Which consequence results when terraced hillside irrigation canals overflow?

💡 Explanation

Topsoil depletion accelerates because overland flow exceeds the infiltration capacity of the terraced soil structure; overland flow via sheet erosion removes the uppermost layer of the soil profile, therefore the terraced field's ability to retain nutrients diminishes rather than supporting crop biomass productivity.
