This paper describes the history of channel changes and associated pipeline exposure problems at five river and stream crossings in Alberta. Each case history reviews the various hydrologic and geomorphic factors that contributed to the erosion problem and describes the corrective action that was taken. A number of the examples illustrate the inherent difficulties in identifying potential erosion problems at the project design stage. Others show that with systematic monitoring and inspection procedures in place, remedial action can be planned and implemented well before pipeline integrity has been compromised.
