The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has overseen the collection, processing, and serving of bathymetric data since 1989. A systemic data collection for the Upper Mississippi River System (UMRS) was completed in 2010. Water depth in aquatic systems is important for describing the physical characteristics of a river. Bathymetric maps are used for conducting spatial inventories of the aquatic habitat and detecting bed and elevation changes due to sedimentation. Bathymetric data is widely used, specifically for studies of water level management alternatives, modeling navigation impacts and hydraulic conditions, and environmental...

An Acoustic Doppler Current Profiler (ADCP) was used to survey streamflow characteristics including total streamflow, velocity magnitude and secondary flow structure, and backscatter intensity at 29 cross-sections at the Myrtle Creek Bend on the Kootenai River on June 1, 2012. Each of the 29 cross-sections consisted of 4 transects or bank-to-bank coverage to obtain a representative velocity pattern. The mean daily streamflow was around 35,000 cubic feet per second or 1,005 cubic meters per second.

Separate data for floodplain elevation and bathymetry were collected on the Upper Mississippi River System (UMRS) by the US Army Corps of Engineers (USACE), Upper Mississippi River Restoration (UMRR) Program. While many information needs can be met by using these data separately, in many cases seamless elevation data across the river and its floodplain are needed. This seamless elevation surface was generated by merging lidar (i.e., floodplain elevation) and bathymetry data. Merging the data required special processing in the areas of transition between the two sources of data.

The U.S Geological Survey Scientific Investigations Map provides raster data that can be used to assess channel response to streamflow alteration scenarios indicated from computer modeling of streamflow and sediment-transport conditions. Each 0.3-meter raster cell represents the surface elevation as derived bathymetric and topographic surveys and verified with RTK GPS. The Yampa River in northwestern Colorado is the largest, relatively unregulated river system in the upper Colorado River Basin. Water from the Yampa River Basin continues to be sought for a number of municipal, industrial, and energy uses. It is anticipated that future water development within the Yampa River Basin above the amount of water development...

This part of DS 781 presents data for the bathymetry and shaded-relief maps of Offshore Scott Creek, California. The raster data file is included in "Bathymetry_OffshoreScottCreek.zip", which is accessible from http://dx.doi.org/10.5066/F7CJ8BJW.The bathymetry and shaded-relief maps of Offshore Scott Creek, California, were generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by Fugro Pelagos, and by the U.S. Geological Survey (USGS). Mapping was completed between 2006 and 2009, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders, as well as a 234-kHz SWATHplus bathymetric sidescan-sonar system. These mapping missions combined to collect...

Located in the northern tropical Pacific Ocean, Majuro is the capital of the Republic of the Marshall Islands. Majuro Atoll consists of a large, narrow landmass and a set of smaller perimeter islands surrounding a lagoon that is over 100 square miles in size. The waters surrounding the Majuro Atoll land areas are relatively shallow with poorly mapped bathymetry. However, the Pacific Ocean on the exterior of the coral atoll and the lagoon within its interior consist of deep bathymetry with steep slopes. The highest elevation of the Majuro Atoll is estimated at only 3-meters above sea level, which is the island community of Laura located on the western part of the atoll. At the eastern edge of the atoll lies the capital...

The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.

ORWA26_500UTM is a digital bathymetric surface grid of the seafloor offthe coast of Washington and Oregon. Grid cell spacing is 500m and theprojection is UTM Zone 10.The surface was produced by gridding National Ocean Service (NOS)Hydrographic Surveys collected between 1926 and 1974 (primarily1926 to 1930). This work includes the most recent bathymetric dataavailable on a regional scale over the inner to outer continental shelfoff the coast of Washington and Oregon. The results represent thebest available estimate of the seafloor morphology for the time periodcirca 1926.

The substrate enhancement pilot project (SEPP) extent GIS layer represents an area where an artificial substrate will be placed. The artificial substrate, consisting of a mixed size class of gravel, is aimed at providing a more suitable substrate for sturgeon eggs and early-life rearing habitat. The location of the SEPP extent was created by analyzing the egg-mat network, bathymetric features, surficial sediment facies, and streamflow characteristics. The egg-mat data represent points where sturgeon eggs were captured in previous years, indicating a preference of spawning location. The bathymetry and surficial sediment facies data were used to delineate areas that were relatively flat and completely within the areas...

A RESON SeaBat™ 7125 multibeam echosounder in conjunction with an Applanix Position Orientation Solution for Marine Vessels (POS MV™) WaveMaster system motion sensor, HYPACK®/HYSWEEP® navigation software, and Ashtech Z-Xtreme GPS receivers or Trimble R8 receivers was used to survey the Missouri River bed at 15 pipeline crossings at four different locations, at three power plant locations, and at one transmission tower during the 2011 flood event. The format of this data is a grid with each cell covering 0.5 meter by 0.5 meter. The elevation value (North American Vertical Datum, NAVD88) represented by each cell is the most probable elevation for that cell based on calculated Total Propagated Uncertainty (TPU) as...

Bathymetric survey data of the Brandon Road Dam spillway was collected on May 27 and May 28, 2015 by the US Geological Survey (USGS) using Trimble Real-Time Kinematic Global Positioning System (RTK-GPS) equipment. The base station was set up over a temporarily installed survey pin on both days. This pin was surveyed into an existing NGS benchmark (PID: BBCN12) within the Brandon Road Lock property. In wadeable sections, a GPS rover with 2.0 meter range pole and flat-foot was deployed. In sections unable to be waded, a 2.0 meter range pole was fix-mounted to a jon boat, and a boat-mounted Acoustic Doppler Current Profiler (ADCP) was used to collect the depth data. ADCP depth data were reviewed in the WinRiver II...
