During ancient Mesopotamian irrigation, which risk increased when canal siltation blocked aqueduct supply channels?

💡 Explanation

When canal siltation blocked supply channels, soil salinization increased because reduced water flow limits leaching leading to salt accumulation in soil pores, harming plants via osmosis. This meant salinity risk increased, rather than structural collapse, overtopping or cracking, which require physical forces acting upon their respective superstructures.
