Detailed Information and Explanation

  • readme.md: Explains the content of this HydroShare resource.
  • subset_nwm.ipynb.ipynb: A Jupyter notebook containing code that demonstrate the steps to successfully make an API request via the Subsetter Python Client to subset the National Water Model Versions 1-3 static data for a region of interest, defined by a bounding box.
  • DinkeyCreekWatershed_lcc.shp: Dinkey Creek watershed shapefile, containing the bounding box information in the Lambert Conformal Conic projection coordinate system.
  • DinkeyCreek.png: The map of the Dinkey Creek Watershed shown below, highlighting the Dinkey Creek head watershed and its sub-catchments.
  • channelgrid_comparison.png: Results of channel grid comparison across three versions of the National Water Model for the region of interest.
  • landuse_comparison.png: Results of land use comparison across three versions of the National Water Model for the region of interest.
  • Ksat_multiplier_comparison.png: Results of multiplier on saturated hydraulic conductivity for lateral flow direction comparison across three versions of the National Water Model for the region of interest.
  • auth_token.png: Example of the access token based on HydroShare credentials. This is intended for inclusion in the Jupyter Notebook description.

Comparison of Subset Data Results Across Three Versions of the National Water Model Domain

Below are some examples of differences in the subset data from various versions of the National Water Model for the Dinkey Creek Watershed. These variations matter, and it is important to select the appropriate version for subsetting to ensure the data best fits your specific objectives.

Channel Grid: Consistent across all versions.
Figure 2. Channel Grid: Consistent across all versions.
Land Use: Identical in versions 2 and 3, but differs in version 1.
Figure 3. Land Use: Identical in versions 2 and 3, but differs in version 1.
Land Use: Identical in versions 2 and 3, but differs in version 1.
Figure 4. Multiplier on Saturated Hydraulic Conductivity in Lateral Flow Direction: Varies across all versions.
