REVIEW:
ISRP Review (ISRP 2002-8)

Recommendation:
Fund - Rank 10

Date:
May 24, 2002

Comment:

This tenth ranked proposal is innovative, technically excellent, and covers an important topic. The proposal meets a regional need in adapting and applying well-known methods and software to help the region better understand the benefits and consequences of spill events and to forecast the effects of changes in spillway configurations designed to reduce gas supersaturation.

Computational Fluid Dynamics (CFD) models are being used for many hydraulic applications, and it is logical to try it here. The adaptation is innovative in that it combines deterministic equations with limited use of statistical models to understand the magnitude and distribution of dissolved gases below spillways. The logic for the model seems good. The proponents are well qualified to do the work, and the collaboration between ENSR and the Corps is an excellent mix of interests, capabilities, and eventual users.

The problem of modeling air entrainment in the plunge pool is particularly important to solve. The basic concept that mass exchange of gas between bubbles and water is an equilibrium process where the history of bubbles entrained below the spillway in time controls the TDG below the spillway has a firm basis in physical science. The success of the modeling effort will be tested against data at Bonneville Dam spillway, but Bonneville Dam may not be the best place to test this model.

The original submittal did not meet the cost limitations of the solicitation.

Do Not Fund

Comment:

This proposal did not meet the criteria outlined in the solicitation package. The proposal is redundant to activities that are already occurring through the FCRPS BiOp. There is already a MASS 2 numerical model and a SYSTDG spreadsheet model that have been developed for this purpose.

Comment:

Statement of Potential Biological Benefit
Indirect benefits. Potentially improves water quality by developing a model to evaluate design and operational concepts for reducing TDG generated by spillway operations at FCRPS projects and other dams. Has the potential to reduce mortality caused by high TDG levels.

Comments
The proposal is redundant to activities that are already occurring through the FCRPS BiOp. There is already a MASS 2 numerical model and a SYSTDG spreadsheet model that have been developed for this purpose. The ISRP was more supportive and gave the proposal a #10 ranking because they felt that modeling air entrainment in the plunge pool is particularly important to solve.
