During the construction of the Suez Canal, which risk significantly increased when excavating through highly saline soils?

💡 Explanation

When excavating highly saline soils, electrolysis increased because the saltwater acts as an electrolyte, accelerating the corrosion of iron tools/equipment. Therefore, accelerated corrosion resulted, rather than settlement, dredging inefficiency, or landslides which are primarily geotechnical failures.
