Which consequence results when subsurface aqueducts feeding Mughal gardens encounter highly impermeable clay layers?

💡 Explanation

A clay layer obstructs groundwater flow; because Darcy's law dictates flow rate depends on permeability, water buildup upstream causes reduced differential pressure via hydraulic GRADE LINE depression. Therefore, head diminishes, rather than increased evaporation or biofilm effects.
