You can view spatial output from Willamette Envision simulations via an interactive map developed by OSU graduate student Dan Stephens. The map displays output from different model simulations.The simulations project how the landscape might change in response to changes in climate conditions, population growth, and land and water management policies. Please use Google Chrome or Firefox web browsers to view the map.
The map displays four types of output from modeling simulations -
The map displays a subset of WW2100 scenarios. The table below highlights key differences between the scenarios featured on the map. For more details about modeling scenarios and their assumptions, refer to the scenarios web page.
Scenario | Climate Change | Population Growth | Selected Management Assumptions |
Reference Case | middle range climate change; ~4°C (~7.5°F) increase in Willamette River Basin (WRB) annual mean temperatures over century | pop. in 2010 = 2.41M; 2100 = 5.37M |
- forest wildfire suppression at historical rates; forest area burned increases from 0.2%/yr in 2010 to 0.6%/yr in 2100 |
LowClim (Low Climate Change) | ~1°C (2°F) increase in WRB annual mean temps. over century | same as Reference Case | same as Reference Case |
HighClim (High Climate Change) | 6°C (~10.5°F) increase in WRB annual mean temps. over century | same as Reference Case | same as Reference Case |
High Population | same as Reference Case |
pop. growth rates within UGBs doubled relative to Ref; pop. in 2100 = 8.25M |
same as Reference Case |
Urban Expansion | same as Reference Case | same as Reference Case |
- urban growth boundaries expand when 70% developed; no urban reserves |
Fire Suppression | same as Reference Case | same as Reference Case |
- wildfire suppression efforts increase to hold area burned per year to historical rates |
Managed | same as Reference Case |
- differential increase in wildfire suppression on private and public lands; resulting increase in forest area burned on private lands from 0.2%/yr in 2010 to 0.3%/yr in 2100 and on public lands from 0.2%/yr in 2010 to 0.8%/yr in 2100 |

Worst Case | same as Reference Case | same as High Population |
- wildfire suppression same as Fire Suppression scenario |
One of the ways we compared output for different modeling simulations was by developing a water budget from model results. A water budget is an accounting of inputs, outputs and changes in the amount of water that flows through a project area. We used modeling output from Willamette Envision to estimate a water budget for the Willamette River Basin (WRB) and how that budget might change over the 21st century in response to climate change and population growth.
The interactive water budget displays inputs and outputs to the water budget in terms of water depth over the whole basin. For example, we estimate that if you summed all the water that falls over the entire basin in a year, and spread it out in an even layer over the whole basin, the water would be 162 cm deep, or just over five feet deep. We use these depth measurements as a way to compare the relative size of different parts of the water budget in the basin. The thickness of the blue lines in the interactive water budget correspond to the quantity of water that flows through the Willamette Basin, from left to right. The units shown are in of cm3/cm2/year (abbreviated as cm; 1 cm = 235,000 acre-feet).
Users can use a drop down box to view the water balance for different modeling simulations, and the slider to look at how fluxes change during different times of the year. The scenarios on the drop down menu allow users to switch between depictions of the water budget for the past (1950-2010) and for different future scenarios (2070-2100).
