STRUCTURAL DESIGN OF REINFORCED CONCRETE U-SHAPED
CHANNELS, BASINS, AND DROP STRUCTURES
1. Purpose. The purpose of this engineer technical letter (ETL) is to
facilitate the structural design of low-hazard, U-shaped, channels, basins,
and drop structures. The ETL summarizes Soil Conservation Service (SCS)
experience and criteria, discusses the differences between SCS and Corps of
Engineers practices, and provides guidance on the use of puter
programs developed by SCS and one program developed by the Corps for the
design of these structures.
2. Applicability. This ETL applies to all HQUSACE/OCE elements, major
mands, districts, laboratories, and separate field-operating
activities having civil works responsibilities for the design of civil works
projects.
3. References. Corps programs may be requested from the . Army Engineer
