TECHNOLOGY TRANSFER

ERDC TN-DOER-T3

January 2001

The failure of the telescoping weir by pulling apart should be fully investigated, and correc-

tions should be made to either the design/fabrication or operating procedures or both.

The design basis for the telescoping weir needs to be better understood and documented for

future projects.

The possible ranges of design conditions (e.g., flow, salinity, suspended solids, etc.) should be

evaluated to provide the empirical basis for future designs.

TECHNOLOGY TRANSFER: The Innovative Technologies Focus Area under the DOER pro-

gram has been assisting the Norfolk District to transfer the technology to various Corps users, in-

cluding the Mobile District. The first inter-district technology transfer installation was in the Upper

Blakeley Island CDF in the upper Mobile Harbor, Alabama. Delivery and installation of the system

were completed on July 19, 2000. This partnership between the Mobile and Norfolk Districts and

the DOER program serves to promote the use of the telescoping weir and will aid in this technology

transfer to other Corps Districts.

The innovative device has high potential to be used throughout the Corps and industrial facilities

worldwide. Patents for the telescoping weir are being processed with the U.S. Patent and Trademark

Office and with foreign countries.

In addition to the technical assistance being provided under DOER, the U.S. Army Engineer Re-

search and Development Center has signed an agreement with the Norfolk District to license the

telescoping weir to commercial entities. Negotiations are presently ongoing with two companies to

license the technology for commercial sale. The telescoping weir should be fully licensed and avail-

able to the public in 2001.
