wheat mosaic virus in wheat for early detection using digital imagery, i.e., either hyperspectral or multispectral.

Vegetation, Bryophytes, Lichens, Environment, and Stand Dynamics in Forests of the Swan Valley, MontanaBruce McCune & Joseph A. Antos
We sampled vegetation, bryophytes, lichens, environment, and stand dynamics in 56 plots in the Swan Valley, Montana in 1975-1978. The data include complete inventory of trees in 375 m2 plots, with whole-plot ocular estimates of plant cover by species, transect sampling of the ground layer bryophytes and lichens with microplots, and point-based sampling of epiphytic bryophytes and lichens on tree trunks. Stand age and forest history were inferred by increment boring. Canopy density was measured...
A Literature-based Dataset Containing Statistical Compositions and Reactivities of Commercial and Novel Supplementary Cementitious MaterialsKeshav Bharadwaj, O. Burkan Isgor & W. Jason Weiss
This dataset contains the chemical composition and reactivities of commercially used SCMs such as silica fume, Class-F and Class-C fly ashes, slags, and calcined clays. The dataset also includes the chemical composition and reactivity (where available) for several SCMs that are currently not specified in standard specifications by ASTM or AASHTO such as fly ashes not conforming to ASTM C618, bottom ashes, and pumices. This dataset can be used (i) for the classification of SCMs...

To investigate the effects of logging, three small watersheds in the Alsea River basin on the west slope of the Oregon Coast Range were selected for study. This was an interdisciplinary investigation to evaluate the influence of specific logging methods on stream regimen and on aquatic resources. The study plan involved (1) clear-cut logging one watershed [Needle Branch Creek]; (2) a second watershed with smaller, more spaced clear cuts and a riparian stream buffer left...
Hyperspectral images were taken from March till October, 2018, of southwestern white pine (Pinus strobiformis), SWWP, seedlings of ten different seed-source families. Half of the seedlings were inoculated with white pine blister rust (Cronartium ribicola). Visual assessments of vigor coincided with hyperspectral data acquisition. The aim of the experiment was to use hyperspectral data to automaticaly and objectively identify infection and degree of infection in SWWP seedlings. Moreover, we developed and evaluated a feature importance...
We examined long-term changes in daily streamflow associated with forestry practices with two datasets (this one and the original Alsea Streamflow dataset(1972)) over a 60-year period (1959–2017) in the Alsea Watershed Study, Oregon Coast Range, Pacific Northwest, USA. In this contemporary period, 2006 to 2017 (12 water years), data were collected at 10-minute intervals, including three to eight years of pre-harvest data rating curves were developed. Based 40 to 55 stage-discharge data points collected for...
Wild ungulates compound herbicide-mediated simplification of early-successional plant communities in forest plantations - DatasetThomas Stokely
This dataset consists of vascular plant species cover estimates collected from 12, 1x1-m quadrats, nested within 15x15-m plots that excluded and were open to wild ungulate access. The wild ungulate exclusion experiment was conducted in young forest plantations (<6 years old), each randomly assigned to one of 3 silvicultural herbicide treatments or an untreated control, collected from 2011-2016 in the Oregon Coast Range, USA. Data were used in the analyses presented in Stokely et al....

Bathymetry data (measurements of the elevations of submerged surfaces like the seafloor and lake beds) are an important factor in many scientific, economic, and engineering disciplines. Bathymetric surveys are widely used for benthic habitat mapping, flood inundation modeling, marine resource delineation, and nautical charting. While this ubiquity makes the generation of bathymetric data a high priority, acquisition of this type of data by traditional means (echosounding and/or airborne bathymetric lidar) can be infeasible in many...
