Which risk increases when terrace construction lacks drainage channels?

💡 Explanation

Increased slope destabilization occurs because pore water pressure increases due to impeded drainage, reducing effective stress and soil strength, leading to landslides. Therefore structural collapse likelihood amplifies because pore pressure is building, rather than nutrient depletion caused by erosion.
