Abstract

This resource includes a calibrated Distributed Hydrology Soil Vegetation Model (DHSVM) for the Stillaguamish Watershed (Snohomish County, Washington). The tar.gz file is extractable and executable in a Unix environment. The model runs with a 1-hour timestep and was calibrated using observed streamflows from USGS and Washington Department of Ecology gaging sites throughout the watershed.

Additional study details, meteorological forcings for the model, and simulated data are provided on the project website linked in the Related Resources section below.

Stilly_PeakFlows.tar.gz
Extractable and executable calibrated model for the Stillaguamish watershed. The model does not include
any forcings; those can be downloaded from the project website linked below.

histobvs.zip
Extractable archive of four separate .csv files of observed streamflows from USGS and WADOE stream gaging sites. The data
are simplified into two rows, one for date:time and another for flow in cubic feet per second. Note that 
there are missing data and data qualifiers have been omitted.

Stillaguamish_PeakFlows_GIS_Layers.zip
Extractable archive of GIS data used to build the Stillaguamish model. Individual files include:
- 1005_1070m_pixels - vector file of pixels between 1005 and 1070 m in elevation. This elevation band was used to evaluate simulated snow water equivalence.
- DHSVM_Output_Locations - vector file of DHSVM streamflow output locations
- Soil_Thick - raster file of simulated soil thicknesses
- Stilly_10m_DEM_4_figs - raster mosaic of individual 10m DEMs covering the entire Stillaguamish basin; individual raster files were downloaded from: http://gis.ess.washington.edu/data/raster/tenmeter/byquad/index.html
- Stilly_Fill_DEM - raster elevation data above but resampled to 150 m; these were used in the Stillaguamish DSHVM
- Stilly_Mask - raster of watershed bounds (1s for cells in watershed, 0s for cells outside)
- Stilly_Poly_Mask - vector file of watershed bounds
- Stilly_Soils - raster of resampled STATSGO soils data 
- Stilly_Subbasins - vector file of three main tributaries in the Stillaguamish: Pilchuck Creek, North Fork, South Fork
- Stilly_Veg - raster of resampled 2016 NOAA C-CAP landcover data
- Stream_network - vector file of simulated stream channels in the Stillaguamish watershed
- WRF_Nodes_32148 - vector file showing the meteorological station network
