50-275/323 Hydrologic Engineering guestions Intake Core Breakwaters I

1.

Provide the following information relating to the hydrologic design of the breakwater system:

a.

Describe the design wave field (wave height and period, direction and stillwater level) for breakwater stability.

Characterize the severity of this design wave field in relation to probable maximum type events and/or statistically.

b.

Provide detailed descriptions of the breakwater design.

Describe the various layers, the materials

used, the sizes, shapes and weights, and the slopes and elevations.

Include drawings and cross sections.

c.

Describe the analyses and/or modeling techniques to justify the breakwater design, i.e., that the breakwater will be able to survive the design wave conditions without loss of its safety functions.

2.

Provide the following information about the breakwaters as actually constructed:

a.

Describe any known differences between the breakwater as designed and as constructed.

Discuss the effect of any such differences on the breakwaters'bility to survive the design wave conditions.
