Which long-term consequence affected Mughal gardens with pietra dura when subsidence increased irrigation demands?

💡 Explanation

Altered drainage patterns occur due to differential soil settlement impacting the *hydraulic gradient*, which caused uneven water distribution impacting pietra dura, because the water found new routes. Therefore, fountains risked failure and landscaping changed, rather than uniform operation.
