Flood Inundation Depth for a Flow of 2,130 cfs (stage 14) at Gage 14211500, Johnson Creek near Sycamore, Oregon (sycor_14.tif)

The basis for these features is U.S. Geological Survey Scientific Investigation Report 2017-5024 Flood Inundation Mapping Data for Johnson Creek near Sycamore, Oregon. The domain of the HEC-RAS hydraulic model is a 12.9 mile reach of Johnson Creek from just upstream of SE 174th Avenue in Portland, Oregon to its confluence with the Willamette River. Some of the hydraulics used in the model were taken from Federal Emergency Management Agency, 2010, Flood Insurance Study, City of Portland, Oregon, Multnomah, Clackamas and Washington Counties, Volume 1 of 3, November 26, 2010. The Digital Elevation Model (DEM) utilized for the project was developed from LiDAR data flown in 2015 and provided by the Oregon Department of Geology and Mineral Industries. Bridge decks are generally removed from DEMs as standard practice. Therefore, these features may be shown as inundated when they are not. Judgement should be used when estimating the usefulness of a bridge during flood flow. Comparing the bridge to the surrounding ground can be more informative in this respect than simply looking at the bridge itself. Two model plans were used in the creation of the flood layers. The first is a stable model plan using unsteady flow in which the maximum streamflow is held in place for a long period of time (a number of days) in order to replicate a steady model using an unsteady plan. The stable model plan produced the areas of uncertainty contained in the sycor_breach.shp shapefile. The second is an unstable model plan that uses unsteady flow in which the full hydrograph (rising and falling limb) is represented based on the hydrograph shape of the December 2015 peak annual flood.  The unstable model plan produced the flood extent polygons contained in the sycor.shp shapefile and the depth rasters and represents the best estimate of flood inundation for the given streamflow at U.S. Geological Survey streamgage 14211500.

Repeated drought alters resilience of seed bank regeneration in Taxodium distichum swamps of North America

Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central United States and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern United States. Along the Mississippi River Alluvial Valley and northern Gulf of Mexico, we investigated the capacity of seed banks to retain viable seeds after successive periods of drying and wetting in a greenhouse study. Mean differences of species richness and seed density were compared to examine the interactions of successive droughts, geographical location and water regime. The results showed that both species richness and total density of germinating seedlings decreased over repeated drought trials. These responses were more pronounced in geographical areas with higher annual mean temperature. In seed banks across the southeastern swamp region regions, most species were exhausted after Trial 2 or 3, except for semi-aquatic species in Illinois and Tennessee, and aquatic species in Texas. Distinct geographical trends in seed bank resistance to drought demonstrate that climate-induced drying of baldcypress swamps could influence the regeneration of species differently across their ranges. Despite the health of adult individuals, lack of regeneration may push ecosystems into a relict status. Seed bank depletion by germination without replenishment may be a major conservation threat in a future with recurring droughts far less severe than megadrought. Nevertheless, the protection of moist refugia might aid conservation.

4) Site information and photos

Seventeen streamflow-gaging stations, operated by the U.S. Geological Survey and distributed across the Ouachita Mountains of Arkansas and Oklahoma were selected for analysis. Regional hydraulic geometry curves relating drainage area to bankfull dimensions: cross-sectional area, top width, mean depth, and discharge, were developed from data collected at the selected streamflow-gaging stations. Bed material sampling was conducted to obtain information on the particle-size distributions of the streambed materials and to determine the shapes of the individual particles comprising the streambeds. The stream reaches at each streamflow-gaging station were classified using the Rosgen level II stream type (Rosgen, 1996) based on the average of stream channel metrics collected from site cross-sections and profiles. 
Descriptions of selected stream reaches are presented in the attached Comma-Separated Values (CSV) file. Descriptions for each site include the reach beginning and ending locations, the geology and soils at the reach, the land cover within the watershed, the streambed substrate type from the riffle cross sections within the reach, the entrenchment ratio, width-to-depth ratio, and sinuosity for the reach, the observed reach morphology, and the stream-type classification for the reach. 
Photos of selected stream reaches were obtained to document site conditions at the time of data collection. Approximately 350 photos are archived here in 15 zipped files, one for each study site. Each study site’s zipped file contains photo JPG files for that site and a CSV file listing the following photo attributes; 1) the photo file name, 2) the USGS streamflow gaging station number, 3) the USGS streamflow gaging station name, 4) the date the photo was taken, and 5) a description of the photo view. Note: Unfortunately, over the decade since much of the field work for this study was completed, some photos have been lost; including all of the photos for two sites (Rock Creek near Dierks, Ark and Alum Fork Saline River near Reform, Ark).

3) Streambed particle data

Seventeen streamflow-gaging stations, operated by the U.S. Geological Survey and distributed across the Ouachita Mountains of Arkansas and Oklahoma were selected for analysis. Bed material sampling was conducted to obtain information on the particle-size distributions of the streambed materials and to determine the shapes of the individual particles comprising the streambeds. Information on stream-bed particle-size distribution was used to compute the potential rate of bed-load transport and is a parameter used in the Rosgen (Rosgen, 1996) stream reach classification system. 
Streambed-material particle sizes were measured using two methods. The first method was Wolman pebble counts conducted across the riffles and pools within each study reach. A step-toe procedure was used to collect approximately 100 samples at each riffle and pool. Materials only from the active streambed were measured. For each sample the longest (A) axis, intermediate (B) axis, and shortest (C) axis were measured and recorded. From this pebble count data the bedrock tallies were removed and cumulative frequency curves were developed, from which the median (D50) and one standard deviation from the median (D16 and D84) particle sizes were determined. Bedrock is defined as any exposure of native solid rock in the streambed or along the streambanks. The second streambed-material particle-size sampling method was a sieve analysis of bar samples. A 5-gallon pail (approximately 50 – 60 lbs) of bar gravel was collected from the downstream face of a point-bar approximately 1/3 of the way down the face. The sample was dried and weighed to the nearest 0.1 of a gram to determine the total sample weight. The sample was then placed in a nest of sieves and a mechanical sieve shaker was used to shake the sample particles through the sieves. Next, the particles from each sieve were removed and weighed. The final total weights retained on each sieve were summed and compared to the original total weight before sieving. From the weight retained on each sieve cumulative frequency curves were developed, the median (D50) and one standard deviation from the median (D16 and D84) particles sizes were determined.

Koyukuk vegetation height

Yukon Flats National Wildlife Refuge (YKF NWR) and Koyukuk NWR (KUK NWR),  U.S. Fish and Wildlife Service (USFWS), initiated a project with the U.S. Geological Survey  Earth Resources Observation and Science (EROS) Center to acquire map products needed for moose habitat assessment. The objective of this work was to create a suite of products which included: Estimated Vegetation Heights, probability of Willow Estimates, and Vegetation Type Maps. These products are based on spectral characteristics found in bands 2 through 7 of Landsat 8 OLI scenes processed to surface reflectance, acquired in summer of 2013, and late winter of 2014. Training data was collected by fixed wing aircraft and helicopter by USFWS refuge staff, and extrapolated by the methods described. This  project,  “ Yukon Flats NWR willow mapping” (PI: Delia Vargas Kretsinger) was funded through the USFWS Inventory and Monitoring program via an Interagency Agreement between the USGS EROS and the USFWS – Alaska Regional Office.  The data products are provisional in nature and are intended to support USFWS land management decisions. These data have not been validated with independent test data but received favorable qualitative assessment by local field experts.

Coastwide Reference Monitoring System (CRMS) 2015 Site 0630 Land-Water Classification Data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum.  As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites.  A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2015 Color Infrared (CIR) Digital Imagery.  These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors.  The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition.  Three previous assessments have been conducted (2005, 2008, and 2012).  Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Everglades NP SET-MH Project Metadata (ver 2.0, July 2019)

Due to their position at the land-sea interface, coastal wetlands are sensitive to sea-level rise and many other aspects of global change. Small changes in coastal wetland surface elevation can lead to comparatively large changes in coastal wetland ecosystem structure and function, and in some cases wetland loss. The surface elevation table (SET)-marker horizon (MH) approach (SET-MH, together) is a method for quantifying net wetland surface elevation change while accounting for the relative contributions of various biological, geological, and hydrological processes that can occur within different segments of the soil profile (e.g., deep, shallow subsurface, and surface soil depths). This data release includes long-term and high temporal resolution surface elevation table (SET) and marker horizon (MH) data from nine study sites in Everglades National Park.
All data files and their associated metadata documentation can be found within "Everglades NP SET-MH Data (ver 2.0, July 2019).zip".
