Columbia River Flow Visualization

Following are visualization of columbia river region in washington state based on climate simulations data. The data provides information about snow coverage and river flow volumes at 5 station locations. The movies cover a time span of 20 years from Jan 1980 to Dec 1999.

Problems:

  • Text coloring/shading of station names

Particle System River Flow (Jun5,06)

Problems:

  • Splashing (Could be curbed to some extent,
    but it might be ok to leave it as well)

Deformation with snow (Jun5,06)

density

Problems:

  • Camera Movement (Still camera might be a good idea)
  • Coloring/Shading (some regions too dark and others too
    bright because of snow, we should consider monotonic coloring like below)
  • The flow disk are not easily visible. (Making them opaque might work)
