Alex's sister, a geotechnical civil engineer, suggests a retaining wall tied back into the bank when discussing a canal repair. She expects modern repairs to use methods different from those available in 1971. Geotextiles and other slope-retention methods have developed in the intervening years. This is a preliminary suggestion; she has already said that she has not inspected the Bridgewater Canal problem herself.
