1 Waller Creek 8 th Street Side Weir CFD Modeling and Simulation ALDEN Research Laboratory Inc. 30 Shrewsbury St., Holden, MA Preliminary Results September 1, 2009 Scenario 4

2 Iso-surface plot of water colored with velocity magnitude (solid component is transparent to see the water surface) * velocity magnitude color scale shows the actual range of velocity values throughout the system (ft/s)

3 Iso-surface plot of water colored with velocity magnitude (solid component is not shown to see clearly the water surface) * velocity magnitude color scale shows the actual range of velocity values throughout the system (ft/s)

4 Iso-surface plot of water colored with free surface elevation (Plan view) (ft)

5 Iso-surface plot of water colored with free surface elevation (showing water surface elevation in the building) (ft)

6 Iso-surface plot of water colored with free surface elevation (showing water surface elevation downstream of inline weir) * note the color scale range: 458 ft. to 460 ft. (ft)

7 Plot of velocity contour with vectors (slice plane cut at elevation 457 ft.)

8 Plot of velocity contour with vectors (slice plane cut at elevation 457 ft.)

9 Plot of velocity contour with vectors (slice plane cut at elevation 455 ft.)

10 Plot of velocity contour with vectors (slice plane cut at elevation 455 ft.)

11 Plot of velocity contour (slice plane cut vertically at different locations.)

12 Plot of velocity contour with vectors (slice plane cut at elevation 445 ft.)

13 Plot of velocity contour with vectors (slice plane cut at elevation 445 ft.) * same with slide 12 except walls were removed for clear view under the net deck.

14 Plot of velocity contour with vectors (slice plane cut at elevation 445 ft.) * same with slide 13 with different color scale.

15 Plot of velocity contour with vectors (slice plane cut at elevation 445 ft.) * closer look at the building

16 Plot of velocity contour with vectors (slice plane cut at elevation 445 ft.) * same with slide 15 with different color scale.
