13. ABSTRACT (Maximum 200 words)
Ice processes are capable of causing damage to Corps of Engineers flood control, water control, and navigation
projects each year. Monitoring of ice and other physical parameters is done by instrumentation in some instances
but is usually done manually. Measurements that require personnel to go on an ice cover can be risky or impos-
sible, depending on the ice cover's stability and the individual's training. This study seeks to identify and rank the
field measurements needed during winter conditions and the instrumentation required to make the measurements.
Existing and developing instrumentation was evaluated for in-situ and remote sensing capabilities. Methods of
transmitting, storing, and retrieving various types of ice data were explored for feasibility and practicality. Recom-
mendations are identified regarding the types of instrumentation, data transmission, and storage methods that
need to be improved or developed.
