A vertically faced 90-deg wedge-shaped pier on the Rideau river in Ottawa has been instrumented to measure ice impact forces. The pier is fitted with a frame which allows various sensors to be used to measure ice impact loads. Measurements have been made for three winters with two different types of ice sensors. A maximum impact force of 50 kN was obtained from direct measurements and a maximum local impact pressure of 6 MPa over an area of 0.01 m2 was indirectly estimated.
