Print this page Ice Engineering Part II – Ice Jams, Mitigation, and Winter Navigation
Vincent D. Reynolds, MBA, P.E.
Course Outline
This 8 hour course is the second part of a two part course on ice engineering. Part I provided the reader with the processes, and problem solutions for ice in rivers and channels. Part II will cover the problems of ice jams; ice flooding, winter navigation on inland waterways and the preparation of river ice management plans.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.

- How sheet ice forms;
- The location of the majority of ice events in the United States;
- The size of brash ice;
- Mitigation measures for permanent ice jams;
- The thermodynamics of ice melt;
- How ice accumulates in river beds;
- The methods of ice dusting;
- How to calculate the Froude Number;

- How to determine how much groundwater energy is transferred to ice sheets;
- The variables that influence heat transfer;
- How to define ice watch;
- How ice affects water elevation;
- How to determine the resulting crater size from ice blasts;
- Surfaces that require protection from ice;
- The energy density requirement for complete removal of ice using wall heater panels;
- The use of ice storage zones;
- How to define through cracks;
- How to determine the resistance value of a thermistor;
- How to determine the resistance encountered by vessels;
- How to determine the discharge of micro-hydroelectric power plants using net head;
- The coefficient friction for Teflon on vessel hulls;
- How to define black ice;
- Various ice jam mitigation measures;

- How to determine the power of a heating panel.
Intended Audience and Benefit
Ice formation along rivers and channels can have destructive effects on the surrounding environment. Ice can cause bridge scour, soil erosion, death of vegetation and aquatic life, flooding and mechanical malfunction of hydropower plants. Ice control employs various processes of ice removal, and solutions for navigating water bodies containing ice. Several procedures of controlling and eliminating ice will be covered in this course. Ice formation processes and physical properties will also be discussed.
