ICE ENGINEERING
1.
Purpose.
This manual, composed
of
three parts, presents in Part I the current guidance for the
planning, design, construction, and operation and maintenance
of
ice control and ice suppression
measures for Corps
of
Engineers projects; provides·
in
Part II the current guidance for dealing with ice
jams
and the resultant flooding, including preventive measures; and gives in Part III the current guidance
for. engineering and operational solutions to ice problems on rivers used for navigation.
2.
Applicability.
This manual is applicable to all USACE commands having responsibility for civil
works design, construction, operations, and maintenance.
3.
Distribution
statement.
Approved for public release, distribution is unlimited.
4.
References. Bibliographic material is included
atthe
end
of
each chapter where necessary.
5.
Discussion.
All Corps projects subjected to freezing temperatures have ice problems, such as: ice
buildup on lock walls, hydropower intakes, and lock approaches; ice accumulation in navigation
channels; ice passage over spillways that scours the downstream channels; and ice damage to shore
structures and shorelines, etc. Therefore, ice control measures should be considered for both
new
and
existing projects to improve operations and safety in cold .regions. In Part I, this manual contains a
discussion
of
ice formation processes, physical properties, and potential solutions to associated problems.
Part II considers the problem
of
ice
jams
and ice
jam
flooding, and discusses a broad range
of
mitigation
measures. Part III
of
this manual addresses the c.onsiderations that arise from winter navigation on inland
waterways, including the conduct
of
river ice management studies and the preparation
of
river ice
management plans.
