Empirical Data

The following observational data sets were collected as part of the WW2100 project. Some of these data sets were used in development of plug-in models for Willamette Envision, others informed detailed, topic specific studies. Click on data set titles to access data and metadata, including links to related publications.

  • Snow and forest canopy - Transect and site based snow, forest canopy, and meteorological data collected during the winters of 2011-2012 through 2015-2016 within the McKenzie and Middle Fork River Basins of the Oregon Cascades. Data were collected at open and forested sites in the low-, mid- and high seasonal snow zones.
  • Snow following forest fire - Snow water equivalent, snowpack surface debris concentrations, and micrometeorological conditions over snow in burned and unburned forest sites for three years following fire.  Data collected in the McKenzie River Basin for the years 2012-2014.
  • Land values - Parcel-level land use and land value data collected for randomly drawn samples of developed, agricultural, and forest land parcels in Benton, Lane, Marion, and Washington Counties for the years 1973, 1980, 1986, 1992, and 2000.  Data were used in development of the land-use transitions modeling component of WW2100.  
  • Irrigation survey - Data about irrigation decisions and crop choice collected through a survey of 530 Willamette valley farmers.  The survey was implemented in 2012 by the USDA National Agricultural Statistics Service.  Survey data informed development of the irrigation and crop choice modeling components of WW2100.
  • Willamette river fish - Fish sampling data collected at 167 Willamette River sites (96 mainstem and 71 sloughs) between 2011-2013.  The data were archived as part of the Willamette Fish Database, a comprehensive database of fish collected by Oregon State University and the Oregon Department of Fish and Wildlife in the Willamette River.
  • Water users survey - Mail survey of 1402 land owners in portions of Washington, Yamhill, Marion and Lane Counties. The survey gathered information about perceptions and priorities for water use and management, sociodemographics, and environmental world view. Contact Anita Morzillo for more information about this dataset.

 

Willamette Envision Code and Model Inputs

Willamette Envision code and data inputs to run Willamette Envision can be downloaded here. The version of the code archived here is version 331 from the ww2100svn subversion repository.  This version generated model outputs called WW2100 3.0.

Willamette Envision Model Outputs

Model outputs for WW2100 3.0 can be downloaded here, grouped by scenario.  WW2100 3.0 output was generated during summer and fall 2016 by Willamette Envision code version 330 and 331. Refer to the description files (linked from the table below) for details about each data set.  Four types of data can be downloaded:

  • Tabular output - 142 comma delimited files containing annual and daily values of model output such as basin-wide land use land cover trends by year, and daily values for stream discharge at specific locations. Output spans the range of sectors modeled with Willamette Envision. 
  • Decadal shapefiles - Attributed shapefiles of IDU map polygons, the spatial modeling unit used by Willamette Envision.  Many of the attributes are calculated as the model runs.  The shapefile for each decade includes attribute values for the last day of each decade of the simulation (e.g. December 31, 2019; December 31, 2029 etc.).
  • Binary outputs - The binary data includes values for each IDU map polygon and stream reaches for each day of the simulations (e.g. January 1, 2010-December 31, 2099). Types of output includes land cover, SWE, ET, precipitation, and stream discharge.  Binary data is available for eight WW2100 scenarios.
  • Cascade plots - Graphical summaries of model outputs for selected scenarios.  These plots were generated by Dr. Roy Haggerty using python scripts and tabular (csv) output from Willamette Envision 3.0 model runs.
