MIL-HDBK-1025/5
For design details, refer to DM-25.4, Seawalls,
Design Details.
2.4.5.3
Bulkheads, and Quaywalls.
General Considerations
2.4.5.4
Timber bulkheads often fail because of corrosion, abrasion,
a)
fatigue failure of metal connections, or abrasion of the wood by loose
connections, and not so much as a result of deterioration of wood members.
Steel or aluminum sheet pile bulkhead can be installed
b)
expeditiously and at a relatively low cost with lightweight sheet pile
sections.
Commonly used construction is a concrete wall with a vertical
c)
or slightly battered face extending to about extreme low water level, and an
armored slope extending from that level down to the design depth of the basin.
To prevent wave or eddy current scour at low water levels,
d)
armoring of revetted slope shall extend from the wall to about 5 ft (1.52 m)
below extreme low water.
Concrete perimeter bulkheads are the most durable.

Design Criteria for Entrance Channel and Protective Structures
2.5
Entrance Channel
2.5.1
Location
2.5.1.1
For siting entrance or approach channel, consider:
a)
1) Natural water depths
2) Character of waves approaching the harbor.
Analyze the following data:
b)
1) Hydrographic (site bathymetry) survey.
2) Wave generation and refraction.
3) Littoral drift.
These include the following:
Design Criteria.
2.5.1.2
To the extent the harbor configuration and conditions allow,
a)
the channel alignment shall be as close to the natural channel alignment as
possible. Bends, where necessary, shall be gradual.
Minimum Width. For small boat traffic, provide minimum 50 ft
b)
(15.2 m) or 5 times the beam of the widest boat expected to be berthed in the
basin.
