Which condition critically endangered Mesopotamian irrigation canal integrity during the Bronze Age?

💡 Explanation

When canals operate, suspended sediment transported by river water settles out of suspension during transport, leading to siltation because fluid velocity diminishes, thereby reducing the capacity of the irrigation system. Therefore silt accumulation resulted, rather than the options which are more heavily dependent on environmental shifts.
