What primary outcome resulted across ancient Samaria from silt deposition within irrigation canals?

💡 Explanation

Silt accumulation increased channel roughness, thereby raising water levels due to reduced flow capacity. Because canal beds aggraded, therefore irrigation reliability was undermined during crucial growth stages, rather than leading to a favorable outcome for crop production.
