Abstract:
Water velocities propagated to a continuous surface from the two dimensional hydraulogic modeling information for a specific reach and flow level listed in the data sets name.
Purpose:
This is part of a larger study known as the Yakima River Basin Water Storage Feasability Study (YRBWSFS). The modeling was conducted to support analysis of how fish habitats change in the reach specified in this data sets name, based on flow variations. The final data sets will be used to help determine how fish habitat will be effected by potential new water storage options.
Supplemental_Information:
This data set is part of a larger set of information.
Below is a listing of the modeled flows for each reach: Easton Reach - 250, 500, 700, 900, 1100, 1300, 1500, 1750, 2000 Kittitas Reach - 667, 800, 1032, 1288, 1700, 2311, 2770, 2864, 3146, 4000, 5000, 6500, 8000, 10000 Naches Reach - 250, 500, 720, 1000, 1500, 2000, 2680, 3000, 4000, 6000, 8000 Union Gap Reach - 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000 Wapato Reach - 300, 500, 750, 1491, 2000, 2450, 5000, 7500, 15000
For each flow level, the following data sets have been produced from the 2D hydraulic modeling: model points, water depth, water extent, water surface area, water velocity, habitats.
The following reaches in the Yakima River Basin have had similar data produced: Easton, Kittitas, Naches, Union Gap, Wapato
Reclamation conducted the 2D hydraulic modeling for the Easton, Kittitas, and Naches reaches. The USGS conducted the 2D hydraulic modeling for the Union Gap and Wapato reaches. Therefore, separate metadata files have been developed for these two sets of information.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Bureau of Reclamation's UCAO office received the modeling data from the USGS and have modified minor parts of it. The changes below could have resulting in some inaccuracies of the valiables of this original 2D modeling data, although it would be very minor. This is described in more detail at the end of the "Process Step" section. 1) Water surface elevation and water depth values for locations with a froude number of 0 were changed to -3.2808 (null value used in USBR modeled areas). 2) Water velocity values were changed to a value of 0 (to be consistent with USBR modeled areas) for locations with a froude number of 0.
Logical_Consistency_Report: raster topology exists

Completely finished for the project areas. The modeling was completed for the following reaches: Easton, Kittitas, Naches, Union Gap, Wapato.
Water variables were simulated from a two dimensional hydrodynamic model starting at rivermile 103.8, 1/4 mile south of Sunnyside diversion dam, and ending at rivermile 93.7, 1 .5 miles north of SR22 bridge at Toppenish.

Final accuracy unknown, but positional data used for hydrodynamic modeling was collected using USGS bathymetric sonar, RTK GPS and Total Station data.
Also, the propagation of the modeling point outputs to a continuous surface adds error, especially around the river edges.

Process_Step:
Process_Description:
This dataset is propagated from a two dimensional hydraulic modeling output. The modeling output almost always had points representing areas of flow being fully encompassed by points representing land, thereby having a river's edge boundary worked into the data.
The 'IDW' tool in ESRI's ArcGIS 9.x software was used to create this data set from the point outputs of the original modeling work. A distance limitation of 75 feet, value of 1 for the distance exponent, variable search radius, and cell size of 2 feet were used. The output was then clipped to the extents of the cooresponding water extent grid using the 'Con' tool in the same ESRI software.
A description of the original two dimensional hydraulic modeling work follows:
Model ouput variables were estimated for the Gap Reach of the Yakima River under steady-state flow by means of two-dimensional hydrodynamic modeling. The River 2D model used a two-dimensional finite element method to solve the two-dimensional shallow water flow equations. For a detailed explanation of the model, see Ghanem, A.H., P.M. Steffler, F.E. Hicks, and C. Katopodis, 1995, Two-dimensional finite element modeling of aquatic habitats:, Water Resources Engineering Report No. 95-S1, Department of Civil Engineering, University of Alberta, Edmonton, Alberta. The conditions simulated were for a flow of 283.17 cu. m/s with a downstream water surface elevation of 288.5 m. The bed elevation surface upon which the hydrodynamic simulation was based was derived from multiple survey methods ranging from USGS boat surveys to total station data collected in small secluded sections of this reach. Final mesh was irregulary spaced varying between 2.5 to 25 meters. Final CDG files from River2D were imported into ArGIS. The final data set is in the form of a ArcGIS shapefile.
Bureau of Reclamation's UCAO office received the modeling data from the USGS and have modified minor parts of it. The changes are listed below: 1) Metadata keywords changed to include both location and theme information. 2) Attribute names changed to reflect same naming convertions of USBR modeling work. 3) Vertical and horizontal accuracies changed from a value representing units in centimeters to units in meters. 4) Water surface elevation and water depth values for locations with a froude number of 0 were changed to -3.2808 (null value used in USBR modeled areas). For the Union Gap Reach at any modeled flow, this effected less that 0.0004% of the total 2D modeling points in the entire data set and less than 0.0034% of the pool designated 2D modeling points. The average depth of water in these areas was 0.7 inches. 5) Water velocity values were changed to a value of 0 (to be consistent with USBR modeled areas) for locations with a froude number of 0. 6) Certain attributes were deleted.
