Which risk increases when irrigation canal soil experiences repeated saturation/desiccation cycles in the Indus Valley?

💡 Explanation

Repeated wetting and drying causes soil particles to detach; therefore increasing the canal's Siltation rate due to increased soil erosion; this is rather than biofouling, hydration failure, or salinity profile changes which are less directly linked to the cycles.
