Which outcome primarily arises when road construction obstructs downslope solifluction across Arctic permafrost?

💡 Explanation

Increased hydrostatic pressure results; blocking downslope movement of saturated soil via solifluction causes a water buildup behind the obstruction because the permafrost prevents drainage; therefore pressure increases, rather than reduction, and impacts road stability versus other options.
