Major Clay Step features near Shorty's Island on the Kootenai River near Bonners Ferry, ID

공공데이터포털

The major clay step features are defined as having a vertical face that is greater than 1.5 meters. The clay step features were qualitately identified using an underwater video monitoring sysyem. The extent and magnitude of the clay steps were mapped using a muliteam bathymetric echosounder system.

Elevation Contours of the Bathymetry near Shorty's Island and Myrtle Bend, Koootenai River near Bonners Ferry, ID, 2010

공공데이터포털

The elevation contour data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The contours were created from a surface raster (also referred to as digital elevation model) of the bathymetry data and displays the elevation in 1 meter intervals for the below water areas.

Surficial Sediment Facies features near Shorty's Island on the Kootenai River near Bonners Ferry, ID

공공데이터포털

The surficial bed-sediment facies, herein after referred to as the sediment facies, quantitatively describes the dominant sediment substrate on the surface of the river bed. Sediment facies categories were based on the grain size distribution of Wentworth (1922) which included the following ranges or combination of ranges: gravel (2-64mm), sand (0.063-2mm) and silt/clay (less than 0.063mm). An underwater video monitoring system UVMS was used to collect visual samples of the sediment facies determine the type and dominant size of the substrate, and record the geographical position of the substrate. UVMS data was collected intermittently at each site from 2006 – 2012.
