Which catastrophic outcome developed due to silting within extensive Euphrates canals?

💡 Explanation

Decreased irrigation occurred due to the mechanism of sediment deposition reducing water flow, because decreased flows resulted in less transported water to fields located further away; therefore crop yields decreased, rather than structures collapsing or ceremonies not occurring.
