Wave Runup - Average Reservoir Depth

Click For Summary
SUMMARY

The calculation of wave run-up for a reservoir requires determining the average reservoir depth along the fetch line (D). For initial reservoir levels between 20ft and 35ft, D is calculated as D=0.5Ho. However, for levels exceeding 35ft, alternative methods must be employed. The U.S. Department of Corps of Engineers' Engineer Letter ETL 110-2-221 provides guidance on this topic, though access to the document may be limited. A relevant report detailing the calculation procedure can be found in Appendix B of the provided link.

PREREQUISITES

Hello!
In order to calculate wave run-up for a reservoir, I need to determine the average reservoir depth along fetch line (D).... Does anyone know how can I calculate this depth?

In some book I have read that D is the average reservoir level along the direction of wind blow, and it is assumed to be half of the initial reservoir, D=0.5Ho, but only for 20ft <Ho<35ft. In my case the initial reservoir level is more than 35ft.

Another books and works do mention of a Engineer Letter of the U.S. Department of Corp of Engineers, named ETL 110-2-221: Wave Runup and Wind Setup on Reservoir Embakment. But I have been unable to get this book.

I would appreciate any suggestion or advice.

Thank you very much!

The calculation procedure is explained in Appendix B.
