When excessive rainfall saturates stepped terrace systems, which failure mode is most likely?

💡 Explanation

Slope destabilization can occur due to increased pore water pressure via hydrostatic pressure increase within terrace walls. Failure occurs because pore pressure overcomes wall shear strength; therefore, collapse is favored rather than soil erosion or thermal related effects.
